Welding angle iron is one of the many welding jobs that you might need to do. It is a skill that takes time to perfect. Welders use the technique for many types of projects, from metalwork to home repairs.

Angle iron is a type of metal that has two different pieces, called legs. The top piece has a 90-degree bend at one end and the other leg extends straight out from it. This allows for building structures like girders or bridges.

Although, welding angle iron is a difficult process. It requires precision and the right tools to complete. However, in this blog post, we will cover what you need to know about welding angle iron and how to do it correctly.

If you follow these steps, it will be easy for even beginners to weld angle iron.

Why Should You Use Angle Iron?

Iron pieces have a variety of uses in construction. One popular use is for structural repairs; the angle iron can be attached to wood frame members, adding strength and shape. But it's not just about strengthening things-Angle Iron components are often used as fencing material. The component parts need only be welded together into an open framework with holes on either side which allow you to attach whatever type of fence you're looking for (like wrought iron).

Welding Angle Iron: Step By Step Process

It can be tricky to weld an angle on a steel frame, but it is not impossible. Here I give you few steps that can help you.

  • Tools needed to weld angles: MIG welder, gloves, safety glasses or goggles, oxygen/acetylene torch with a nozzle set at a 45-degree angle (optional), flux core wire feeder (optional), Chop Saw, Angle Grinder, Chipping Hammer, wire brush.
  • Types of welding rods used for welding angles - E6010, E7018, ER70S-6, ER80S-D2

The step by step processes for welding angle iron are given below:

Step 1:

First, clean both ends of the angle iron with a wire brush. Use safety gloves while cleaning the edges. For optimum penetration and better appearance, use a flux core welding rod-like E6010 or ER70S-6 for your project. It will help in the easy flow of molten metal into the base materials without letting air enter during the welding process. But if you prefer the solid wire feeder then go ahead with it.

Step 2:

Set up your MIG welder at 230V and make sure both start and main switches are off before connecting any power source to it as shown below:

The shielding gas which is used to protect molten material from oxidation should be connected to an Argon / CO2 mixture regulator and a torch or welding gun.

Step 3:

It is important to wear proper safety gear like gloves, goggles, and a face mask to prevent injury to the eyes and body. When using a shielding gas while welding, it is even more important that you protect your eyes from any escaping gases with a good pair of goggles.

Invest in good quality leather gloves when working on this project as they offer better grip than cloth ones which can impede the regular movement of your hands during work. Always keep in mind that the use of cheap flimsy gloves with poor grip will not only make the job difficult for yourself but also increase the chances of accidents or mistakes especially if there are lots of heat involved in the process.

Now clamp both ends of your angle and in order to prevent it from moving hold it tight against a non-flammable surface like an iron table. Now set your MIG welder at 100 amps.

Step 4:

Turn on the main switch of the welding machine and activate your gas supply either through a handheld torch or wire feeder, then turn on the start switch. When you see molten metal spraying out, move the torch 45 degrees to create a nice beveled edge weld at both joints. The flame should be pointing down towards your workpiece with a 1/8" gap between them. Remember to keep changing polarity every few seconds or use a pulsing DC current so that you don't burn yourself during this process. A good way is to use an E6010 or ER70S-6 wire which is flux-covered and doesn't create a lot of slags.

The welding gun or torch should be held at a 45-degree angle above the workpiece in order to produce smooth edges and a nice-looking welded joint.

Step 5:

If you are using flux core welding rods such as E7018 then the wand must be kept at 45 degrees for both start and main switches. When you see molten metal forming on the edge of your material, pull away from it but do not let it drop down as this is where most of the spatter collects. It's better to keep moving your welding gun up and down along the length while feeding the wire until you have attached an adequate amount of metal to both sides.

Now you should be good to go, and if everything went well then you can remove the clamps and admire your new angle iron frame which is now strong enough to handle any load that it may have to support in the future.

Step 6:

After removing all your setup tools like MIG welder, torch, etc. immediately turn off the main switch and then disconnect the hose from the nozzle. Once this is done safely put away all the equipment where they belong before cleaning up a bit at your workstation. Your project is now complete and ready for use if you wish to keep it as such or do something more with it by painting or staining it so that its color matches the rest of your home décor.

As you can see, it's not that hard to weld an angle on an iron frame if you have the right tools and know-how to use them.

Just remember these few pointers and then move on to your own projects for now apart from what we have written here.

Keep in mind that there is no one magical solution or method that will work for everything so keep trying different techniques until you find the one which works best for your materials when making a particular project or structure.

Always read instructions carefully before starting and wear proper safety gear at all times during work as this helps reduce the chances of accident or injury occurring in case something goes wrong before, during, or after doing any welding job on your new angle iron frame.

What is angle iron used for?

Angle iron is a specific type of metal, which bends at a particular angle (in order to make it durable) which gives it an inherent strength.

Its most commonly found as structural support in construction and factories because it can be awkward to transport long pieces of useable steel.

Angle iron is also used in personal aspects because screws are easily accessible and screws are often the easiest way to connect two pieces together with no welding necessary.

Angle iron is most commonly used in construction to construct and reinforce buildings, bridges, balconies, and other structures. Angle iron can also be found within everyday applications including Bed Frames, Seating, and Shelving.

  • Building Frames

The angle iron is a building material that is used in the construction industry. The metal is a part of almost every room of a home or building when framing. It’s typically found on-site and delivered to the place where it needs to be installed by using an excavator, crane, or forklift. Angle iron can also be made into different shapes like T-posts for fences, stakes for posts and walls, as well as L-angles for wooden structures like sheds and barns.

The angle iron comes with many benefits including versatility in shape and size which makes it easy to install anywhere there are two pieces meet. The steel has also been treated with zinc which prevents rusting from occurring during the installation process so you won't have to worry about the material cracking or breaking like untreated angle iron pieces. Since it's made out of steel and not wood, it can be used in almost any area even outside of a home for fences and garden sheds.

  • Bridges

Steel is a durable, strong material used in the construction of bridges. It is one of three major materials that are used for bridge-building. The other two being concrete and wood. Steel has many practical uses which make it a useful tool for any project, big or small.

  • Balconies

Angle iron is a versatile material in construction. It can be used to make sturdy structures and it's easy to work with because it will bend without breaking. Angle iron is also available at most hardware stores in standard lengths, so you don't have to cut the pieces yourself.

Best of all, angle iron comes pre-galvanized, which means that there's no need for painting or sealing after installation---it's ready for use right out of the box! Angle iron can be used in many different configurations: like posts, rails, or beams; as assembled panels; and even as a single piece spanning over an opening from one post on one side to another post on the other side.

  • Bed Frames

Metal bed frames are often made with angle iron. Angle iron pieces are also used for wooden frames to keep the pieces of the bed together and support the mattress that is set on top.

Metal beds, both traditional and modern, are often constructed from a combination of metal parts such as angles, rails, and bolts. Metal is durable against rusting compared to other materials like wood or plastic which can be damaged by moisture in air or humidity. It's important for all metal parts to be well-fitted so they don't move around during use. This may require some hammering or bending to get them into place but it will ensure their durability over time.

The length of an angle iron can vary depending on how long you need one. They are usually used in metal frames for beds to hold the vertical legs together. The length of angle iron can be measured from one corner to the other on the outside edges of the legs and that is where they will attach. It's important that all pieces are firmly attached so nothing wobbles or is loose in any way.

Angle irons are especially useful when making a bed frame made out of wooden slats that support the mattress above it. Since wood cannot typically bear immense weight, these metal bars help prevent sagging and provide some additional reinforcement so there aren't any weak spots in your new bed frame. If you have difficulty reaching corners with hammers, an angled piece of metal will work perfectly as well since it provides a slight bend that will allow you to get the job done with ease.

If your furniture is already built and you're searching for a way to reinforce sagging or broken bed frames, there are numerous metal pieces sold at hardware stores that can be used as extra reinforcement. Pieces like angle iron work well but also longer bars can be used around the perimeter of the frame to provide additional stability. Some wooden frames use these longer pieces as cross-members between vertical beams on one side or both so they prevent twisting during normal use and make sure everything remains structurally sound over time.

The right-sized angle iron should hold all areas together without any wobbling or sliding due to weight shifting towards one corner or another. The only thing that should move during use will be the mattress and other bedding above it. Spare metal pieces can also be used when making wooden frames but angle iron is typically a better choice since it fits around corners more easily than some of these other materials.

  • Seating

When you are looking for a material that can support the weight of more than one person, angle iron is often your best bet.

It's affordable and it offers strength without weight-which means it can be used in outdoor furniture as well as indoor seating.  Angle iron also has a sleek look, making it perfect for use in contemporary designs. Along with steel, aluminum, or plastic tubing, angle iron is an excellent choice to create pieces that will last for many years to come.

All you need to do is look around your office or house and you'll find angle iron holding up beds, computer desk chairs, tables, benches, and even playground equipment.

A standard piece of angle iron can easily be welded to a variety of other metal products in order to create larger seating areas that are also more durable than wood.

So next time you're shopping for outdoor furniture or indoor seating items for a commercial setting, consider the strength of angle iron as an affordable yet stylish option for your design needs.

  • Shelving

Angle iron is a piece of metal that can be used for many purposes.  It is usually made from steel, and the size varies. Angle iron pieces are often used in shelving because they provide support to the shelves while also holding up any objects on top of them. These brackets are strong enough by themselves or combined with other materials depending on what you're trying to do. For example, if you want your shelves to take a lot of weight, then it's best for these brackets to be screwed onto the wall so they don't fall over when something heavy is placed on top.

One of the main purposes of angle iron pieces is to hold up wood or other shelving. People use them because they're strong enough to hold up quite a bit of weight, and they're cheaper than most other materials that could be used for this purpose.

 Unlike brackets made of plastic, steel can hold a lot more weight. One downside to these pieces of iron is that they take time to install correctly. They must either be screwed onto the wall or at least attached strongly enough to ensure they don't fall down when something heavy goes on top. It's important to use stud mounts so the angle-iron won't just come straight out of the wall when objects are put on top.

The size and thickness of your angle iron depend on what you're trying to do with it. If you want your shelves or other things to hang off the floor then thicker ones should be used because thinner ones might not be able to support much weight as well. However, if you're only making a shelf that's going to be placed on top of the ground then it's better for thinner angle iron pieces to be used because they take up less room.

Safety Considerations when welding angle irons

Some of the safety considerations while welding angle irons are:

  • Consider the type of welding being done. If it is a MIG weld, it will have much less spatter than a TIG weld. A Stick weld will contain no spatter at all.
  • Wear safety glasses when welding and when grinding metal wool or wire. Wear gloves when handling hot metals and molten metal to protect your hands. If gloves are not available, use an oven mitt instead.
  • Keep in mind that most exhaust gases are toxic when inhaled, so make sure that you use some sort of ventilation for your work area. Welding produces carcinogenic gases that can cause cancer. Therefore, always wear a respirator if you're welding indoors to reduce the risk of inhaling harmful gases.
  • Avoid wearing loose clothing when welding or grinding and be careful not to drop any metal objects on your feet or body because it can lead to electric shock. Welding rods are extremely hot when they have just come out from being used on the welder so they should never be touched with bare hands. Always use gloves when handling them.
  • Keep combustible materials away from the welder area because sparks emitted from angle irons are very hot and can start fires easily if they land on flammable materials like newspapers, rags, sawdust, paints, lubricants, and other things. However, some people like to cover these materials with a thin layer of sand that would help them from spreading and starting a fire when they catch fire.
  • Make use of proper welder gloves since they can protect you from getting burned when the rod touches your fingers or hands during welding. Always wear gloves that are designed for metalwork because welding rods will make burns on unprotected skin surfaces.
  • Do not weld while standing up if you have not been trained to do so. If by chance you happen to fall down when working on your project, most likely you will land on your feet and suffer injuries instead of landing face-down with a risk of getting severe burns from burning metal oxides under the angle irons. You may also want to wear a helmet or hard hat for protection.
  • Never smoke when welding and try not to use grinders nearby because sparks can easily start fires while you are feeding the welder with wire. You may want to have a fire extinguisher handy nearby just in case your welder catches fire unexpectedly. Also, never weld angle irons on the ground because they will produce large amounts of toxic fumes that can cause health problems like neurological damage, cancer, and pneumonia, etc., so make sure that your work area is well ventilated at all times. Do not breathe in too much of those harmful gases by getting close while welding. Keep distance from where you're working before turning on the air compressor if it uses compressed air as its source of power (it should be labeled on the machine)
  • Never take a hot metal off the table and put it somewhere because it may end up falling down and starting a fire on your floor if you are using it indoors. Wait until the metal cools down before removing it from the table or cart.
  • If you don't have any ventilation for the area where you're working, consider moving to another room for your own health safety.
  • Always wear hearing protection devices (earplugs) when welding angle irons nearby with any kind of power tools especially grinding machines that produce loud noises. This is to protect your ears' sensitivity from experiencing noise trauma which can damage your eardrums permanently if exposed to loud noises over a long period of like.
  • When you're done with your welding project, make sure that you turn off the welder and its other accessories and clean up all the metal oxides on the area where you were working before leaving. If you leave them where they can continue burning for hours even if no source of heat is available nearby. Make sure that none of these accumulate in spots that are likely to cause a fire hazard later on. When grinding angle irons around combustible materials, always wear hearing protection to prevent noise trauma (especially from grinders).
  • Do not weld any angle irons in areas where children may play because most likely they will pick up hot pieces of metal left around by mistake and get them injured. A good way to learn more about this is by reading your instruction manual or contacting the manufacturer directly. You can also do further research on related topics, too, like other precautions you should consider while welding angle irons and which gas to use. You can improve your chances of getting a high score in language arts if you know how to make your article more interesting with these techniques.


If you're looking for a way to weld angle iron, it's important that you understand the properties of this versatile metal. The most common use for welding angle irons is in construction projects because they are strong and durable. For safety reasons, be sure your work area has adequate ventilation when using an acetylene torch or electric arc welder. Using gloves while handling hot objects can also prevent burns.
