How to weld ½ inches steel with MIG welder?
Here is a procedure that will enable you to successfully weld a ½ inch steel using a MIG welder.
Brace the Joints
You need to ensure that you protect the ½ inch steel work piece from slipping when welding to prevent you from ruining the joint angle. Ensure it is well braced during the process of welding.
Distribute heat from the weld
When the heat that is generated by the welding process is not distributed evenly, it can easily cause cracks, burns and other issues. The mechanical precision and robotic control of welding will help by moving the welding arms precisely and quickly when the weld completes.
Choose the inert gas blend
It is important that you select the right gas for the material you will be welding. No one will want to use a completely inert shielding gas like 100% argon or 100% helium when welding a ½ inch steel with a MIG welder. It is because the MIG processes arc characteristics involves use of filler and are different from the TIG process.
Clean the Weld Joint
Using a filter material when welding can easily lead to a weld spatter which can become burrs or sharp and lead to injuries when touched by a person. To improve safety, it is advisable that you consider putting the welded stainless steel through process like electro polishing or sanding to help in removing the weld spatter sharps.
