General engineering question - sheetmetal welding in real life
MIG or TIG welding? please clarify answer, needed for welding thicknesses up to 1.5mm. Steel is the material
Welding an entire seam or just in certain spots to hold it together? If you run an entire seam MIG welding puts out too much heat. It will warp thin material and it will stay that way after welding and could warp worse while cooling. TIG welding is better for thin material since it concentrates the heat right at the weld and doesn't propegate far.
If you only need it welded in spots then it could be done with a MIG.
Regardless of welding method, structural steel below 3mm thickness is not recommended to weld more than 20mm in length `couse weld produce high amount of stress in welding core and you risk to put in jeopardy flatness of surrounding sheet metal parts due heat exchange in material...try to use soldering with flame torch and soldering silver (lower heat exposure)...or if is not possible, try to make some tools to keep flat elements flat...either way, TIG is better solution...:)
hope it helps...enjoy:)
