Thin sheet welding
Ensuring stability – avoiding thermal distortion
Welding thin plates up to 3 mm thick is one of the most complex joining tasks. The aim is to create a stable connection despite the thin material gauge. To prevent distortion of the metal plate and time-consuming reworking, as little heat as possible needs to be generated on the work surface. This requires lots of experience, finesse and welding equipment that is capable of working precisely in every situation.
MAG (GMAW) welding is the rule
Depending on the material, thin sheet metal is mostly welded as a MAG process. This allows a relatively high process speed, ensures high weld seam strength and leads to low warpage with little rework. Other welding processes suitable for thin sheet metal work are MIG and TIG welding. These are particularly suitable for corner seams and drop seam positions.
Using the right torch
It is always important to select the right torch for the requirements to ensure the best welding results in terms of quality and work speed. Torches need to be as light as possible and ergonomic, and also work precisely when used continuously. They also need to ensure that the wire is supplied evenly, as well as being low-maintenance and service-friendly.
