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, MAG welding procedure is usually applied on thin sheet metal. This allows a relatively high process speed, ensures high weld strength and leads to little distortion and reworking. MIG and TIG (GTAW) welding are also suitable for welding thin sheet metal, especially corner welds and vertical welds that are common, for instance, when building control cabinets.
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.
