At SMI we are certified for the most common welding techniques: MIG welding (process 131), MAG welding (process 135 and 136) and TIG welding (process 141)
TIG uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an shielding gas such as argon or helium. TIG is ideal for welding sheet metal up to 3 mm but can weld a maximum thickness up to 6 mm.
MIG uses a wire feeding gun that feeds wire and flows an argon or helim-based shielding gas over the weld to protect it from contamination. As argo or helium is used as a shielding gas, MIG welding is ideal for aluminium or stainless steel as it prevents corrosion of the material.
MAG welding is ideal to weld steal structures and products together. MAG is identical to MIG welding, the only difference is that an active gas is used. That is why in the technical world it is common as MIG/MAG welding. MAG welding is used to weld steal structures and products together.
For both process, the welding thickness can be up to 50 mm.
Because of the wide range of welding processes, SMI can weld; steel, high strength steel, wear resistant steel, stainless steel and aluminum. Depending on the application and purpose of the final product, SMI Maatwerk can give the necessary advice on which materials should be used. For example, for our offshore market it is common that high strength steel is used as these products have to handle heavy loads and structures.
Welding other materials such as steel requires a high amount of expertise. SMI in-house expertise makes sure that the quality and properties of the materials such as high strength steel and aluminum are not lost during the welding process.
