It is the California system that offers excellent technical and aesthetic guarantees, since it does not add material for thin and medium thicknesses, but limits the welding to the two edges to be joined by flashlight with tungsten electrode. The inert gas, fed into the welding phase, excludes oxygen, which is a cause of altering the molecular structure of steel and would make it attackable by liquids immersed in the container. For other sheet thicknesses, AISI 316 filler wire is also used. Constant digital control always ensures maximum weld accuracy.
