The process of connecting stainless steel can be carried out in different ways, among which they most often use: arc welding with an electrode, manual arc welding, as well as impulse. As for manual welding of an arc, it is relevant when working with sheets with a thickness of one and a half millimeter, while arc welding with an electrode in an inert gas environment provides somewhat greater performance. Its use is relevant in the case of working with stainless sheets that have a thickness of less than the above value.
Pulse -type welding, in which the electrode is also placed in the gas environment, is used for welding stainless steel0.8 millimeters. Now, among modifications of this type, more and more often use the types of stainless steel welding, for example, high -frequency laser welding.
The choice of one or another approach depends on the targeted use of the product, as a result of which the order of the stainless tape involves a preliminary assessment of other aspects, for example, the exposure of the metal to the formation of cracks. If the welded leaf stainless steel is planned to be used in aggressive environments, then it should be characterized by corrosion resistance. So heat treatment should be selected especially carefully. Nevertheless, regardless of the method of welding, the working seam is always tended to be covered with oxide film, which in turn is characterized by reducing the anti -corrosion qualities of the material, in view of which the seam should be polished immediately after work.
Welded joints are best done, since the correctly performed process of etching helps to restore a layer resistant to corrosion. As soon as the metal was trampled by polishing or grinding it, one can achieve greater stability.
