201 stainless steel plate Metal surface treatment, cleaning the surface of stainless steel plate in tightly connected areas is important for welding. Use organic solvents to remove oil and vegetable oils. Brush on stainless steel plates and grind with sandpaper to remove other types of environmental pollution, leaving a shiny surface.

The mild surface roughness of 201 stainless steel plate is acceptable and can improve the adhesion of welding materials. Welding operation will be carried out immediately after cleaning. If this cannot be guaranteed, components can be electroplated with solder to maintain them.

The flux application of the auxiliary solution removes metal oxides from the surface of the stainless steel sheet. The auxiliary solution based on ammonium sulfate is also very suitable. If all residues remain after the whole process of tight connection, it has a harmless advantage. However, it must be noted that some fluxes based on ammonium sulfate contain sulfuric acid. When welding stainless steel plates containing molybdenum, the application of flux based on sulfuric acid should be prevented, which will cause poor cleaning of the connector after welding. Although the rosin type flux has no practical effect, they can be applied when it is necessary to pre-coat the surface layer of the stainless steel sheet.

All traditional heating methods can be used to weld 201 stainless steel plate. Only the low-alloy steel plate has relatively low heat transfer properties, so it is important to pay attention to ensure that the tightly connected area will exceed the welding temperature symmetrically and not easily overheat. Deformation occurs at the interface.
