Sanqing Pipe Industry In order to improve the production efficiency of stainless steel welded pipe fittings and the stability of welding quality, the welding method should be reasonably selected according to the material and wall thickness of the stainless steel welded pipe. The welding method of stainless steel welded pipe fittings should be selected according to the material and wall thickness of the welded stainless steel pipe. Because different welding methods have different arc heat and arc force, different welding methods have different characteristics.
stainless steel welded pipe fittings such as TIG stainless steel welded pipe fittings are characterized by low current density, stable arc combustion, and good weld formation. It is especially suitable for thin plate welding, while thick plate welding is not the first choice; plasma arc It is characterized by high arc column temperature, high energy density, good plasma arc flatness, wide rigidity and flexibility adjustment range, stable operation, but complicated operation. Submerged arc welding has the characteristics of strong penetration ability and high wire deposition efficiency, so the welding speed can be greatly increased, the welding cost is low, but the working conditions and environment are relatively poor. It can be seen that different welding methods have different capabilities and different operating costs. According to the material and wall thickness of the welded pipe, choosing a reasonable welding method is a very important work to ensure welding quality, improve productivity and reduce costs.
Stainless Steel Clamping Fittings In addition, the same welding method, such as the type and size of welding current, arc voltage, welding speed and welding materials used, have a great influence on arc heat and arc force. Therefore, different welding methods can only adapt to welding of different materials and thicknesses; for example, DC TIG welding is only suitable for welding thin-walled tubes, while AC TIG welding can only weld aluminum alloy thin-walled tubes. Different welding methods are suitable for the welding speed range of different thickness stainless steel. The selection of
stainless steel welded pipe welding method and the determination of process parameters shall be comprehensively considered according to the material and wall thickness, and shall meet the following requirements:
1. Ensure that the welding quality meets the requirements of relevant standards;
2. The welding process should be stable and reliable (with few faults and welding defects);
3. The welding speed should be fast, the production efficiency is high;
4. The welding cost and consumption are the lowest. The above articles should be coordinated with each other, and one article should not be unilaterally emphasized while other aspects are ignored, otherwise the expected effect will not be achieved.
