1. The arc starting method of stainless steel pipe fittings adopts the reflow method, and the arc closing method adopts the method of filling the arc crater. The arcing process should be completed within the slope, and arcing and arcing cannot be performed on the surface of the busbar of pipes and fittings. If cracks, pores, and other phenomena are found during the arc-starting process, they must be dealt with promptly.
2. When lifting, stainless steel pipe fittings should be separated from other metals to avoid direct contact. Non-metallic materials such as padded wooden boards and rubber boards can be used for isolation.
3. During continuous welding of stainless steel pipe fittings, the temperature should not exceed 60 degrees Celsius. During tack welding, the inside of the weld should be protected by argon filling. When cutting, you cannot use ordinary grinding wheels. You should use special grinding wheels for stainless steel pipe fittings or plasma cutting.
4. When connecting stainless steel pipes and non-stainless steel pipes and pipe fittings, the pipes and cavities of the welded butt joints should be filled with argon gas before welding, and then tungsten argon arc welding can be performed. The welds at the connecting welds must be pickled and passivated after welding.
