Information
The processing of stainless steel flanges needs to understand and pay attention to some issues:
1. Weld defect: The weld defect of stainless steel flange is more serious. If it is compensated by manual mechanical grinding treatment method, the resulting grinding traces will cause uneven surface and affect the appearance;
2. Uneven grinding and polishing passivation: After manual grinding and polishing, pickling and passivation treatment is performed. It is difficult to achieve a uniform and uniform treatment effect on a large-area workpiece, and it is impossible to obtain an ideal uniform surface. There are also its shortcomings such as the cost of working hours and the cost of accessories;
3. Scratches are difficult to remove: overall pickling and passivation, chemical corrosion or electrochemical corrosion will occur and rust in the presence of corrosive media, and carbon steel that adheres to the surface of stainless steel due to scratches and welding splashes cannot be removed , Splashes and other impurities;
So how to solve the problem of stainless steel flange processing?
1. Select the blanking, and after completion, enter the next process, different stainless steel workpieces enter the corresponding process according to the processing requirements;
2. When bending, we must first determine the tool and sipe used for bending according to the size on the drawing and the thickness of the stainless steel 304 seamless steel pipe. Avoiding the product and the tool to cause deformation is the key to selecting the upper mold (in the same In a product, different types of upper molds may be used. The selection of lower molds is determined according to the thickness of the plate.
3. In order to weld firmly, make bumps on the workpiece to be welded, so that the bumps can be evenly contacted with the flat plate before welding to ensure the uniform heating of each point. At the same time, the welding position can also be determined. Good pre-compression time, holding time, maintenance time, rest time to ensure that the workpiece can be spot welded firmly.
