WN Flange manufacturers Flanges are also called flange flanges or flanges. Flange is a part that connects between shaft and shaft and is used for connection between pipe ends; WN Flange manufacturers it is also useful for flanges on the inlet and outlet of equipment for connection between two equipment, such as reducer flange. Let’s follow the editor of WN Flange to take a look at its welding process!
1. quality WN Flange Preparation before welding
1. Check and debug the equipment to ensure that the equipment is operating normally.
2. To prepare φ4.0J402 welding rod, it is recommended to dry it at 300℃-350℃ for one hour.
Second, quality WN Flange the welding process
1. Assembly Assemble the cone and the large flange according to the drawing requirements, and then divide the large flange into 8 equal parts.
2. Welding Because the flange is thicker and the groove is larger, segmented symmetrical and multilayer welding is adopted.
3. WN Flange manufacturers Weld quality
WN Flange suppliers The weld strength is required to reach at least the strength of the base metal. The surface of the welding seam is flat and smooth, and there are no defects such as burn through, pores, weld leakage, slag inclusion, undercut, and insufficient weld. The remaining height is less than 2mm.
