Welding of pressure guide tubes
Thread Content
There is a device with an angle of around 300° and a pressure of 45 kg. To measure the pressure, it is necessary to make holes in the flange cover; the material of the flange cover is 15CrMo, while the pressure transfer pipes are made of 316L. Can they be welded directly? Some experts say to perform direct welding by heating, while others suggest using an additional layer with a greater thickness as a cover. I would like to consult the welding experts here. BTW: If it’s in the wrong area, please ask the moderator to move it.
You can ask the equipment specialists; they are knowledgeable about welding materials and welding methods.
Please give me some advice. I’ve encountered the same problem. How did the original poster solve it? In my case, it’s a medium-pressure boiler operating at 450°C and 3.82 MPA. The material used for the boiler pipes is 15CrMO, while the pressure transfer pipes are made of 316L with dimensions of 14x2. Is it possible to weld them together?
It can be welded directly; the welding rod can be determined based on the equipment
