How to ensure full penetration in the welds between the nozzles and the shell of high-pressure vessels
Thread Content
As the title suggests, I’m seeking help on how to ensure full penetration when welding the nozzles and shell of high-pressure vessels It would be great if there were relevant information available: handshake:handshake:handshake. I’m not very familiar with welding processes, so I’d appreciate some advice from those who know more about this
It’s not easy to post about hair this year. . . .
Double-sided welding with root cleaning on the reverse side. . Are there any more detailed materials, such as information on preheating and inter-layer temperature control – and whether they are useful?
I’ll take care of it. Does anyone have any materials on this topic?
Selection of groove, selection of welding method. . . Double-sided welding is an effective way to ensure full penetration
TIG welding is used for the root pass, with double-sided formation, which generally ensures full penetration: victory:
What the poster really wants are welding process materials.
High-pressure vessels generally have thick walls, and X-shaped or U-shaped grooves can be used for 100% flaw detection
