How to control the dead zone of welded structures
Thread Content
Dear masters, in order to avoid the polymerization of media in pressure vessels, it is necessary to prevent the dead zone of the welding structure. Specifically, what aspects of the welding structure are controlled? Please ask for help, wait online, etc., please help me~
For example, the gap between the heat exchange tube and the tube plate hole, weld undercut, incomplete welding, etc., try to use butt welds for welding, grind the welds flat, and try to use full penetration structures. These are all ways to avoid welding dead zones.
