Seeking help with a welding process issue regarding C276+16Mn
Thread Content
There is currently a Hastelloy C276 composite plate equipment; the flat cover has several connections, with a wall thickness of around 3–5 mm, and the thickness of the flat cover itself is about 50 mm, featuring a fully penetrated structure； May I ask what kind of plate butt weld assessment is required to cover this? Thank you.
Won’t this plug-in type leak during welding?
More than 2 weld evaluations may be required, 1 thin + 1 thick
If it’s a fillet weld, isn’t the thickness range unrestricted?……
