Welds between the lifting lug pad and the head
Thread Content
As the title suggests, which welding process should be used for this weld: 3G or 6FG?
No pressure resistance required; it’s a welded joint, and some skills are sufficient – no certification for pressure vessels is needed.
That’s wrong, right? Welds that are joined to stressed components require corresponding welder qualifications.

The lap joint is considered to exist between the lugs and the head; for the welding position, I use 2F, while for welder qualifications, 6FG is generally chosen

For non-compressed components, welding records are not required; if welding records are to be kept, I think 6FG would be appropriate
I think the opinion from the third floor is correct. Welds welded to pressure-bearing components
Not record it, to avoid unnecessary complications?
There should be no welds between the lugs and the head; I’m not sure what you’re trying to describe
These are side-mounted lugs; it’s possible he’s asking about top-mounted lugs
