What is a full strength penetration weld? Part 2
What is a full strength penetration weld? Part 2
(OP)
Hi all,
Can someone please elaborate on what a "full strength penetration weld"? I needed to specify some welding to join two pieces of a cut wide flange section. I was told to use a "full strength penetration weld". Is this description sufficient to tell the contractor what to do. I would have thought something like a butt weld might work. Can I specify a certain thickness of butt weld, for instance, for this work? What kind of a weld is it? Butt weld? Fillet? What does "full strength" and "penetration" mean? Someone in the structural engineering forum (hence the Part 2) said that "full strength" is not the same as "full penetration" and suggested posting here.
Thank you much.

If you had a fillet or partial penetration weld joint, a strength reduction factor would be used as some percentage of the base metal strength.

The CJP could be considered "full strength" as long as you used matching strength electrodes. CJP welds by definition are the full thickness of the base metal.
