Metric Welding
Metric Welding
(OP)
I have a fabrication drawing from the UK that has a z3, z6, and such in front of the weld symbol were weld size usually goes. What does that mean? I doubt it means 3mm, 6mm, etc. since it is on an aluminum structure.

I know that with ANSI/AWS, the size is always to the left of the symbol and the length is always to the right of the symbol regardless of which side the leader is on.
Just to clear up my original post, when I sad the z6 was in front of the symbol, I was referring to the left of the symbol.

I have seen comparable details that the field had assumed was a leg size, when in reality it was referencing a size that was on a separate detail drawing, which varied based on component thickness.

Can you post the drawing (or a part of it)?
It is possible, but very unlikely, or incorrectly specified/drawed.
It has to be said, UK has always done things differently than on the mainland, so they might have adopted USA standards in this particular case?
