WELDING SYMBOL - AWS 1

[ShanXXX]

Hi All,


I’m still relatively new to AWS welding symbols and need some help understanding the one below. I’ve searched through various references but couldn’t find a clear explanation.


From what I can tell, it looks like a fillet weld, but that seems incorrect since the joint is a butt joint. Also, I’m unsure what the number “1” refers to in this context.

Yes, that is incorrectly drawn as a double sided fillet weld. It should be a butt joint as you have indicated. The “1” refers to the size or height of the fillet weld leg.

AWS A2.4 Weld Symbols is the best reference in the industry for definitions of welding symbols. I recommend anyone who deals with welding symbols to get a copy.

Is the weld symbol a metric product? The "1" may be 1 mm. I am not sure, I have never seen a weld symbol that uses metric.

I agree the symbol shows a fillet weld where you cannot create a fillet.

I also agree, A2.4 is the place to start.

As I recall the symbols, it is likely to require a square groove weld; the default is full penetration, but I'm a bit unsure when used on tubing, which this may be.
