5/16 angle weld

Date 01-21-2020 07:23

let me start by saying how helpful this forum is and how much I've learned and appreciate the responses I get using this forum, but I do have a new question is regards to welding angle, we have a weld joint where 1 angle butts up to the flat side of another angle letting us put 3 fillet welds around the angle and a butt weld on top, my question is the butt weld is required to have a flat contour(flat by grinding) and the weld joint does not have a bevel, is this type of joint fine because it has a 1/4" fillet weld on the back side of the butt joint or should there be a bevel for 100% CJP, I feel like im getting lost in D1.1 between CJP and PJP requirements, just needing some guidance here

Contours: If the weld symbol shows a grind flush contour, then you need to grind flush
AWS A2.4:2012 clauses 7.6.2, 7.7.4.1, 7.7.4.2, 8.6.1, 9.7, 10.9 and a few more talk about contours.

Is this what you have? If so, I'm thinking that what you are calling a butt weld is a square groove weld. Fillet weld at 3 sides, square groove at the top.

so I my question is, does that square groove weld have to be there at all, or does it need to have CJP?

Technically, the square groove is a pjp if welded from one side, but is limited to 1/4" material thickness. I see this used all of the time for materials over 1/4" just because the intention was to have that seam welded. Is it 100% correct? Not really, but what symbol do you use if you want the welder to weld it there?
