Full pen weld on butt joint of tube
Full pen weld on butt joint of tube
(OP)
I need your guidance:
I have tube steel that needs to be jointed at a splice point that requires full pen welding. I must develop the joint.
AWS does not provide a pre-qualified full pen joint. I am asking that the welder must be a 6GR qualified/certified. Do I need also have qualified for new joint? If so, what is the right verbiage to put on the plans?

You have part of it covered but we need more information as to sizes and materials of the tube in question and if possible the thickness the welder would or has qualified to.
If we know your tube sizes we can specify what qualification the welder has to have.

You can make the butt joint with backing using a "prequalified joint" WPS.

I actually was reading the right AWS section 3.13.3, however, I misread it.
I can make a full pen joint with welding being done from one side and use backing bar. I will require the joint to be tested using magnetic particle.
