Hello. I am using the variable polarity plasma arc welding process in an experiment to test the maximum thickness capability of the machine. I have some 0.380" 2219 aluminum plate and I was looking for the correct joint preparation procedure. Would this just be a square groove butt joint?
The 2nd joint is 0.500" 2219 aluminum. I have read that you can make a single pass weld using this VPPA process, but it's unclear to me as to how the joint should be prepared. Should I be using a v-groove joint design or square groove? If I need to v-groove it, how do I determine the correct root face, groove angle, etc.
Thanks.
