Hi Victorville!

First and foremost, "Weldcome to the World's Greatest Welding Forum!!!" :) :) :)

Which version (year) of AWS D1.1 are you referring to?

You also need to provide a whole lot more details in order to receive an informed answer to your application so, give us the specifics of the joint configuration, the shape your working with whether it be box tubing or pipe, at what angles are you working to, bevel angles, joint configuration, diameter, wall thickness, etc. And as many details as possible because with out the details, you might as well be working with folks that are blind, and we don't work that way!!! ;) :) :)

Respectfully,
Henry

For WPS Qualification you need to do more then Macro's. Take a look at Table 4.2 Part 2 "Testing on Pipe or Tubing. Then find the size of pipe you are using and it will tell you what tests need to be done. Also their might be more requirments from your customer.
