All our tests are done in house as our QA are loyds certified
We do a pull test to stretch it till it snaps on a 10mm section and record the tons it takes,
Then freeze with co'2 to minus 80deg to do an impact test then a rockwell hardness test on and off the weld to see it hasnt cooled to quickly and gone brittle.



Im not sure what tests are done on alloy but i know its more strict and its much harder to get a good weld with no cavities .
We use stick and tig more than mig as its beter out on plant and much stronger.
