preheat purge procedure ua91 weld test

by steve

i will be taking 2 inch xxxh chrome test on Saturday. does anyone know an easier way to preheat and purge this coupon other than using a weed burner in my booth to the coupon set on angle iron heating it to 475 then trying to stick foil tape to the ends that the glue melts off & wont stick so i worry about not getting good purge? could someone please give me a better option?


Well this aint gonna help much since I am so late getting it posted.

what about a big wad of aluminum foil to plug the ends? with a piece of 1/4" stainless tubing inserted in the bottom wad of foil for the purge?

sorry about being so late. I am blaming everything on my wisdom teeth removal and subsequent drugs.
