G'day,
I've recently welded my first piece of aluminium together (and on the
2nd try, I could even break it with my bare hands :) . I'm just beginning to learn welding, both TIG and SMAW.Now I've got a little project that I want to finish, consisting of a piece of angle aluminium (extruded), that needs to have 2 90-degree angles in it (U-shape).
Since I'm not yet very experienced (understatement...) at welding aluminium, I was wondering: can I place a small piece of stainless steel under my weld-zone, to prevent the aluminium from sagging (in case I put in too much heat). Perhaps a bit like the idea of using ceramic strips as is done sometimes in shipyard construction.
Yes, I know the best would be to get lots of practice and make sure I can do it right. However, as a bit of extra insurance for a beginner, might this help?
Peter.
