When I went for the interview they asked me if I could ali weld and as I`d done Tig and Mig aluminium I said `yes`.Much to my Horror,I found you cannot use tig for Aston bodywork,The metal cools too quicky and the weld is harder.When you come to use a bodyspoon /slapper around the welded area(which has been annealed) it gives more than the weld and you end up with a ripple at best,or,fracturing the weld.Learning to weld ali was difficult ( you have to be fast and observant) but it makes for a great finish.Last week I went on a Blacksmiths course for `Fire welding` using just the heat from the forge to fuse the semi molten wrought iron together before hammmering it…now that was difficult.
