does uncontrolled heating/melting of this aluminum weaken its "structure"? does aluminum have a structure? can welding weaken a tube if it's deformed a bit?
why do i ask? i have a new mountian bike frame and there's a bulge near one of the welds. the tube is not thin there, as there is no defect on the inside of the tube. just a 1 cm by 3-4 mm slight bulge on the outside of the tube. the manufacturer will exchange it but i don't want to bother if it's just cosmetic. any opinions? i have pictures if necesary. thanks
