Yeah i've researching into welding 1.6mm, it would require buying some more rods and require a lot of practise as i dont want to end up blowing holes.
So does anyone know why ERW tube is used for chassis and the like? Whats so special about it? Does it add extra strength?
I have learned that ERW tube is made by taking a strip of metal and then folding or rolling it to the shape desired and then welding down the seam and cleaning off the outside weld.
