my project over the weekend
built this turbo hot side out of 304ss for my 72 el camino. its a 6 liter lq4 engine from a 2500 suburban.
the exh manifolds must be cast steel because the schedule 10 stainless welded fine to it with a 309 rod. not the prettiest welds but i back purged it got no sugaring and penetration seems to be decent.
the rest of the piping is 16 gauge 304ss which i back purged also,and used 308 rod. except if the gaps were good i used no rod. welds not the best looking but i back purged these also. i think my biggest problem was i couldnt see well. i was welding at 40 amps and my hood was to dark. i will be looking for a better one.
i used the 210 ext at 40 amps and used foot pedal. 3/32 lanthiated on exh manifolds and 1/16 lanthiated on piping.
any tips to help my welds look more acceptable would be appreciated.
