a m8 asked me to weld a water intake off his boat today, it was in bad shape a block of rust. the inner pipe had two 2p size holes on the throat bend so could not reach with tig or mig and i assumed stick would be to harsh .
he cut a section off the outer tube off thinking we could weld it back on later and the inside tube is like paper so i tried tig with silicone bronze, cleaned as best as he could but struggling to get a decent ground, when we did it was blowing holes at 18amps
dropped to 15 and it was not melting rod properly. the contamination getting dragged back in was a pain as well.
would that muggy weld stuff work or is he best off just biting the bullet and scrapping it.
after 3 hours of messing about i had to admit defeat but wasted a load of 1.6mm silicone bronze and argon, was thinking of getting some 2,4mm but where do you draw the line, but to buy the new fitting is £850
set up, rtech 161 running at 18-25 amps dc, 1.6 2% thoriated tungsten, 1.6mm silicone bronze filler
