The weld is there doing 2 purposes iirc.
1 obviously it's joining the two items
2 the reason it covers such an area it's protecting the material from corrosion as ami said.
Personally I'd join it with the appropriate material and clad over it in inconel 625.
My final post of multi runs i do loves a challenge but im bored of them now hopefully stick welding this weekend but ill see what u guys think of this run its just a 10fw
It's hard to see the bottum. The top looks nice n clean but low amprage. Technice looks spot on.try playing around a bit with your amps. Vs your first post you improved greatly. Well done m8.
28 volts 290 ish amps its within my wps but I'm using aircooled setup and not a nice one it will do it but the torch gets super hot ill play around in the 35 volts 300 + amps see what u think mate wont be till next week sometime now
