Re: Visibility welding seams

There is a marking substance made by curv-o-mark not sure what its called but it actualy ignites when in contact with the arc. It is very usefull when it is hard to see the weld path. It gives you a very good indecator as you move along centering you on the weld.

Re: Welding cast to steel

Welding axle is complete. I bought Ni lincoln rod but it would not run worth a shit. I ended up welding it with 7018 an inch ir so at a time and jumping around quite a bit. It welded very nicely and with no cracking. I preheated at 350 and post heated down to room temp over 24 hours. Seems they may ...

Re: thinking about a career in welding

I agree with alot of whats been said. I started welding on a farm at fourteen and spent four years learning by mistakes and mentors. At 18 I went to vocational school and learned alot of the fundamentals on set up, speeds and metalergy. The classes would have baflled me and I would not have "co...

Re: Welding cast to steel

I was tacking evering thing in position with a 70XX wire and the tacks were cracking so I know it will not work well. I have seen alot of motor heads get away...

Re: welding cast to steel

Forgot to ask: Lincoln had broblems with NR211 being brittle and came out with NR212, which is a more ductile filler. Anyone had experience with using this on cast?
