Welding knuckle gussets ??

[skyhighZJ]

A friend of mine wants me to weld a front truss and knuckle gussets to his JK Dana 30. I am more than comfortable with the truss but what are the recommendations for mig wire to weld to the knuckles? Is preheating the cast required? Cooling blankets? Also I have 75/25 ARCO gas, will I need to use something different?

When I welded on a set I did a short pre heat with a torch. I didn't want to put too much heat into it because the ball joints were still in the knuckle.

Cast steel, make sure it's clean. heat it a little & burn it in.

I clean the "C", C clamp the gussets in place, stitch weld while alternating sides, keep clamps on and let them cool slowly.

Easy peasy to be honest.

Thank you all it has set me at ease.

yourhotdogguy was his old name...whats he going by these days? terry moorefield is his real life name.

he's full of this kind of knowledge, and for what ever reason, i sat through a talk he gave about welding on axles and a lifetime of experience. does he still frequent the boards?
