I welded a Rumely 6 around the drain plug hole. It was extremely thin 1/4 to maybe 3/16". I welded as low temp (low power setting) as I could get the nickel rod to spark. I welded as fast as possible and tried too keep it coll. As it would get hot, the block started to sag away. Take your time and make short welds letting it cool between each. My weld has held now for over three years.Good luck!! Larry Renck
: I was wondering if anyone could give me some advise on welding a engine block. The block I am working on is a WC Allis Chalmers. It has a
: horizontal crack located to the left of the engine : serial # runnig towards the block drain. : I am planning on welding this with nickel rod with : the engine in place. (Just draining the coolant) : My plan is to preheat the area with a torch then weld 1/2 inch at a time then post heat to prevent the cast iron from cooling to fast and forming : finger cracks. I am wondering how thick this block : is in this area, does anyone know? Or does anyone : have some good advise or experience they would like to share with me.
