Lincoln recommends using Sulfur for sealing up a cast iron weld. Where can I buy stick sulfur?
In the Lincoln Arc welding manual, written in the 50's or 60's (they still sell it) they talk about using stick sulfur to seal up a weld while its still hot(not while welding) to make it water tight.
Would the weld not be watertight anyway?
Hi Snowcat, thanks for that information, interesting, I will test this theory after new year and do an X-Ray of the joint and check the mechanical properties. Depending what type of cast Iron you use, as you know there is quite a range, for this exercise I will use an exhaust manifold. if nothing else it will be interesting dont you think. I might just learn something new. by the way, we [oldies] work in some funny ways LOL.
and was shown some cringe worthy tricks to use heat destortion on thick plate to an advantage..
