Brian (TD&H) used to do spray welding at his fab shop. A very cool process!I thought it was interesting to watch how this is done.
I binged watch Abom all weekend.
They did submerged arc on our rolls to build them up at the steel mill that I worked at, that was interesting to see.When I worked at the steel foundry they had a company come and spray weld up bearing journals on some of the mill rolls that were undersize.
No welder here, was looking at an alternative. JB may be an option, but was looking for something better without spending $$$ and havind a huge learning curve.@larrybl ,
It's called flame welding "Brazing" and it's similar to soldering. You can for weld just about any non-ferrous or ferrous material in closing aluminum. It's really art when you figure out what preheat and post heat you need along with what flux and filler rod you need to use.
As far as seat pans go, I've used good ole metal wire coat hangers and even 6011 1/16" welding rods with the flux still on them.
Remember when repairing cracks always drill a hole at the end of each crack before repairing. This will prevent the crack from spreading.Talking about welding, I saw an add somewhere about a welding stick that can be used with a regular blow torch, almost like soldering.. If this is true, I would like to try it on some seat pan cracks.
