I won't ever do any again, I will buy Staz and be done with it
The weld does indeed create the seal, but if properly welded it does not have to be done in one pass. We bevel the weld-in rings pretty good when we install a set and then tack them good in 4-8 areas. Then we weld in 2-3" at a time at 3-6-9-12, go on to another wheel and repeat through the other three wheels. When you get back to the first one start your weld about 1/4" from the first weld and backweld about 1/8" into it and then do the 2-3" forward weld and repeat to all welds. Fully weld over all tacks as you go.
The trick is the backwelding so it is like one continuous weld and seals correctly. Also, cleaning the wheel VERY WELL in the heat-affected area before welding is CRITICAL. We clean all of the powdercoat/paint within 1" of where we will be welding in all directions. The coating/painting will wick towards the heat and cause porosity if not cleaned well enough.
