Flux Welded ?

Anyone have issues PC'ing over Flux welds?Got a frame to do and read that Flux welds trap gasses in the weld.

I haven't but I read somewhere about it. You are suppose to make sure the flux on the welds is cleaned off good before coating. I think they were suggesting a wire wheel on a die grinder. I can't remember where I read it though.

Re: Flux Welded ?

Is the frame virgin material ? what is the substrate material ? Weld splatter could be an issue as well as oils behind the welds....

I worry about weld expolsions, they can be difficult depending of the questions I asked..

Virgin is not a dirty word

The reason is:

no one wants to take the extra step of cleaning before they weld which creates problems. A plant in East TN, has oil come out of their welds in the cure oven due to lack of cleaning....I put an IR oven before the washer to raise the metal temperature and expand the metal, then she goes through the 5 stage washer

I have been messing around with some fluxed core wire in my mig and it coats just fine. I was going for a polished edge, so i ground the hell out of it, but i didnt outgas it. You want to make sure you get all of those oxides off of there for sure. I would say that wire wheel on the drill would do it well enough.
