Is there anybody there with experience using Lincore 36LS self shielded fluxcore wire? When I put 1st hardfacing layer on E71T-1 underlayer, I’m getting “wormholes” porosity. But on second & third layer no problems at all. All time I used same parameters: voltage, stickout, etc. Cleanliness is not an issue. Any idea, what’s the problem?

Thanks

Maybe the problem is the underlayer? The couple of times I had wormholes I ran a stringer bead over the base metal. Just used build up rod, cant remember the type.Not sure why it worked. The other and not very consistant way was to use a corded stringer brush and really rough it up. Good luck those wandering beads can be a headache.
