Has anyone experienced any underbead cracking or delamination of the finished bore done with hard wire? Im assuming doing a cut prior to buildup to keep the finish out of the heat affected zone.In my world of welding and fabricating hard wire has always been for 1/4" and under ,gauge metal,tanks and cab type stuff. Always used flux core with co2 for anything structural or repairs. So welding on heavy sections that require line boring seems a contradictory practice. I know its now done all the time, im just curious as to the long term end result.I think bore welders are an awsome invention after years of 7018 buildup . I plan to buy one or create one if i get ambitious, but i h dont do that much line boring these days.
