Abstract
A scarfing apparatus for removing a weld bead from a tube being produced by a continuous method wherein the tube enters one end of a rotatable hollow spindle which supports a tool bit. The tool bit has an arcuate shape having a segment which extends 180.degree. or less about the periphery of the tube. The spindle oscillates rotationally causing the tool bit to rock back and forth across the surface of the moving tube to remove the weld bead. The tool bit is formed of carbide steel containing tantalum, titanium and cobalt. The tool bit has a forward face portion and a bottom face portion which define a tooling edge at their intersection. The bottom face portion slopes upwardly at an angle of approximately 3.degree. to reduce friction on the tube. For use with carbon steel tubing, a bit is used having a forward face portion angled approximately 15.degree. from the vertical. For use with stainless steel or aluminized material, a bit is used having a forward face portion angled back approximately 21.degree. from the vertical. The forward face portion is smoothed to no rougher than approximately 12-16 microinches to enhance chip flow. The bottom face portion is smoothed to no rougher th…
