ABSTRACT:
A self-positioning scarfing apparatus includes a plurality of sensing wheels and scarfing tools, each sensing wheel and scarfing tool defining an operative set mounted on a common support and biased by a biasing device, such as a spring assembly or hydraulic cylinder, into engagement with an elongated weld on a workpiece. One operative set is mounted on each end of a yoke, which is in turn mounted for movement relative to the workpiece. In one embodiment, the yoke is mounted for pivotal movement with respect to the workpiece. In an alternate embodiment, a positioning wheel is mounted in the yoke for engagement with the workpiece, and the yoke is mounted for biased reciprocation to a hydraulic cylinder or spring assembly. Apparatus identical to that just described is positioned on the opposite side of the workpiece for scarfing the opposite side.
