Scarfing method and apparatus.

摘要

Apparatus is disclosed for removing excess weld material from elongated welds in which one or more cutters (46) are moved by hydraulic cylinders (30) into precise positions in proximity to the article (16, 18) having the welds to maintain the desired uniform thickness of the welds. The operation of the hydraulic cylinders (30) is controlled by tracer control valves (50) having operating elements (90) engaged by members (61) connected to sensing rollers (62) which engage the article (16, 18) as it is moved past the sensing rollers (62). The positions of the rollers (62) and the cutters (46) may be separately adjustable to accommodate articles (16, 18) of various sizes.
