METHOD AND APPARATUS FOR SMOOTHING WELDED MEMBER

摘要

A smoothing method and a smoothing apparatus uses a belt grinding apparatus, including an endless grinding belt and a press pad that presses the grinding belt against a welded area, and uses this belt grinding apparatus in two different modes after obtaining information on heights of surfaces of two welded members along a weld bead of the two welded members. The first mode corresponds to a bead removing step in which the grinding belt is pressed against a welded area by the press pad to reduce the height of the weld bead. The next mode corresponds to a smoothing step in which the grinding belt presses against the welded area by the press pad while being made to move along the surfaces of the two welded members to smooth the welded area.

1. A welded area smoothing method for removing and smoothing a weld bead of two welded members, comprising:
a step of preparing a belt grinding apparatus, which includes an endless grinding belt and a press pad that presses said grinding belt against said welded area; a measuring step for detecting positions of heights of surfaces of said two welded members along said weld bead; a bead removing step for reducing a height of said weld bead by pressing said grinding belt against said welded area via said press pad while running said grinding belt using information on said positions of said heights of said surfaces of said two welded members that are detected in said measuring step; and a smoothing step for smoothing said welded area by pressing said grinding belt against said welded area via said press pad while running said grinding belt and moving said grinding belt along said surfaces of said two welded members.
