发明名称 Welder's mismatch gauge
摘要 A welder's gauge for detecting mismatches between two members having a gap therebetween and which are to be welded together comprises a pair of side-by-side elongate body members guided for relative axial movements. Feelers project from the body members and terminate in feet that can be passed through the gap following which they can be turned to span the gap and engage the surfaces of the two members to be welded together. Differences in the levels of the two surfaces are indicated by indicia on the body members. The feelers are removable from the respective body members for repair or replacement.
