<P>PROBLEM TO BE SOLVED: To provide a following sensor for metal bar fillet welding, which rarely breaks down due to the heat from a welded portion, can detect distortion of the angular line of a fillet joint near a welding point, and can make the welding torch follow the angular line precisely. <P>SOLUTION: The following sensor for metal bar fillet welding is provided for detecting a welding line which is an angular line of a plurality of combined long plate materials. The following sensor includes: a sensor body; an arm base coupled to the sensor body such that the head thereof swings; a pair of contacts configured to travel in the longitudinal direction along a position crossing a welding point on a pair of plates composing the welding point; a support member in which the pair of contacts are fixed to tip ends of the biforked pair, and the rear end thereof is coupled to the arm base; and a welded line detector for detecting the swing direction and the angle of the arm base. <P>COPYRIGHT: (C)2012,JPO&INPIT |
