Embodiment Construction

[0062] First, according to Figure 1 to Figure 4 , the first embodiment of the welding device of the present invention will be described in detail.

[0063] The welding device of the present invention generally includes: a welding torch 1, which imparts heat energy to the welding site; a welding wire supply unit 2, which supplies filler wire F to the welding site; and a tracking unit 3, which controls the movement trajectory of the welding torch 1 and the welding wire supply unit 2 Follow the welding line Y; the tracking unit 3 has a contact 30A or 30B, and the contact 30A or 30B is arranged in a manner that can advance and retreat or can rotate, and elastically contacts the joint object W; the filler wire is supplied to the welding site by the welding wire supply unit 2 F, and the heat energy is given by the welding torch 1, and at the same time, the contact 30A or 30B of the tracking unit 3 is elastically contacted with the object W to be joined, so that the welding torch 1 ...

Abstract

Welding equipment includes a torch for irradiating a laser beam B, wire feeding means 2 for feeding a filler wire F, and tracking means 3 for controlling the moving tracks of the torch 1 and the wire feeding means 2 so as to make the moving tracks follow a welding line Y. The tracking means 3 has a contactor 30A provided so as to be advanceable / retractable for making contact with a joint object W resiliently. The torch and the wire feeding means 2 are moved so as to follow the welding line Y by touching the contactor 30A of the tracking means 3 resiliently to the joint object W while feeding the filler wire F to a welding portion and irradiating that portion with the laser beam B, thereby joining the joint objects W.

Description

technical field [0001] The present invention relates to a welding device and a welding method, and more particularly relates to a welding torch which imparts heat energy to a welding site and a welding wire supply unit which supplies filler wire to the welding site, the welding wire is supplied to the welding site through the welding wire supply unit, and the welding wire is supplied by the welding torch. A welding device and a welding method in which the thermal energy of the welding part is moved along the welding line to join the joint objects with each other. [0002] Here, the welding referred to herein refers to "brazing" in which the base material is not melted as much as possible, in addition to the case where the base material is melted. Background technique [0003] In order to join objects to be joined to each other, a technique of welding by supplying a filler wire from a wire supply unit and applying heat energy to a welded portion by a welding torch has been wi...
