Referring to Fig.1-3, a specific implementation mode of the invention includes rack 1, and 1 both ends of rack are connected with card by oil cylinder 2
The intermediate position of pawl 3, rack 1 is equipped with soldering sleeve 4, several induction coils 5, soldering sleeve 4 are laid in soldering sleeve 4
Inner surface be evenly arranged with several protection gas blowout stomatas 6, the side of rack 1 is provided with sliding rail 7, is slidably connected on sliding rail 7
There is glue filling nozzle 8, is connected by cylinder 9 between glue filling nozzle 8 and rack 1.Claw 3 includes pedestal 10, the edge axis of pedestal 10
Be connected to several outer snap arm 11, pedestal 10 is provided centrally with mounting hole 12, in mounting hole 12 activity be plugged with internal cutting ferrule 13.Outside
The medial surface of snap arm 11 is provided with idler wheel 14, and the axial direction of the axial direction and internal cutting ferrule 13 of idler wheel 14 is mutually perpendicular to.Glue filling nozzle 8 includes
Conical shell 15, the top of conical shell 15 are provided with the first plastic hole 16, and the side wall annular of conical shell 15 is placed with several
A second plastic hole 17.The axis angle of first plastic hole 16 and the second plastic hole 17 is 22 °, and the first plastic hole 16 goes out with second
The ratio between the internal diameter in glue hole 17 is 3:1.
A kind of above-mentioned welder for steel-cored aluminium strand repairing, includes the following steps：
A, steel-cored aluminium strand to be repaired is fixed using claw 3, position to be repaired is placed in soldering sleeve 4
