Embodiment Construction

[0037] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0038] Such as Figure 1 to Figure 3 As shown, the gas shielded welding contact tip equipped with a shaft sleeve of the present invention is a copper contact tip 4, which is installed on the receiving welding wire 3 at a predetermined speed and according to the contact tip generated between the welding wire 3 and the base material 2. The front end of the gas shielded welding welding machine 1 that forms the molten pool by welding the arc, and transmits the welding current to the welding wire 3 to guide the molten pool, including: a nozzle body 10 made of copper, which is drilled for installation on the welding machine 1 There is a through hole 11; a cylindrical rod-shaped electric connection part 20 is integrally connected to the front of the nozzle main body 10; a bushing 30 is installed on the front end of the electric connection part 20; a fr...

Abstract

The invention discloses a Gas Metal-arc (GMA) welding contact tip having a bushing made of a copper material. The invention is characterized in that the GMA welding contact tip is installed on a front end of a GMA welding machine which receives welding wires at a predetermined speed and forms a molten according to the welding arc generated between the contact tip and parent metals, and welding current is transmitted to the welding wires so as to guide the bath. The GMA welding contact tip includes a copper tip main body installed on the welding machine; an energization connection part integrally connected to the front of the tip main body in a conducting manner, the energization connection part being narrower than the periphery of the tip main body (10); the cylindrical bushing made of materials stronger than the copper and installed in the front of the energization connection part, and preventing burn back caused by the wielding arc and the diameter expansion of the tip; and a front reinforcement mouth around the energization connection part and the periphery of the bushing.

Description

technical field [0001] The present invention relates to a contact tip (ContactTip) for gas shielded welding (gasmetalarcwelding) equipped with a bushing for prolonging its service life, and more particularly to a contact tip for gas shielded welding with a bushing that prevents the contact tip from being caused by an arc. The welding spatter (weldspatter) caused by the arc generated during welding can be attached to the tip of the welding tip to burn back (burnback), or by preventing the expansion of the diameter of the nozzle outlet caused by the wear of the wire supply during welding, the use of the welding tip can be greatly extended. life, and can greatly reduce the purchase cost caused by the damage of the welding tip, and reduce the thermal deformation caused by heat by ensuring the formation of a small space inside the front-end reinforcement tip and the welding tip, thereby prolonging the service time, and through Strengthen the strength of the welding tip made of copp...
