Description

A total welding torch

The present invention relates to a head assembly for a welding torch which can be applied to both CO ₂ arc welding, TIG arc welding and passive metal arc welding, and an integrated welding torch using the same.

Arc welding is the most widely used joining method currently used for joining metal materials by fusing welding using an arc as a heat source.

Generally, arc welding can be classified into carbon arc welding using carbon electrode and metal arc welding using metal electrode depending on the type of electrode used, and different types of welding can be performed depending on the respective welding method, cooling method, A welding operation is performed using a torch.

In particular, carbon arc welding is a method in which an arc is generated between a welding base material and a carbon electrode to melt an electrode. Metal arc welding generates an arc between electrodes made of the same kind of metal as the welding base material, Thereby bonding the base material. Accordingly, in the metal arc welding, since the continuous supply of the electrode consumed in the welding torch is required, the electrode portion having a shape different from that of the welding torch for the carbon arc welding is obtained.

Also, in case of welding method, Shield Metal Arc Welding (SMAW), which is most widely used at present, is used in the category of GMAW (Gas Metal Arc Welding) And is classified into CO ₂ , MIG, MAG, and Ar welding depending on the type of gas.

In addition, FCAW (Flux Cored Arc Welding) has a working principle such as GMAW, but it uses a self-protection method in which the flux is filled in the wire, And the welding torch having a structure different from that of the GMAW method is used.

That is, in the prior art, each welding torch corresponding to each welding method is used, and a water-cooled type and an air-cooled welding torch are also used separately according to the cooling method.

In addition, the welding torch may be classified into large, medium, and small types according to the length of the torch. In order to perform various welding operations, the user must purchase and use various welding torches according to the welding method, .

On the other hand, Korean Patent No. 10-1412374 entitled " Welding torch and its assembling method " discloses a technique for easily assembling and disassembling a contact tip, which frequently occurs during welding, without a separate tool.

Korean Patent Laid-Open Publication No. 10-2014-0078826 " Welding Torch " discloses a welding torch capable of easily separating a welding tip from a tip holder.

In other words, in the conventional technologies, the welding part is changed only according to the welding method, and the welding part is changed only by the welding method. I can not do it.
