Abstract
Description
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.

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, .

And the pipe of the connection part is a flexible pipe capable of bending operation by a user.
And a welding wire guide for guiding movement of the wire supplied through the welding cable is further provided between the head body and the flexible tube.
The head housing and the pipe housing are insert injection-molded in a state in which the assembly including the head body, the welding wire guide, and the flexible pipe is connected to each other.
The connection part includes a flexible cofferx wave tube, an external insulation tube surrounding the flexible cofferx wave tube, an electric power connection tube provided for electrical connection inside the flexible coffer wave tube, And an inner insulating tube for insulation between the Schneafelex corrugated tubes.
According to the present invention, the head assembly includes a first conduit and a second conduit communicating with one side of the first conduit, wherein the gas or wire is supplied through the first conduit, and the electrode according to the welding method is selectively mounted on the second conduit .
According to the selected welding method, at least one of a gas diffuser, a nozzle, a welding tip, and an electrode collector is selectively installed in the second pipe so that the user can perform a CO 2 welding and a TIG welding as well as a torch body They can be easily combined and used.
In addition, in the present invention, by constructing the integrated welding torch by applying the above-described head assembly for welding torch, the electrode according to the welding method, the gas diffuser corresponding to the selected electrode and the nozzle, the shielding means, The welding method can be easily changed.

The tungsten electrode and the electrode The TIG welding can be performed by mounting the second nozzle to the second gas diffuser accommodating the collector. In the case of manual metal arc welding, a welding operation can be performed by mounting a welding rod to the electrode collector instead of the tungsten electrode and removing the nozzle.
In addition, the head assembly is formed so that the second channel is vertically penetrated, and the opened upper side is shielded by the shielding means, so that the gas leakage can be prevented while easily accommodating the relatively long electrode.
In addition, since the shielding means as described above can be selectively installed in a form that does not accommodate the electrode and accommodates the electrode according to the welding method, the user can easily perform the welding operation by changing the welding method .
In addition, in the present invention, since the head housing constituting the head assembly and the duct housing constituting the connecting portion are integrally formed, the gap between the head assembly and the connecting portion is sealed, and gas leakage can be prevented.
Therefore, according to the present invention, at least one of the gas diffuser, the nozzle, the welding tip, and the electrode collector mounted on the head assembly is replaced according to the selected welding method, unlike the conventional welding method in which each welding torch according to the welding method is purchased and used So that it is possible to easily switch the operation, thereby improving the workability and facilitating maintenance and storage.
In addition, according to the present invention, since a soluble connection portion is further provided between the head assembly and the cable connector, the integration angle can be changed according to the user's need, thereby facilitating the welding work.
