Description

Manual TIG Welding Welding Rod Feeder Support Mechanism {SUPPORT APPARATUS FOR MANUAL TIG WELDING OF WELDING ROD FEEDER}

The present invention relates to a manual TIG welding electrode feeding device support mechanism, and more specifically, a manual TIG welding electrode that supports the electrode feeding device as the feeding device support mechanism so that the electrode feeding device can be constantly moved toward the welding portion of the welding base material. It relates to a feeder support earth.

In general, joining metals requires accessing atoms of two metal surfaces that join to the extent that the bonding force between the atoms.

To this end, various welding methods have been developed in which a welding rod is added indirectly between two objects called a base material or a part of a welding part by welding. One of them is TIG (Tungestn Inert Gas Welding) welding.

The TIG welding method is used for products requiring high quality precision welding. Hereinafter, the TIG welding method will be briefly described.

The TIG welding method uses tungsten, which lasts for a long time even at a high temperature of about 3400 ° C, as an electrode and flows an inert gas around the electrode that does not react with other substances such as argon (Ar) and helium (He). It is the welding method which generates an arc between them, and fuses and fuses a filler metal and a base material with this arc heat.

Since the above TIG welding method is made in an inert atmosphere, there is no need for flux for welding, and high-quality inverter can be used as it is welded because there is almost no spatter generated by precise control of arc adopting high frequency inverter method. As it is possible to secure welding metals, it is recently used as a core welding method for nuclear power plants, petrochemical plant structures, and thin plate structures that require the integrity and precision welding of welds.

However, there is a disadvantage that the gas used is relatively expensive, and is easily affected by the wind, and the welding speed is slow. However, in recent years, the use of the TIG welding has been conventionally developed as a new TIG welding method is developed that overcomes the above disadvantages due to the improvement of technology. It is increasing significantly.

On the other hand, the TIG welding method can be roughly divided into semi-automatic welding, automatic welding, and manual welding.

Specifically, the filler metal used in welding generally uses a coil-shaped material as it is, so it is generally called a welding wire.

In welding work, the above welding wire should be kept close to the base material without interruption, and the arc should be kept constant. The automatic realization of this by the wire feeder is called semi-automatic welding. When an operation of automatically moving is accompanied, this is called automatic welding.

1 is a schematic perspective view showing a state in which the operator according to the conventional manual welding.

Unlike the semi-automatic and automatic welding as described above, manual welding, as shown in Figure 1, the operator (P) directly holding the welding torch (1) in one hand and the welding wire (2) in the other hand welding site (A ) How to weld.

This manual welding is carried out when the part of the base material which is not easy to be welded by automatic welding or the welded part by automatic welding is insufficiently welded.

However, in this case, the worker uses a rod-shaped welding wire having a length of about 1m, and the feeding speed of the welding wire is slowed down due to the hand feeding and feeding to the molten portion, thereby causing a problem in that the amount of welding per unit time is very low.

In addition, the operation of feeding the welding wire with one hand greatly increases the fatigue of the worker, adds an excessive force to the arm and shoulders of the worker to reduce the productivity of the worker and the risk of burns and safety accidents exist.

And since such manual welding requires a high level of skill due to many experiences, there is a shortage of manpower capable of smoothly performing welding.
