Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic electrogas welding apparatus,

The present invention relates to an automatic electromaggassing apparatus capable of being transversely or intermittently bent, and more particularly, it is possible to improve the structure so that an automatic electromagnet welding can be carried out in a vertical direction as needed and a 'lateral direction' And more particularly, to a transversely or bidirectionally automatic electrogas welding apparatus.

In the process of manufacturing various industrial devices and machines, they are subjected to a process of combining metals. There are various methods for bonding these metals, for example, screws, rivets, welding, fitting, and the like.

Among them, welding is a method in which heat and pressure are applied to the same kind or different kinds of metal materials so as to be bonded directly between solid bodies, and there are a fusion method and a pressure welding method.

Fused welding, commonly called welding, is a method of heating and melting a metal material at a joint to re-arrange the atomic bonds of two different materials, such as arc welding, gas welding, and thermite welding. Since the joint surface on which welding is performed tends to be easily retracted including impurities, it is preferable to use a deoxidizer to remove oxygen from the joint or a flux that promotes dissolution so that the metal is well mixed, or an inert or reducing gas May be used to prevent oxidation. The good and the bad of the welding result are called the weldability, and all of the base material, the welding rod and the working conditions which are the subject of the welding are affected. Recently, a new welding technique such as an electroslag welding method using resistance heat of a slag used for welding a very thick plate or an electron-beam method capable of welding a material having a high melting point has been developed . Ultrasonic welding for applying ultrasonic vibration, laser welding for precise welding and cutting, and the like.

In addition, coated metal (arc metal) arc welding, submerged arc welding, inert gas welding and the like are available. Coated metal arc welding is the most common method of welding to be welded, that is, welding with arc heat generated by applying a voltage between the base material and the coated electrode.

The welding rod melts and mixes with the molten metal of the base material, filling the gap between the base material and the base material, and solidifies to become a weld metal. Submerged arc welding is a method in which a long unsealed electrode is supplied at a constant speed and the weld is melted by the heat of arc generated between the end and the base metal to automatically weld.

One of the areas where welding equipment is widely applied is welding equipment or welding equipment. In the manufacturing process of ships, vertical welding, horizontal welding, and slope welding are often performed for welding the sub-assembled blocks and blocks. In welding, the basic structure of a welding device for welding two welding members (steel plates) against each other is to generate an arc through the welding torch from the welding site and to melt the welding material at the same time as the gap between the front bead and the welding member To form a back bead.

The above welding is performed when CO2 welding is performed. When the welding member (steel plate) is thick, the depth to which the molten metal is to be filled is deepened. Accordingly, the welder repeatedly welds several times on the bead formed first To complete the welding process.

However, repeated welding by manual welding requires a long welding time, and the rate of occurrence of defects is high according to the degree of proficiency of a welder. There is a limit to the flow of bead and high current use by multi-pass welding.

Accordingly, an automatic welding apparatus has been developed to improve the workability of such manual welding and to produce a constant weld bead. There has been proposed a so-called " side-by-side " method in which the automatic welding apparatus moves in the horizontal direction as well as the "
