Description

Welding torch location apparatus of automatic welding machine {Welding torch location apparatus of auto-welder}

The present invention relates to a welding torch height adjusting device of the automatic welding machine, and more particularly, to adjust the position of the welding torch in the automatic welding machine back and forth and up and down so that the tip of the welding torch can be easily fitted to the point to be welded. It relates to a welding torch height adjusting device of the automatic welding machine.

In general, welding refers to a jointing method in which a member heated to such a degree that the welded part is in a molten state or a molten state or a member in a normal temperature state is brought into contact with each other and applied under pressure. In other words, joining two metals together to make one is different from mechanical joints using screws or rivets. In general, welding joints cannot be disassembled. In addition, there is a method of interposing and joining other heated metals between metals to be joined, which is also included in welding in a broad sense. Since it is necessary to heat-melt the base material and the additive to weld, there are various heating methods.

As the heat source for welding as described above, gas, arc, electricity, resistance heat, frictional heat and the like are used. In the case of gas welding, oxygen-acetylene gas is used, and in the case of arc welding, a metal arc, a carbon arc, or the like is used. The term welding is mainly used for joining metals, but recent international standards organizations include joining non-metallic industrial materials such as plastic ceramics.

On the other hand, welding work can be divided into manual work and automatic work. In manual work, both parts of the welding part are different depending on the level of skill of the operator, and it is common to show a lot of difference in product quality. Therefore, an automatic welding machine has been developed and used to maintain a constant welding quality regardless of the skill of the operator.

The automatic welding machine as described above is mainly used for automatically welding a longitudinal reinforcing member called a longi to a hull abacus. This automatic welding machine has the effect of improving the working environment, work efficiency and labor costs due to the generation of many harmful gases during welding.
