Description
More particularly, the present invention relates to a positioner-type tag welding apparatus in which a rectangular shaped wire roving material is fed, welded, deformed into an arc-shaped wire roughening material, and fused and welded on a turntable on a pipe-shaped base material.
In general, welding means welding two or more objects or materials into a molten or semi-molten state, and then joining the materials (welding rod and wire) to the welding process. Various welding methods are used depending on the type and thickness of the material.
There are two types of welding, called base metal, or indirect welding by adding a welding rod to a welding part of an object, which has been developed in various ways. Among them, special welding TIG welding (TUNGSTEN INERT GAS) welding, which is an arc welding method, is used for the welding of atomic power and aircraft products. It is a method to precisely weld high quality products by the applicable welding method.
TIG (Tungsten Inert Gas) welding is a manual welding process in which welders manually manipulate the torch and the grooved material according to the welding method, and semi-automatic welding in which only the torch is manually operated And automatic welding that automatically operates the welding machine.
Conventionally, a conventional tig welding apparatus has been mainly used to weld a round wire-like joining material on a cross-sectional shape and to weld it on a base material. In the case of using the round wire sealant on the cross section, the welding efficiency is lowered due to the circular cross-sectional structure. Therefore, a technique of fusing the arc-shaped wire sealant on the base material to improve the welding efficiency is required.
Particularly, in the case of inner diameter raising welding of pipes, nozzles, etc., a technique capable of maximizing the welding efficiency is required rather than the welding of the conventional single-sided circular wire fusing material.
In order to solve the above-mentioned problems, the present invention proposes a positioner-type tig welding apparatus in which a rectangular shaped wire roving material is fed and welded to a pipe-shaped base material fixed by a positioner unit and deformed by an arc-shaped wire roughening material.

The calibration guide unit is provided with a plurality of guide holes, wherein the curvature of the bottom surface of the rear guide hole formed on the rear side is larger than the curvature of the bottom surface of the inlet guide hole formed on the entrance side of the calibration guide unit.
Further, in one example, the lower shaping rollers of each of the first and second shaping roller units each have a projecting portion vertically protruding from both sides of the recess in a cross section, and each upper shaping roller has a horizontal end portion formed on both sides of the projecting portion in a cross- , The protruding portion protrudes to the horizontal end side and limits the pulling range in the lateral direction of the wire sealant interposed between the concave portion and the convex portion on the first and second shaping roller units.
