Description

[0001] DESCRIPTION [0002] JIG UNIT CLAMPING MULTI-WELDMENT FOR ELECTRON-BEAM WELDING [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clamp jig for multi-arc welding for electron beam welding, and more particularly, to a clamp jig for multiple- To a multi-welded clamp jig for electron beam welding that fixes a weld to minimize the uniformity and deformation of the weld.

Generally, when welding a metal requiring precision, an electron beam welding method using an electron beam is widely used. Electron beam welding is a method of accelerating electrons emitted from a cathode in a high vacuum to a high voltage, colliding with a welding material, and welding with energy.

Since such an electron beam welding method is performed in a high vacuum, it is easy to weld metal which is easy to react with the atmosphere. Further, since the electron beam can be narrowed by a lens to focus energy, welding of high melting point metals such as zirconium, tungsten and molybdenum is possible .

In addition, since electron beam welding has a small amount of welding heat (鎔 insertion heat) as compared with other welding methods, there is very little deformation such as misalignment of welding. Since the width of the welding portion is narrow, precise welding is possible, Therefore, it has various advantages such as high speed welding of thick plate. Therefore, electron beam welding machines are widely used throughout the industry.

A typical electron beam welder is composed of a jig and a fixture, and a weld is loaded on the jig to perform welding by the electron beam. At this time, the sliding plate on which the jig is lifted can freely move in the X-axis and Y-axis directions on a plane with respect to the base plate under the jig. Therefore, usually, a separate jig is placed on the sliding plate, thereby performing electron beam welding.

However, in the electron beam welding machine, a process for high vacuum (hereinafter, referred to as a vacuum exhaust process) is necessarily required for the welding work, and this vacuum exhaust process occupies about 70% of the entire electron beam welding operation. As a result, the time required for actual electron beam welding is only about 10% of the total welding work, and therefore, the efficiency of electron beam welding is inevitably low. In order to solve this problem, in the past, devices for reducing the vacuum exhausting time such as the volume and capacity of the vacuum pump have been utilized. However, since these devices are not only expensive but also require a vacuum evacuation process for each welding material, I have to fall.

Accordingly, there is a need for a jig capable of clamping a plurality of welds in a vacuum chamber and welding the same to an evacuation process and welding in a vacuum chamber.
