Background
The vacuum degree is an important parameter for measuring the vacuum performance of the vacuum arc-extinguishing chamber, and in order to keep the vacuum arc-extinguishing chamber in good vacuum degree in long-term use, a getter needs to be welded on a pipe part before sealing and exhausting in the manufacturing process of the vacuum arc-extinguishing chamber. At present, getter used for welding in a vacuum arc extinguish chamber is mainly divided into two types: a strip-shaped getter and a rectangular sheet-shaped getter. According to the shape of the getter, the positions and the number of welding points are different when the getter is welded in the vacuum arc extinguish chamber pipe. In order to ensure stable and reliable welding quality, a plurality of welding points are formed at different positions of the edge of the strip-shaped long-strip getter, and a plurality of welding points are formed at the corners of the rectangle by the rectangular sheet-shaped getter, so that each getter is smoothly and firmly welded on a part. The vacuum arc-extinguishing chambers with different structures and volumes have different quantities of the getter required to be welded according to performance requirements, and the greater the quantity of the getter, the greater the quantity of welding points, so that the welding work efficiency is low. There is therefore a need for improvements.
