Abstract

The invention discloses a molybdenum tube electrode and stainless steel electrode support welding device and a welding process. The molybdenum tube electrode and stainless steel electrode support welding device comprises a bottom plate; a molybdenum tube electrode tray tool is arranged on the bottom plate; a plurality of molybdenum tube electrodes are placed on the top of the molybdenum tube electrode tray tool in parallel at intervals; the two ends of each molybdenum tube electrode extend out of the molybdenum tube electrode tray tool; stainless steel electrode support pressing tools are symmetrically arranged on the two sides of the molybdenum tube electrode tray tool; the stainless steel electrode support pressing tools comprise a lower pressing tool used for pressing the bottom of a stainless steel electrode support on the bottom plate and an upper pressing tool used for pressing the top of the stainless steel electrode support on the two sides of the molybdenum tube electrodes; and the welding process comprises the steps of winding an Ag54Cu21Pd25 brazing wire on to-be-welded pipe orifices of the molybdenum pipe electrodes and the like. According to the molybdenum tube electrode and stainless steel electrode support welding device, the bonding strength and the sealing performance of the molybdenum tube electrodes and the stainless steel electrode support can be ensured; the flow of the internal cooling water path can be ensured; and the high-energy particle beam extraction capability of an ion source can be further improved.

Description

technical field [0001] The invention relates to the field of welding manufacturing technology, in particular to a welding device and a welding process supported by a molybdenum tube electrode and a stainless steel electrode. Background technique [0002] With the development of accelerator research, the energy of particle beams is getting higher and higher, and the requirements for water pressure and flow of internal cooling water circuits have also increased accordingly. The welding points of grid-shaped electrode molybdenum tubes and stainless steel electrode supports are the weak points of the entire internal cooling water circuit. Publication No. CN101920367A, the patent titled a Welding Process of Molybdenum Tubes and Stainless Steel Hollow Parts discloses a welding process for molybdenum tubes and stainless steel hollow parts, in which the welding surfaces of the molybdenum tubes and stainless steel hollow parts to be welded are plated with metal After the transition ...
