Highly-efficient, energy-saving and environmentally-friendly manufacturing method of metal ceramic X ray tube

Abstract

The invention provides a highly-efficient, energy-saving and environmentally-friendly manufacturing method of a metal ceramic X ray tube. All parts are processed and manufactured at first, and then cleaned and assembled. The manufacturing method is characterized in that during the assembling, AgGu28 soldering flux sheets or rings are arranged in 10 to-be-welded welding places of a part, and titanium molybdenum getter is arranged in the cathode of a metal ceramic X ray tube; the assembled metal ceramic X ray tubes are vertically arranged in a material rack then sent into a vacuum welding furnace, vacuumized, heated to 650-750 DEG C, kept warm for 10-12 hours, heated to 800 DEG C and kept warm for 7-10 minutes until the welding materials are fused, so soldering and sealing are finished; a cooling system of the vacuum welding furnace is started, temperature is reduced to 60 DEG C in 4-6 hours, vacummization is stopped, and the welding materials are taken out of the furnace; and degassing, vacuum exhausting and welding for the materials are finished at a time, then performing the stress test for 8 hours, and at last qualified products are examined and put in storage. According to the invention, problems of low efficiency, insecurity, severe environmental pollution and high energy consumption of the current manufacturing technique are solved.

Description

technical field [0001] The invention relates to the production technology of industrial testing equipment, in particular to a high-efficiency, energy-saving and environment-friendly manufacturing method of a cermet X-ray tube. Background technique [0002] The metal ceramic X-ray tube is the core component of the industrial flaw detector, and the welding part in its processing technology is the key process of the metal ceramic X-ray tube, which directly affects the quality and qualification rate of the product. The traditional processing technology is: processing raw materials into parts→cleaning→assembly→application of hydrogen brazing furnace for welding of individual parts→heating up to about 600°C in a special exhaust table for vacuuming→shooting and degassing (above 800°C) → Sophisticated test → Qualified products are put into storage. The problems existing in the traditional process are: 1. Single welding and vacuuming operation, the production efficiency is low; 2. T...
