Vacuum coating machine for welding requirements

What are the requirements for vacuum coating machine for welding? Vacuum coating machine for welding requirements? This article points 6 details the vacuum coating machine for welding requirements.
, 1, design the structure of the weld joint must penetration, should avoid to produce harmful space gather filth. Welding is correct and the side of the weld on the vacuum to depth of fusion welding, can ...form a dead space, mostly wrong welding is blocked some space between the two weld, inside there are gas storage.
2, should be a good welding seam, to avoid two welding cause dead space and cannot leak detection.
Because 3, weld strength needs to be two sides welding, internal weld should not leak, for reasons of leakage in the outer weld shall set up drilling plug.
4, if the container shall be welded structure, internal weld should not be straight, in order to let the gas easily from any groove, and the structure of weld should not be crossed with seal weld.
5, welding components should be designed to make the largest number of weld can test respectively in the manufacturing phase, and to correct before final assembly.
6, welding seal (air), the maximum allowable leakage rate on the weld length of about 10-7 Pa, m3 (s. m). If the leakage rate is higher, should wear off of the welding, until the parent metal, welding again, remember that don't produce in the original place of leakage welding twice, because the repair welding is not only difficult to plug hole leakage, easy to produce stress make weld instead to create new cracks.
