Abstract
The invention provides a kind of electro-beam welding joint structure, this structure is a kind of to eliminate welding line joint seam gap, add the electro-beam welding joint structure of Anti-welding spatter technology groove.Its structure includes: outer cylinder body, Anti-welding spatter technology groove, technique seam, inner barrel.Outer cylinder body uses banjo fixing butt jointing structure with inner barrel part, and joint is backed with Anti-welding spatter technology groove, transfers by two semicircles are smooth in technology groove two ends.It is backed with welding procedure seam, leaves enough gaps the most uniform the processing of seam between 4 air discharge ducts, and outer cylinder body and inner barrel technique seam radial direction.This structure can effectively prevent the electro-beam welding joint structure that fatigue crack produces.
Description
Technical field: the invention is that one eliminates welding line joint seam gap, adds
The electro-beam welding joint structure of Anti-welding spatter technology groove.
Background technology: certain type aero-engine air conduit assembly have employed electron beam Welder
Skill, electron beam weld typically requires that back of weld seam is machined removal by postwelding, but by
Limiting in design of part, edge weld back process seam postwelding cannot be removed, and weld width is not
Completely seam width can be covered, cause postwelding technique stop portion to leave gap, long-term at part
It is easily generated fatigue crack at technique seam gap during use, has a strong impact on the use longevity of part
Life.
Summary of the invention: the purpose of the invention is to provide one can effectively prevent fatigue crack
The electro-beam welding joint structure produced.
The invention is achieved through the following technical solutions: this joint design is mainly by following
Several parts form: outer cylinder body, Anti-welding spatter technology groove, technique seam, inner barrel.Outward
Cylinder uses banjo fixing butt jointing structure with inner barrel part, and joint is backed with Anti-welding spatter technique
Groove, transfers by two semicircles are smooth in technology groove two ends.It is backed with welding procedure seam,
Process 4 air discharge ducts seam is the most uniform, and outer cylinder body is with inner barrel technique only
Enough gaps are left between mouth radial direction.
The advantage of the invention is: this welded joint structure eliminates former joint design back side work
Skill seam, the technique seam gap that after eliminating electron beam welding, the joint back side exists, weld simultaneously
The joint back side increases Anti-welding spatter technology groove, it is possible to completely spatter thing is enclosed in work
In skill groove cavity, it is to avoid splash flies into inner chamber and wounds part inwall.This joint design improves
Welding line joint intensity, it is possible to the generation of fatigue crack during effectively preventing part from using.
Technical scheme
A kind of welded joint structure is provided, including: outer cylinder body, inner barrel, Anti-welding spatter work
Skill groove；Outer cylinder body is coaxially arranged with inner barrel, and outer cylinder body has the banjo fixing butt jointing extended internally,
Inner barrel has outward extending banjo fixing butt jointing, inside and outside cylinder banjo fixing butt jointing all include work
Skill seam and joint to be welded, the end face of the technique seam of inside and outside cylinder relatively and leaves gap,
The end face docking of the joint to be welded of inside and outside cylinder；
The technique seam of the technique seam of inner barrel and joint to be welded and outer cylinder body and joint to be welded
Collectively form Anti-welding spatter technology groove.
The most uniform on the technique seam of inner barrel or outer cylinder body process 4 rows
Air drain.
Further, described gap is not less than 0.2mm.

Detailed description of the invention
Concrete structure includes: outer cylinder body, inner barrel, Anti-welding spatter technology groove；Outer cylinder body with
Inner barrel is coaxially arranged, and outer cylinder body has the banjo fixing butt jointing extended internally, inner barrel have to
The banjo fixing butt jointing of outer extension, inside and outside cylinder banjo fixing butt jointing all include technique seam and to be welded
Joint, the end face of the technique seam of inside and outside cylinder relatively and leaves gap, inside and outside cylinder
Joint to be welded end face docking；
The technique seam of the technique seam of inner barrel and joint to be welded and outer cylinder body and joint to be welded
Collectively form Anti-welding spatter technology groove；
The most uniform on the technique seam of inner barrel or outer cylinder body process 4 rows
Air drain；
Described gap is not less than 0.2mm.
During welding:
(1) outer cylinder body is put in place with the assembling of inner barrel part, welding point end face, connect
Head unfitness of butt joint is in the range of standard-required.
(2) part gas in vacuum chamber, Anti-welding spatter technology groove is by outward
Gap and air discharge duct between cylinder and inner barrel part process seam radial direction are discharged.
(3) selecting welding parameter to carry out electron beam welding, docking soldering tip fuses completely.
(4) welding seam is not punctured by line, and spatter thing is completely enclosed within Anti-welding spatter work
In skill groove, thus play the effect of protection part inwall.
Claims (3)
