Background technology
Aviation part CF-34 combustion box is by rear housing by electro-beam welding method, combustion chamber front housing, export orientation vane diffuser is together with inner outlet guide vane flange welding, it is the weld seam of full penetration type, minimum weld width requires at 2.1-2.9mm, need higher power could meet minimum weld width requirement, there is larger splashing at the postwelding weld parts back side, pincers are repaiied workman and are repeatedly polished and could remove, remove splash later surface still remaining have non-ly see vestige, the non-constant of surface quality.The assembly particularly formed after export orientation vane diffuser and inner outlet guide vane flange welding, due to structure, polishing region is narrow, is difficult to splashing to clean out.
Summary of the invention
In order to solve the technical problem of above-mentioned existence; the invention provides a kind of electron beam welding guard method; it can be applied in the coating protective material of piece surface; piece surface is protected when electron beam welding; namely meet initial workpiece development and batch need of production of on-the-spot part, greatly improve quality and the operating efficiency of part.
The technical solution used in the present invention is as follows:
A kind of electron beam welding guard method of the present invention, comprises following processing step:
(1) parts processed surface: clear up protection surface, the surface after cleaning is without greasy dirt, exotic;
(2) prepare protective material: before use, ensure that the viscosity of protective material is within the scope of 15 ± 5S; Or in process and after using a period of time, add toluene, the mixture of dimethylbenzene or toluene or dimethylbenzene dilutes protective material as diluent, ensure that the viscosity of protective material is within the scope of 15 ± 5S, and then carry out the stirring of-1 hour half an hour;
(3) protective material is applied: coating weld seam to be welded lock basal surface non-solder region being carried out to protective material before weld parts, the distance of coating zone distance weld seam is 3-5 millimeter, uniformity is wanted in the coating of weld root locality protection material, coverage rate is 100%, then dry 5-10 carries out second time coating again after dividing in atmosphere, until need protect surface all uniform fold protective materials;
(4) solidification of protective material: after completing the coating needing protection zone, by part dry 1-1.5 hour in atmosphere, right fed to boiler solidifies 1-2 hour in drying baker, and solidification temperature is 80 ± 5 DEG C, then carries out the welding of part;
(5) welding of part: weld by electro-beam welding process code;
(6) removal of protective material: the removal part welded being carried out protective material, the part after solidification can remove coating material by hand, ensures that coating material is removed complete, thorough.
Further, described protective material is anti-splash coating protection agent TURCOFORMMASK522, and adopt the mode of leaching or brushing to be coated in piece surface, its solids content is 34.5%, and viscosity is 15 ± 5S, and after solidification, the bond strength of rete reaches more than 900psi.
Beneficial effect of the present invention:
The present invention, by the research of electron beam welding splatter guard material and progress, makes part finally meet the technical requirement of design drawing and associated documents, and can greatly improve quality and the operating efficiency of part, reduce cost.
Accompanying drawing explanation
Fig. 1 is electron beam welding of the present invention protection part schematic diagram.
In figure: 1. rectified diffusion device assembly, protection zone I of splashing 2., 3. casing leading portion, 4. casing back segment, protection zone II of splashing 5., protection zone III of splashing 6., arrow is designated as electronic beam current direction.
