Description
Technical field
The utility model relates to technical field of welding equipment, specifically a kind of titanium welds argon gas protective cover.
Background technique
Titanium is applied to aviation and navigates because of outstanding advantages of density is small, intensity is high, thermal coefficient is low, corrosion resistance is strong
It, petrochemical industry, electric power, the fields such as sea water desalination.Titanium or titanium alloy is very active non-ferrous metal, as the temperature rises shape
It can change, titanium about starts to absorb hydrogen at 250 DEG C or so, generates TiH2；Oxygen is absorbed since 400 DEG C, is generated TiO, is made
Material plasticity significantly reduces；The absorbed nitrogen since 600 DEG C forms brittle TiN.After these gases are absorbed, directly affect
The welding quality of titanium.Titanium and titanium are expensive, reprocess after there is welding defect and are not easy success, and titanium plate may be reported
It is useless, cause the waste of raw material.It needs to protect weld seam in the welding process.In titanium weld job, generally require
Two people's work compounds, a people carry out the welding in gap in front, another people needs hand-held pipe to spray argon gas to weld seam
Protected, argon gas will appear during sprinkling sprinkling it is irregular, welding quality unstable is caused on direct percussion weld surface
Problem.
Utility model content
The purpose of the utility model is to provide a kind of titaniums to weld argon gas protective cover, to solve to weld in titanium welding process
Stitch unstable quality, time-consuming problem.
To solve the above problems, technical solution adopted in the utility model are as follows:
A kind of titanium welding argon gas protective cover, it includes the pyramid type cover of bottom end opening, and the top of cover is provided with
Argon inlet pipe, the bottom of air inlet pipe are provided with the distributor of bottom opening, and distributor has been evenly distributed in the upper surface several overflowing discharge orifices, point
Silk screen layer is provided with below cloth device；Be provided with welding gun fixture on the front side wall of cover, the lower part of welding gun fixture be with before welding gun
The compatible conical base of shape is held, is provided with nozzle on the bottom surface of pedestal.
Preferably, the diameter of the overflow hole is 0.8-1.2mm, and the distance between adjacent two hole is 3.5-6mm.
Preferably, the cover, air inlet pipe, distributor, silk screen layer and nozzle are prepared by copper, aluminium or ag material.
When titanium welds argon gas protective cover applied to titanium welding, comprising the following steps:
Step 1: cover is placed in above welded workpiece, argon inlet pipe is opened, argon gas is from distributor upper surface
It is uniformly entered in cover in overflow hole, and by the quadratic distribution of silk screen layer, argon gas forms turbulent flow, sprays to weld seam；
Step 2: welding gun is clamped on welding gun fixture, welding gun is opened, mobile welding, temperature are carried out to welded workpiece
Welding position higher than 300 DEG C or more all shrouds within the protection scope of cover, and argon gas is deposited in the bottom of cover, attachment
In face of weld, weld seam is protected.
The purity of the argon gas is 99.99%.
The cover of titanium welding argon gas protective cover described in the utility model can be designed according to the shape and width of weld seam
Different size.
The utility model has the following beneficial effects:
(1) in use, argon gas passes through the overflow hole of distributor upper surface and dividing twice for silk screen to the utility model
Cloth forms turbulent flow, is uniformly distributed in welding region, is effectively protected that weld seam is not oxidized, and postwelding product surface color is most
For for silvery white, minority is golden yellow, the welding quality of product is improved, welding requirements is met；
(2) the utility model is simple for structure, deft design, and welding gun is clamped in the front of cover, benefit while welding
Argon gas protection is carried out to high-temperature soldering region with argon gas, the welding and protection of weld seam, time saving province can be realized in an operating personnel
Power.
