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.
Summary of the invention
The object of the present invention is to provide the guard methods of a kind of titanium welding argon gas protective cover and titanium soldered, with solution
Certainly unstable, the time-consuming problem of weldquality in titanium welding process.
To solve the above problems, the technical solution used in the present invention 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 gas
Air 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, distributor
Lower section be provided with silk screen layer；Welding gun fixture is provided on the front side wall of cover, the lower part of welding gun fixture is and welding gun front end shape
Shape compatible conical base 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.
A kind of guard method of titanium soldered, this process employs above-mentioned titaniums to weld argon gas protective cover, it is wrapped
Include following steps:
Step 1: cover is placed in above welded workpiece, argon inlet pipe, overflow of the argon gas from distributor upper surface are opened
It is uniformly entered in cover in 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 is carried out to welded workpiece, temperature is higher than
300 DEG C or more of welding position all shrouds within the protection scope of cover, and argon gas is deposited in the bottom of cover, is attached to weldering
Seam surface protects weld seam.
The purity of the argon gas is 99.99%.
The cover of titanium welding argon gas protective cover of the present invention can design different according to the shape and width of weld seam
Specification.
The invention has the benefit that
(1) in use, argon gas is formed disorderly the present invention by the distribution twice of the overflow hole and silk screen of distributor upper surface
Stream, is uniformly distributed in welding region, is effectively protected that weld seam is not oxidized, and postwelding product surface color is mostly for silvery white
Color, minority are golden yellow, improve the welding quality of product, meet welding requirements；
(2) structure of the invention is succinct, deft design, and welding gun is clamped in the front of cover, utilizes argon gas pair while welding
High-temperature soldering region carries out argon gas protection, and the welding and protection of weld seam can be realized in an operating personnel, time saving and energy saving.
