Titanium wire carburizing surface treatment
Titanium wire and carbon form a kind of stable carbide with higher hardness. The growth of the carbonized layer between titanium and carbon is determined by the diffusion rate of titanium in the carbonized layer.

The solubility of carbon in titanium is small, at 850X: a total of 0.3%, and it drops to about 0.1% B at 600C. Due to the low solubility of carbon in titanium, basically only through the titanium carbide layer and its lower fork Deposit a layer to achieve the purpose of surface hardening. Carburization must be carried out under the condition of deoxygenation, because the powder suitable for the common carburization of steel faces the surface of carbon monoxide or oxygen-containing carbon monoxide and the hardness of the surface layer reaches 2700MPa and 8500MPa, and it is easy to peel off.

Precautions for using titanium welding wire:

(1) Construction workers and welders should wear clean white gauze gloves (no cotton gloves are allowed).

(2) It is strictly forbidden to touch and touch iron objects by hand in the treated welding area.

(3) Welding work should be performed indoors as much as possible, and the ambient wind speed should be ≤0.5m / s

to avoid being affected by the wind.

(4) When welding, short arc welding should be used as much as possible, with a small welding heat input, and the

angle between the nozzle and the weldment should be 70-80 degrees.

(5) When the butt pipe is positioned and welded, its butt gap is generally about 0.5mm.

(6) Each welding seam should be completed as much as possible. The welding seams must be connected. Before

welding,

the joints should be cleaned. The length of the welding meat overlap is 10-15mm.

(7) When welding, the welding torch should not swing left and right, and the melting end of the welding wire must

not move

out of the gas protection area.

(8) Gas should be supplied in advance when welding arc initiation. Welding torch cannot be lifted immediately when

arc is extinguished. Gas supply should be delayed until the temperature drops below 250 ℃.

(9) The distance between the gas shield and the welding torch should be short, and the gap in contact with the pipe

wall should be small. When performing butt welding of pipes, in order to meet the requirements of single-sided welding

and double-sided forming, the welding is performed in two times: one for back-sealing welding (without filler materials

when back-sealing), and the other for forming welding. In multi-layer welding, the previous bead must be completely

cooled before the next bead is welded.

(10) Welding must be completely cleaned of surface impurities such as oil, rust, and moisture.
(11) To prevent the surface temperature of the bead from excessive oxidation during welding, a tail cover must be

added to enhance the protection effect.

Production Process of titanium wire:

Titanium sponge→compacting electrodes→melting→forging→bar billets→hot rolling→cold draw→titanium wires

Surface quality: high precision, good finish, no oxidation color, no cracks, peeling, thorns, marks and inclusions. Minor

local scratches, abrasions, spots and pits that do not exceed the allowable deviation of the wire diameter are allowed.
