AWS a5.16/AMSE SFA 5.16 ErTi-2 ErTi-5 ErTi-7 tig titanium welding
wire rod
Titanium welding wire has excellent welding process performance,
beautiful weld formation, and its welded metals
have excellent comprehensive mechanical properties.
Mainly used for welding of titanium-based alloys.

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.
