Question:

Titanium tube welding process should pay attention to what?

Titanium tube welding process should pay attention to what?

Answer:

Titanium and its alloys in the high temperature, titanium and titanium alloy absorb a lot of oxygen, hydrogen and other gases and brittle thermal conductivity is small, brittle
At high temperatures, titanium and titanium alloy absorb a lot of oxygen, hydrogen and other gases and brittle
Thermal conductivity is small, welding with rigid fixed to prevent deformation, post-weld annealing to eliminate stress. When used to prevent rigid deformation, welding annealing to eliminate stress
Annealing needs to be carried out under vacuum or argon protection, heating temperature of 550-650oC, under the thermostat under the heating temperature, constant temperature 1-4h
