Description
Technical field
The utility model is related to a kind of titanium alloy welding protection device.
Background technology
It is well known that in welding process, gaseous impurity pollution easily causes welding point brittle, with temperature rising its
Absorbed nitrogen, the ability of oxygen also substantially rise therewith；Weld seam oxygen content rises, and the tensile strength and hardness of weld seam substantially rise, and
Plastic property of weld bead is decreased obviously, and weld seam becomes fragile because of the pollution of oxygen；Nitrogen high temperature fluent metal solubility with oxygen partial pressure increase and
Increase, influence of the nitrogen to weld strength, hardness, plasticity is more more notable than oxygen, that is to say, that the pollution embrittling effect of nitrogen is than oxygen more
For strong, influence of the nitrogen to weld seam is mainly the influence of On Impact Toughness, and nitrogen content increases, and the impact flexibility of weld seam is significantly dropped
It is low；In order to ensure the quality of welding point, prevent gaseous impurity from polluting, when industrial welding is carried out, often allow welding gun to form gas
Body protective layer, and the gas blanket that existing welding gun is formed can only protect welding pool not by air pollution, for having coagulated
Gu and it is in weld seam and its heat affected area then unprotect effect of the condition of high temperature.
The property of titanium alloy chemical element is active, in welding process, the weld seam high-temperature area after welding pool and fusion
Metal be easy to be chemically reacted with nitrogen, oxygen, the hydrogen etc. in air, cause seriously to reduce the mechanical property of welded seam area,
The welding titanium alloy under normal air environment, preferable protecting effect is extremely difficult to using conventional protection technique；It is main at present
Improved by two methods：1. it is to be welded under vacuum conditions, for example, carries out argon arc welding or electron beam in a vacuum chamber
Weldering；2. it is to be welded under atmospheric environment, by adjusting the shield gas flow rate of welding gun, expands the covering model of protective gas
Enclose, reduce speed of welding, welding protection effect is reached using small weld procedure specification measure.
Welded using vacuum environment, it is necessary to vacuum chamber and pumped vacuum systems, although protecting effect is good, but is welded into
This height, the welding job deadline is long, while the volume of vacuum chamber is not easy to match with the size of weldment, causes welding cost
The problems such as under rising or low production efficiency；Though second method can play obstruct air, postwelding titanium alloy high-temperature metal is prevented
The effect of oxidation nitridation, but protective gas is shorter with the time of bead contact, and protective gas is unable to substantially uniformity covering weldering
Seam, easily causes weldquality decline, and production efficiency is low if speed of welding is reduced.
The content of the invention
