The present invention has following beneficial effect:
1, argon arc welding gun is penetrated in gas hood before welding, be full of after argon gas until gas hood, weld again under making welding gun welding wire all be in the protection of argon gas, can more effective welding pool and the weld seam that is in the condition of high temperature be protected.
2, the nozzle guard of argon-arc welding gun self is limited in scope, and in welding process, the molten bath cooled not yet completely can cool under the protection of gas hood, effective solution welding pool problem of oxidation.
3, when welding position leaves gas hood, metal has been cooled to less than 250 DEG C, this addresses the problem the absorption oxygen of the metal being in the condition of high temperature in titanium alloy welding process, hydrogen, nitrogen element problem, avoid the oxidizable problem very easily in the welding process of oxidized metal such as titanium alloy, ensure that the welding quality of titanium alloy.
4, the observation window (glass plate) of gas hood is placed in the top of gas hood, presents oblique angle state, can observe welding pool very easily in weld job process, be beneficial to the operation of operating personnel.
5, argon gas conduit has steam vent (in gas hood inner section), the direction of pore is towards gas hood top, and the argon gas entering gas hood by wireway in weld job process can cool the glass plate at top, prevents glass overheated.The air of gas hood inside can be discharged gas hood towards gas hood top by steam vent sooner, more thoroughly.
6, argon gas wireway is near the long side plate of gas hood, takes this kind of layout can not produce interference to sight line.
7, gas hood framework is welded by stainless steel material, makes gas hood possess certain rigidity.
