Therefore, need badly and find a kind of brand-new solution, it should possess the generation thoroughly avoiding workman to coordinate situation not in place, effectively ensures the welding quality of Thin-Wall Outer Casing cylindrical shell and mounting edge.
Summary of the invention
For prior art Problems existing, the invention provides Manual welding device and the method for a kind of Thin-Wall Outer Casing cylindrical shell and mounting edge, welding job no longer needs two people to coordinate, a people is only needed to complete welding job, thoroughly avoid the generation that workman coordinates situation not in place, effectively ensure that welding quality.
To achieve these goals, the present invention adopts following technical scheme: the Manual welding device of a kind of Thin-Wall Outer Casing cylindrical shell and mounting edge, comprise welding gun, protective cover, hollow bar, adapter and frame linking, described frame linking one end is fixedly connected on the rifle body of welding gun, and the frame linking other end is hinged on adapter; In the middle part of described adapter, offer pole installing hole, described hollow bar one end is positioned at pole installing hole, and the hollow bar other end is connected with protective cover; The centre bore of described hollow bar is set to passage, and passage one end is connected with argon gas source of the gas, the passage other end and protective cover intracavity inter-connection; The case mouth of described protective cover is corresponding with the back of weld of Thin-Wall Outer Casing cylindrical shell and mounting edge.
The case mouth place of described protective cover is provided with argon gas screens.
Described argon gas screens adopts nickel screen.
The first clamping screw is provided with between described hollow bar and adapter.
Described adapter and frame linking hinged place are provided with the second clamping screw.
The welding method of the Thin-Wall Outer Casing cylindrical shell described in employing and the Manual welding device of mounting edge, comprises the steps:
Step one: by Thin-Wall Outer Casing cylindrical shell together with mounting edge assembling and positioning, and tack welding in addition;
Step 2: welding gun and hollow bar are connected argon gas simultaneously, and argon flow amount is adjusted to setting value;
Step 3: the relative position and the angle that manually adjust hollow bar and frame linking, make the case mouth of protective cover be positioned at the back of weld of Thin-Wall Outer Casing cylindrical shell and mounting edge;
Step 4: manually adjust angle of welding gun, makes welding gun be in welding position;
Step 5: switch on power, carries out welding, and in welding process, protective cover together moves along with welding gun, protects weld seam not oxidized by the protective cover being full of argon gas.
Beneficial effect of the present invention:
Compared with prior art, welding job no longer needs two people to coordinate in the present invention, only needs a people to complete welding job, thoroughly avoids the generation that workman coordinates situation not in place, effectively ensure that welding quality.
