Description
Technical field
The present invention relates to a kind of welding guns, especially TIG welding guns.
Background technology
The protection weldering of non-melt pole inert gas tungsten electrode（Tungsten Inert Gas Welding, TIG）Welding gun（Following letter
Claim TIG welding guns）Effect is clamping tungsten electrode, conduction welding current and conveying and sprays protective gas.Existing water-cooled TIG welds welding gun
Structure is as shown in Figure 1.Structure is mainly by tungsten electrode 1, ceramic nozzle 2, air guide casing 3, terminal clamp 4, gun body 5, electrode cap 6,
Air inlet pipe 7, cooling water pipe 8 control switch 9, and torch handle 10 is constituted.When welding, when electric current is more than among argon atmosphere
Realize that gun body cools down using cooling water pipe 8 when 150A, air inlet pipe 7, which transmits gas to ceramic nozzle 2, makes ejection protective gas,
Play the role of air-isolation protection molten bath in welding process.4 one end of terminal clamp, which is connected by conducting wire with power supply, conducts welding
Electric current, the other end are connected with tungsten electrode 1.Arc heat is generated after energization between tungsten electrode and weldment to be welded.
With the fast development of China's intelligence manufacture industry, the wall thickness dimension of large scale structure is increasing, such as 1000 MW grades
Nuclear-power reactor, pressure vessel wall thickness is up to 250 mm；And the steam turbine low-pressure welded disc turbine rotor of nuclear power, thickness are also up to 200
Mm or more.Backing welding is carried out using Fig. 1 welding guns, as traditional TIG welding guns, is designed using coaxial gas shielded, gun body 5 is located at
Among ceramic nozzle 2, when welding, tungsten grade and molten bath are among argon atmosphere.In order to ensure that welding gun has good thermal diffusivity
And realize the accessibility of welding gun, it is necessary to open Y type grooves and be welded, the angle of groove needs 70 °, and weld seam is wide and deep, not only fills out
The phenomenon that filling amount of metal increase, wlding and energy consumption increase, and welding efficiency declines, while will appear side wall incomplete fusion, influences
The quality of weld seam.Obviously traditional welding method cannot meet the needs of these components making.
Invention content
The present invention overcomes the deficiencies in the prior art, provides and a kind of can guarantee that welding gun welds under narrow and deep groove and still has
There is good thermal diffusivity and realize the accessibility of welding gun, wlding and energy consumption consumption are reduced, and welding efficiency and weldquality improve
Narrow gap TIG welding guns.

Parallel cooling tube, which tilts, to be extended, to preferably close to welding gun bottom, protect tungsten electrode, improve protecting effect.
4. liang left gas hood of the adjustable connection of collets difference and torch body and right gas hood and torch body.Because of gas
Body is there are flow field and has stickiness, only can just form laminar flow under certain condition, and after welding gun is using double gas hoods, when welding will
There are two strands of gases.When two bursts of gas flow rate sizes or direction difference, it is easy to form turbulent flow when meeting.Thus it is designed so that
Left and right gas hood relative position is adjustable, can adjust the flow direction of two strands of air-flows, forms laminar flow protective gas, is advantageous to improve
Protecting effect improves welding quality.
5. torch body is equipped with the connecting pin being connected with collets, connecting pin is equipped with to the left gas hood of correspondence or right gas
The strip limit hole that direction extends is covered, collets bottom end is equipped with the limited block for being slidably inserted in limit hole, and collets
Being equipped with mating can be fixed on the threaded connector of limit hole, so as to easily adjust two gas hoods and tungsten electrode away from
From, namely convenient for two strands of gases it is transferred to best protection position, collets are limited by the cooperation of limited block and limit hole,
It can better ensure that the relative position of left and right gas hood and torch body.
6. the water inlet of left gas hood air inlet, right gas hood air inlet and cooling structure is all provided with airtight sealed structure, then
It can guarantee good leakproofness so that welding gun of the invention further integrates torch body, water cooling, airtight, using more
It is convenient.
