Description
Technical field
The present invention relates to welding field, particularly a kind of ventilation type automatic welding gun of special small-caliber deep hole bottom built-up welding.
Background technology
A kind of economic and quick process of the built-up welding as material surface modifying, more and more widely applied to each
During the manufacture of industry part is repaired.Built-up welding is that the performances such as one layer of deposition is wear-resisting, anti-corrosion, heat-resisting are carried out at the surface of workpiece or edge
The welding procedure of metal level, to enhancing product performance, reducing cost has significant economic benefit for built-up welding.
Less than 30mm small-caliber deep holes bottom along the hard alloy sealing surface that side built-up welding 8-10mm is wide, 6-8mm is high, at present
What is used is essentially all manual electric arc welding.Because as used automatic welding, the structure of welding gun is by the body of a gun, wire feed and several portions of water cooling
Divide and form, diameter itself is larger, and deep hole welding gun minimum diameter is 28mm at present, can not be completed in below 30mm small-caliber deep holes
Automatic welding.
The content of the invention
For overcome the deficiencies in the prior art, it is automatic that the present invention provides a kind of ventilation type in the built-up welding of special small-caliber deep hole bottom
Welding gun is welded, the cooling system of Butt welding gun is improved, by using protection gas cooling welding tool while being protected to molten bath in hole
To reduce welding gun profile, realize and complete automatic welding in special small-caliber deep hole bottom.
A kind of ventilation type automatic welding gun of bottom built-up welding of the present invention, including the body of a gun, the body of a gun external diameter are not more than 15mm,
The body of a gun lower semisection favours upper semisection, and the body of a gun lower semisection forms 5-10 ゜ angles, the top of the body of a gun with upper semisection
Side is provided with gas feed, and the gas passage being connected with gas feed is provided with the body of a gun.
Further, center is provided with ignition tip in the body of a gun.
Specifically, the ignition tip is through the body of a gun, and stretch out the top and bottom of the body of a gun.
Further, the quantity of the gas passage is two, is respectively provided at the both sides of ignition tip.
Specifically, the gas feed is cooling gas and protection gas import.
Specifically, the gas passage is cooling gas and protection gas passage.
Further, screw thread is provided with the top of the body of a gun, side is provided with screw thread close to the top.
The beneficial effects of the invention are as follows：The existing welding gun in the built-up welding of small-caliber deep hole bottom is essentially all the hand of use
Work welding, the water-cooling system of the automatic welding gun of routine is changed to by protecting gas while entering to molten bath by this ventilation type automatic welding gun
And can Butt welding gun is cooled down simultaneously for row protection, so as to reduce the profile of welding gun, solves to be difficult to reality in special small-caliber deep hole bottom
The problem of existing automatic welding, and with simple in construction, being convenient to use and carry, the advantages of automaticity is high.
