Abstract
The invention provides a repair welding device of weld joints in a cavity. The repair welding device of the weld joints in the cavity can solve the problem that an existing repair welding device cannot carry out reliable repair welding on poor welds in the cavity, reduces scrapped products, and reduces production cost. The repair welding device of the weld joints in the cavity comprises a tungsten inert gas arc welding (TIG) welding torch. The repair welding device of the weld joints in the cavity is characterized by further comprising a photographic device and a display screen. A grad handle of the TIG welding torch is provided with an extension rod, the side of a ceramic protection cover of the TIG welding torch is provided with the photographic device, and the photographic device is in electronic control connection with the display screen.
Description
Technical field
The present invention relates to the repairing welding field of interior die cavity weld seam, be specially the repair welding equipment of die cavity inside weld.
Background technology
the member that has interior die cavity weld seam for hollow stationary blade etc., because the welding gun of the repair welding equipment (TIG argon tungsten-arc welding) of routine exists rifle head volume large, the reasons such as inconvenient operation, add upper impression long and narrow, volume is little, internal light is not enough, cause the repair welding welding gun to be not easy to stretch into die cavity inside, even and the repair welding welding gun can stretch into die cavity inside, also because inner dark, volume is narrow and small can't judge defective locations, and be difficult to grasp the welding gun motion conditions in process of patch weld, therefore when there is weld defect in die cavity inside weld member, be difficult to repair and cause scrapping.In Fig. 1,9 for treating the die cavity weld seam of repair welding.
Summary of the invention
For the problems referred to above, the invention provides the repair welding equipment of die cavity inside weld, it can solve existing repair welding equipment can't carry out to poor weld in die cavity the problem of reliable repair welding, thereby reduces scrapping of product, reduces production costs.
Its technical scheme is such; it comprises the TIG welding gun; it is characterized in that: it also comprises camera head and display screen; the lever of described TIG welding gun is installed on extension rod; the ceramic protection cover avris of described TIG welding gun is equipped with described camera head, and described camera head and described display screen electricly connect.
It is further characterized in that:
Described camera head is installed on front side or the rear side of the ceramic protection cover of described TIG welding gun, and the angle β between described camera head and welding gun tungsten electrode axis direction is at 20 °～70 °, between the tungsten electrode of described camera head and described welding gun is top is 10mm～60mm apart from d, and it is top that the image pickup scope of described camera head covers described tungsten electrode;
Described camera head is any in camera, endoscope head.
adopt repair welding equipment of the present invention, its beneficial effect is: the lever of its TIG welding gun is installed on extension rod, the ceramic protection cover avris of TIG welding gun also is equipped with camera head, and camera head and display unit electricly connect, can be easily stretch in die cavity welding gun tungsten electrode is top by extension rod, the camera head of welding gun ceramic protection cover avris can be taken the weld seam situation in die cavity and shown by display screen simultaneously, operating personnel can be shown according to display screen die cavity inside weld situation carry out the repair welding operation, it is simple in structure, easy to use, can be widely used in having the repairing work of the inside weld of cavity structure.
