Abstract

The utility model relates to novel welding equipment. The utility model has the main technique that an argon arc welding machine, an argon gas bottle and a cooling water tank are respectively connected with an argon arc welding gun through a conduit. The argon arc welding gun is positioned in the front end of an upper supporting cover, a protective gas pipe and a cooling copper pipe are arranged in the upper supporting cover and a lower groove of a worktable, and the back surface of the opposite surface of the protective gas pipe and a bevel is drilled with uniform small holes. A thin copper screen seals an upper protective gas pipe and an upper cooling copper pipe in the upper supporting cover. An upper cooling copper plates is arranged on a contacting position of the lower edge outside the upper supporting cover and a weldment, and a lower cooling copper plate is arranged at the contacting position of the lower groove of the worktable and the weldment. The equipment can weld the large weldment and the small weldment, and welding seams can have stable and favorable mechanical properties.

Description

Novel welding equipment

The utility model relates to welding equipment, and is particularly relevant with the welding equipment of welding refractory metal niobium, tantalum.

The method of existing welding niobium, tantalum has two kinds, and a kind of is to carry out in being full of the casing of inert gas, and this method only is applicable to small-scale member.Another kind is to carry out inert gas-shielded arc welding in air; this method is applicable to large-scale component; the measure of inert gas shielding is the positive holder cover that adopts of groove; groove is adopted at the back side; inert gas is delivered in pop-up cover and the low groove by conduit; pop-up cover and low groove and welding gun are synchronized with the movement, and the non-oxidizability of weld seam is bad when welding in this way, and the weld seam mechanical performance of welding out is stable inadequately.

The purpose of this utility model provides a kind of novel welding equipment that can weld large and small member and can effectively guarantee the weld seam good mechanical properties.

Major technique structure of the present utility model is as follows:

Argon arc welding machine; argon bottle links to each other with argon-arc welding gun by conduit respectively with cooling water tank; argon-arc welding gun is positioned at the front end inside of pop-up cover; protective gas pipe on the inner and upper of pop-up cover has; the back side of last protective gas pipe and groove opposite face is drilled with equally distributed aperture; below pop-up cover inside, cooling copper tube is housed; thin copper mesh will go up the protective gas pipe and last cooling copper tube is closed in the pop-up cover; outside bottom loads onto cooled copper with the weldment contact position at the pop-up cover; has the workbench low groove on the equipment lower body; the workbench low groove is relative with the weldment groove; workbench low groove inner and upper has following cooling copper tube; below, workbench low groove inside has following protective gas pipe; the back side of following protective gas pipe and groove opposite face is drilled with equally distributed aperture, and workbench low groove and weldment touching position are equipped with down cooled copper.

The utility model is compared its advantage with prior art and is, promptly can weld the stable favorable mechanical performance that big part can weld smallclothes again and can make the weld seam tool.

Concrete structure of the present utility model is provided by the following drawings.

Fig. 1 is a main TV structure cutaway view of the present utility model;

Fig. 2 is a plan structure cutaway view of the present utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

As Fig. 1; shown in 2; argon arc welding machine 1; argon bottle 2 links to each other with argon-arc welding gun 5 by conduit respectively with cooling water tank 3; argon-arc welding gun 5 is positioned at the front end inside of pop-up cover 4; protective gas pipe 6 on the inner and upper of pop-up cover 4 has; last protective gas pipe 6 is drilled with equally distributed aperture 16 with the back side of groove opposite face; below pop-up cover 4 inside, cooling copper tube 7 is housed; thin copper mesh 8 will go up protective gas pipe 6 and last cooling copper tube 7 is closed in the pop-up cover 4; 4 outside bottoms load onto cooled copper 9 with weldment 10 contact positions at the pop-up cover; has workbench low groove 13 on the equipment lower body 15; workbench low groove 13 is relative with weldment 10 grooves; workbench low groove 13 inner and upper have following cooling copper tube 14; workbench low groove 13 inner belows have following protective gas pipe 12; following protective gas pipe 12 is drilled with equally distributed aperture with the back side of groove opposite face, and workbench low groove 13 is equipped with down cooled copper 11 with weldment 10 touching positions.Feed cooling water in the cooling tube during equipment work; feed argon gas in the protective gas pipe; pop-up cover 4 is synchronized with the movement with argon-arc welding gun 5; because the timely while inert gas of cooling evenly jumps on the molten bath by protective gas pipe aperture; thereby realize the effective gas protection; the weld seam non-oxidizability strengthens like this, and the silvery white of light finally appears in face of weld.
