Abstract
A zirconate metal welding lateral protection device is characterized by setting a lateral protection structure which is divided form a welding torch. The lateral protection structure is respectively arranged at the two sides of the molten pool at the position of the nozzle of the welding torch with a lateral gas hood with an opening facing to the side where a welding seam is arranged by following the direction of the welding seam; the lateral gas hood is internally provided with an airflow conductor which follows the direction of the welding seam and is communicated with a gas source pipe; the side wall of the airflow conductor is cut with airflow through holes. The utility model has the advantages of simple operation style, good protection effect and effectively enhancing welding efficiency and quality.
Description
Technical field:
The utility model is related to the device that the metal solder process provides inert gas shielding, a kind of zirconium metal solder protective device of more specifically saying so.
Background technology:
Zirconium is a precious metal, and good opposing corrosive nature is arranged under deep-etching chemical medium condition.Zirconium equipment is widely used in chemical industries such as formic acid, acetic acid.But; zirconium metal solder difficulty is big; one of them is in the process of welding zirconium metal; when temperature surpasses 300 ℃; its welding region will be used highly purified argon shield; if high temperature zirconium metal directly contacts with air, zirconium can absorb harmful elements such as airborne oxygen, nitrogen, causes zirconium Metal Mechanic Property and decay resistance sharply to descend.In welding process, on the one hand, need protect for the molten pool metal of torch neck position; On the other hand, still be in metal in the high temperature, comprise that weld seam and mother metal all need to protect for the welding gun back.At present, for the former, be to utilize the gas of torch neck self to implement protection, for the latter, the method that is adopted be at welding gun the rear, be positioned on the position while welding, be inconjunction with one with welding gun and drag cover by what moving ahead of welding gun directly dragged.Welding gun move drive following closely drag cover, make the relevant position in time obtain dragging the protection of cover.But; in the practical operation; because the zirconium metal is active especially; weak heat-dissipating drags cover to need enough length can reach the effect of protection thus, causes the workman inconvenient greatly in operation like this; welding efficiency is low; usually behind the weld seam of welding centimeter length more than 20, must stop welding, wait for that heat radiation fully.Moreover, in case drag cover and welding gun to disconnect, the weld zone high-temperature metal very easily is subjected to air pollution.
The utility model content:
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of mode of operation easy, implement protection effective, can effectively improve welding efficiency, improve the zirconium metal solder side protective device of welding quality.
The technical scheme that the utility model technical solution problem is adopted is:
The design feature of the utility model zirconium metal solder side protective device is to be provided with the side of welding gun split to protect structure; side protection structure is in the both sides that are positioned at molten bath, torch neck position; trend along weld seam; opening is set all towards the sidepiece gas hood of weld seam place one side respectively; what setting was communicated with the source of the gas pipe in the sidepiece gas hood walks airflow duct upwards along weld seam, offers the air-flow through hole on the sidewall of airflow duct.
Design feature of the present utility model also is:
On the opening of described sidepiece gas hood, separation net is set.
Air-flow through hole on the described airflow duct sidewall has two rows, one row be level towards weld seam, another row is that oblique below is towards weld seam.
End at described sidepiece gas hood is provided with end plate, and on end plate, it is positioned on the base angle of weld seam one side the base angle opening.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the protection of the utility model side is provided with the welding gun split, does not rely on dragging of welding gun, is convenient to operation, reduces labour intensity.
2, the utility model side protection is independent of welding gun and moves separately, thereby enough length can be arranged, so that weld can be protected fully, can the continuous welding operation, and the protection zone is big, and the effect of protection significantly improves.
3, the protection of the utility model side is positioned at the both sides in molten bath, torch neck position, and welding gun moves freely between the protection of two sides, the problem of disconnection can not occur protecting, guarantees welding quality.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model user mode schematic diagram.
Number in the figure: 1 end plate, 2 base angle openings, 3 separation nets, 4 sidepiece gas hoods, 5 airflow ducts, 6 source of the gas pipes, 7 welding guns, 8 back of the body protective covers, 9 zirconium sheet metals, 10 argon arc welding machines, 11 air accumulators, 12 welding wires.
Below, in conjunction with the accompanying drawings the utility model is further described by the specific embodiment:
The specific embodiment:
Referring to Fig. 1, Fig. 2; side protection structure with the welding gun split is set; side protection structure is in the both sides that are positioned at molten bath, torch neck position; trend along weld seam; opening is set all towards the sidepiece gas hood 4 of weld seam place one side respectively; what setting was communicated with source of the gas pipe 6 in the sidepiece gas hood 4 walks airflow duct 5 upwards along weld seam, offers the air-flow through hole on the sidewall of airflow duct 5.
Relative set in concrete the enforcement also comprises:
On the opening of sidepiece gas hood 4, separation net 3 is set, for can be high temperature resistant, separation net 3 be a material with the stainless steel, can also the thin copper wire net further be set at the internal layer of separation net.Being provided with of separation net 3 and its internal layer thin copper wire net is beneficial to the stable of protection gas.
Shown in Figure 2, the air-flow through hole that air-flow is led on 5 sidewalls has two rows, a row be level towards weld seam, another row is that oblique below is towards weld seam, so that protective gas is ejected into the high-temperature metal zone that needs protection from the side and the bottom of protective device.
In the end of sidepiece gas hood 4, end plate 1 is set, on end plate 1, it is positioned on the base angle of weld seam one side base angle opening 2, and base angle opening 2 has the effect of drainage, guides protection gas the surface of protected sheet material into.
Referring to Fig. 2; during operation; the utility model is placed on etc. on zirconium sheet metal 9 grooves to be welded, the freely-movable between the sidepiece gas hood 4 of both sides of welding gun 7 and welding wire 12, protective gas is ejected into the high-temperature metal zone that needs protection from the side and the bottom of sidepiece gas hood; implement protection; shown in Figure 2, after the side protection, carry on the back protective cover 8 accordingly and be provided with routinely; the source of the gas of argon arc welding machine 10, side protection source of the gas and back of the body protection source of the gas are gas of the same race, are taken from same air accumulator 11.
