Abstract
The utility model relates to an immersed gas shielded welding device, comprising a gas-tight external housing for filling with shielding gas. The gas shielded welding in the prior art is open gas shielded welding, the workpiece to be welded is exposed to the air, the shielding gas injects on the surface of the workpiece through the nozzle of a welding torch and then merges into the air. The utility model is characterized in that the external housing (1) is a sealing housing with a transparency window, and a welding torch (3) is arranged inside the gas-tight external housing which is connected with a welding glove (2).The utility model is applied to the welding field in industry.
Description
Technical field:
The utility model relates to a kind of formula gas-shielded welding device that soaks.
Background technology:
The welding of gas shield at present all is open type gas shield welding, and promptly welded part is exposed in the air, and protective gas is sprayed on surface of the work by the welding gun mouth, incorporates in the air.There are two problems in open type gas shield welding, and the one, protective gas can't reclaim, too waste, the 2nd, the backing gas of workpiece solder side can't be protected, and causes the back side oxidized, can not reach the purpose of protection fully.
Summary of the invention:
The purpose of this utility model provides a kind of back side of workpiece solder side and workpiece solder side that makes and is effectively protected, and that saves protective gas soaks the formula gas-shielded welding device.
Above-mentioned purpose realizes by following technical scheme:
Soak the formula gas-shielded welding device, its composition comprises: fill air-locked outer cover of protective gas, described outer cover is the seal closure that has transparency window, in described air-locked outer cover welding gun is housed, and described air-locked outer cover connects with welding gloves.
Soak the formula gas-shielded welding device, have the fixed station of soldered thing in the described outer cover.
The beneficial effects of the utility model:
1. fill protective gas in the outer cover of this product, welded piece is immersed in the protective gas, welding quality has been improved all in the environment of protective gas in the two sides that makes the welding object.
2. protective gas is controlled in the outer cover of welding usefulness, and can reuses, significantly reduced the use amount of protective gas, reduced the cost of welding.
3. this product can make the welding quality of workpiece obviously improve, and really reaches workpiece in welding engineering, is among the protection of protective gas always, and is not oxidized.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
The specific embodiment:
Embodiment 1:
Soak the formula gas-shielded welding device, immerse air-locked outer cover 1 of protective gas, described outer cover is the seal closure that has transparency window, in described air-locked outer cover welding gun 3 is housed, and described air-locked outer cover connects with welding gloves 2.
Soak the formula gas-shielded welding device, have the fixed station of soldered thing in the described outer cover.Welded part 4 is fixed on the fixed station.
Application example:
The inner bag major part of electric heater is welded with stainless steel; be to adopt open type gas shield welding in welding process; the solder side of gas shield is not oxidized; and the back side of its solder side is the inner surface weld of inner bag; protective gas can't be protected; cause the inner surface commissure of inner bag oxidized; the average water leakage ratio that causes the water heater stainless steel inner container is up to more than 10%; the area of poor water mass is up to more than 90%, and many water heaters manufacturing enterprise abandons producing the electric heater of stainless steel inner container.
Formula gas shield welding is soaked in employing; earlier argon gas is placed in air-locked outer cover; the water heater stainless steel inner container is put into outer cover; the staff is with gloves to take welding gun preparation, charges into argon gas, welds; the back side of its solder side is that the commissure of the inner surface of inner bag has argon shield all the time; make the diaphragm of commissure on stainless steel inner container surface not destroyed, the average water leakage ratio that makes the water heater stainless steel inner container is less than 0.1%, and the use amount of argon gas is less than 5% of the open type welding.This product had both improved the welding quality of stainless steel inner container, had reduced welding cost again significantly.
Claims (2)
1. one kind is soaked the formula gas-shielded welding device; its composition comprises: the air-locked outer cover that fills protective gas; it is characterized in that: described outer cover is the seal closure that has transparency window, in described air-locked outer cover welding gun is housed, and described air-locked outer cover connects with welding gloves.
2. the formula gas-shielded welding device that soaks according to claim 1 is characterized in that: the fixed station that has soldered thing in the described outer cover.
