The protection of wlding makes wlding be melted into liquid on the base material to be welded and forms molten bath, make to be welded metal and wlding is reached by high current
To a kind of welding technique of metallurgical bonding, due to constantly serving argon gas in high-temperature fusion weld, prevent wlding from in air
Oxygen contact, to prevent the oxidation of wlding, avoid metal inclusion.
When practical operation, one piece of closure plate is respectively usually filled at two steel pipe both ends of docking, argon gas is inserted into one end wherein
Pipe, to steel filling steel pipes with argon, when steel pipe is long, needs the amount of applying argon gas larger, extremely wastes, while the time of applying argon gas
Also long, cause working efficiency to reduce.
Summary of the invention
The purpose of this utility model is exactly in order to solve existing argon gas-sealed device and need the amount of applying argon gas larger, very
The problem of waste, while the time of applying argon gas is also long, and working efficiency is caused to reduce provides a kind of for steel pipe argon arc welding
Argon gas-sealed device can greatly reduce amount and the time of applying argon gas.
The concrete scheme of the utility model is: a kind of argon gas-sealed device for steel pipe argon arc welding, it includes two groups of envelopes
Pipe device, every group of pipe sealing device include a skeleton, fix on skeleton and a circular seal plate is housed, the circular seal plate
Diameter is matched with the inner diameter of steel pipe to realize sealing, is connected between two groups of pipe sealing devices by iron chains, wherein one group of tube sealing
It is fitted with a tunger tube on device, traction rope is housed on another set pipe sealing device.
Skeleton described in the utility model includes two blocks of identical plectanes, and two blocks of plectanes are located at circular seal plate two sides,
Through-hole there are four being all provided on two blocks of plectanes and circular seal plate, through-hole, which is provided with steel wire, fixes two blocks of plectanes with circular seal plate
It is integrated.
Plectane described in the utility model is glued board.

The intermediate position fixation of iron chains described in the utility model is tied with one piece of red cloth.
Circular seal plate described in the utility model is foam-rubber cushion.
The length of iron chains described in the utility model is 40 ~ 60cm.
In utility model works specific steps are as follows: 1, select according to diameter of steel tube the circular seal of suitable size
Two groups of pipe sealing devices are filled in one end of a wherein steel pipe by plate；2, two steel pipes are docked, interface adhesive tape is close
Envelope；3, drawing traction rope makes pipe sealing device in in-pipe, observes to interface, stops drawing when seeing red cloth, at this time
Two groups of pipe sealing devices are located in two steel pipes, form a narrow confined space with adhesive tape；4, pass through tunger tube
To filling steel pipes with argon, argon arc welding operation is carried out, traction rope is pulled again after the completion of welding and pulls out two groups of pipe sealing devices.
The utility model has the advantage that 1, production is simple, is normal conventional material using material compared with prior art
Material, production can be completed in construction site；2, argon gas filled volume is greatly reduced, and can effectively stop argon gas loss, improves argon
