The utility model has the advantages of simple and reasonable structure, configuration pressure regulating flowmeter, gas flow and pressure are all adjustable, supply gas in advance through the solenoid valve, and the hysteresis is died, the effectively reasonable argon gas that utilizes, the back shaping of butt welded seam and prevent that the oxidation from having played fine control.
Description
Technical field
The utility model relates to Plasma Welding technical field, is specifically related to a kind of back of the body gas shielded device being applied to Plasma Welding.
Background technology
When Plasma Welding technology is applied to the docking of the thin plate such as stainless steel and titanium plate, when requiring weld seam complete penetraction and fusion in welding and can only weld from the one side of joint, except adopting the solder technology of one side welding with back formation, also should increase red copper welding backing at the back side of weld seam.Adopt copper liner at joint base layer support welding pool, be applicable to straight butt weld.
But there is following shortcoming in conventional art:
Traditional back of the body gas shielded device protection gas used is argon gas, and back of the body air drain is square, too smallly affects back side shape, the excessive waste causing gas.Protect the size of the Flow-rate adjustment of gas and forming tank all not too reasonable.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides a kind of back of the body gas shielded device being applied to Plasma Welding.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
Be applied to a back of the body gas shielded device for Plasma Welding, comprise the liner being arranged on back of weld; Described liner is in series by copper cushion block; Described cushion block is provided with open recess; The pipeline for injecting cooling water is provided with in described cushion block; Protection gas passage is also provided with in described liner.
Can lead to cooling water in cushion block, butt welded seam back provides pressure cooling forming, and water-cooled copper backing plate can absorb rapidly the heat energy around weld seam simultaneously, reduces the heat affected area of weld seam, effectively prevents the thermal deformation of workpiece.
Further technical scheme is that open recess comprises the upper groove that the is arranged on described cushion block top low groove relative with described upper groove position with being arranged on described cushion block bottom, passes through open communication between described upper groove and described low groove.Such groove can not only hold back-protective gas, also for plasma jet provides a space passed.
Further technical scheme is liner is that red copper material is made.Utilize the copper liner of open recess in order to support molten bath, when adopting the welding of plasma orifice method, molten bath is supported by surface tension, and the molten iron in molten bath does not contact with gasket groove, and the thermal conductivity of copper is higher, contributes to preventing weld metal and liner from fusing.
Further technical scheme is that protection gas expanding channels has appendix, described appendix is provided with pressure regulation flowmeter.Make gas flow and pressure all adjustable.
Further technical scheme is that appendix is provided with magnetic valve.By magnetic valve preflow, delayedly to die, effective and reasonable utilizes argon gas.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple and reasonable, configuration pressure regulation flowmeter, gas flow and pressure are all adjustable, by magnetic valve preflow, delayedly die, effective and reasonable utilizes argon gas, and bead formed on back and the anti-oxidation of butt welded seam serve good control.
Accompanying drawing explanation
