Description
Technical field
The utility model is related to machinery industry welding processing technical fields, and in particular to Hastelloy and Nickel-based Alloy Welding
Back protection device.
Background technology
Hastelloy and nickel-base alloy poor fluidity, solid liquid phase temperature range is small, and thermal conductivity is low, and liquid state molten pool is soluble
H2, O2, CO2Equal gases, when solidification, the solubility of these gases is significantly reduced, to form hydrogen blistering and vapor gas
Hole seriously affects the quality of welding point, therefore when Hastelloy and Nickel-based Alloy Welding, and weld seam needs fully to protect in addition to front
Shield is outer, and back is also required to adequately protect, and the back protection device of existing Hastelloy and Nickel-based Alloy Welding is generally one
A upper opening of protective cover, one snorkel of placement is passed through protective gas in protective cover, and protective device cannot be fixed directly
At the back side of welding material, other people or device is needed to be fixed, meanwhile, protective cover upper end shape is fixed, cannot basis
Material surface is adjusted, and the surface stickiness of protective cover and material to be welded is poor, is unfavorable for backside gas protection.
Invention content
Technical problem to be solved in the utility model is：Hastelloy and Nickel-based Alloy Welding back-protective dress are provided
It sets, can effectively solve the problems, such as due to needing individually fixed when existing apparatus uses and cannot being bonded with material surface.
The purpose of this utility model is realized by following technical measures：
Hastelloy and Nickel-based Alloy Welding back protection device, including cover body and the snorkel in cover body is stretched into, it is described
Cover body includes multiple chain links formed by bottom plate and two side plates, and the side plate lower end is interconnected by axis pin, described in two
Side plate is oppositely arranged on the bottom plate, and the both ends of the cover body are equipped with baffle, and the upper end of the side plate and the baffle is all set
There are magnet piece, the snorkel to pass through the baffle of side and extend to the baffle of the other side.
Further, the homonymy of two opposite side plates is designed with screening glass, opposite two screening glass it is outer
Diameter is identical as the opposite internal diameter of two side plates.
Further, the screening glass is one kind in semicircle, sector or triangle.
Further, it is uniformly provided with airflow hole on the snorkel.
Further, the aperture of the airflow hole is φ 2-8mm.
After using said program, the utility model has the beneficial effects that：
The cover body of the utility model Hastelloy and Nickel-based Alloy Welding back protection device includes multiple by bottom plate and two
The chain link that a side plate is formed, side plate lower end are interconnected by axis pin, can be according to the shape adjustment cover body on welding material surface
Shape, so that cover body is bonded with material surface；The upper end of side plate and baffle is designed with magnet piece, protection can be made to fill by magnet piece
It sets and is fixed on welding material automatically, be conducive to the gas shield to welding material surface.
Since the homonymy of side plate is designed with screening glass, the internal diameter phase of the outer diameter of two screening glass and two opposite side plates
Together, when adjusting mask body shape according to welding material, protection can be formed between two adjacent side plates, reduce protective gas
Spilling.
It is uniformly provided with airflow hole on snorkel, is uniformly distributed in cover body conducive to protective gas.
In conclusion the utility model Hastelloy and Nickel-based Alloy Welding back protection device can be according to welding materials
Surface adjusts the shape of cover body, so that cover body surface is bonded the close gas shield being conducive to welding material surface with material, simultaneously
It can be fixed on the surface of material automatically, it is easy to use.

Specific implementation mode
To make technological means, creation characteristic, the purpose reached and effect of the utility model be easy to understand, tie
The drawings and the specific embodiments are closed, the utility model is expanded on further.
As illustrated in figs. 1 and 2, the utility model Hastelloy and Nickel-based Alloy Welding back protection device, including cover body 1
With the snorkel 2 stretched into cover body, cover body 1 is made of multiple chain links 3 connected by axis pin 4, and chain link 3 is by bottom plate 31 and two
Side plate 32 forms, and on bottom plate 31, adjacent two 32 lower ends of side plate are connected the opposite setting of two side plates 32 by axis pin 4,
The homonymy of two opposite side plates 32 is designed with screening glass 33, the outer diameter D of opposite two screening glass 33 and two opposite sides
The internal diameter d of plate 32 is identical, and screening glass 33 is one kind in semicircle, sector or triangle, when two adjacent chain links 3 rotate
When, screening glass 33 can form protection between chain link 3, prevent gas from being overflowed between two side plates；The both ends of cover body 1 are equipped with gear
The upper end of plate 5, side plate 33 and baffle 5 is designed with magnet piece 6, by the suction-operated of magnet piece 6, device is made to be fixed on weldering automatically
Connect material surface；Snorkel 2 passes through the baffle of side and extends to the baffle of the other side, and airflow hole is uniformly provided on snorkel 2
21, the aperture of airflow hole is φ 2-8mm, is uniformly distributed in cover body conducive to protective gas.
The utility model Hastelloy and Nickel-based Alloy Welding back protection device can be adjusted according to the surface of welding material
The shape of cover body makes cover body surface be bonded the close gas shield being conducive to welding material surface with material, while can consolidate automatically
It is scheduled on the surface of material, it is easy to use.
Above-described embodiment is the preferred embodiment of the utility model, but the implementation of the utility model is not by above-described embodiment
