Abstract

The invention relates to a welding device for the flanging of a pipeline connecting piece, which is characterized by comprising a welding base, an annular welding pressing plate, a pressing plate fill block and a gas pipe, wherein an annular flange is arranged in the middle of the welding base; the outside of the annular flange is provided with an annular groove; the annular welding pressing plate is installed and connected on the welding base; a gas channel is arranged in the welding base; one end of the gas channel is communicated with the gas pipe; and the other end of the gas channel is communicated with the annular groove. The welding device has the advantages of the use amount of welding shield gas is reduced by 60-80%, the welding efficiency is high, the subsequent shaping process is omitted and the production efficiency is improved.

Description

A kind of welder of flange of conduit coupling
One, technical field
The present invention relates to a kind of welder, relate in particular to a kind of welder of flange of conduit coupling.
Two, background technology
Weldering system flange (welding neck collar) is usually used in medium temperature and pressure is not high and in the pressure pipeline that corrosive medium is stronger.When corrosive medium was strong, the part of flange contact medium (flange) be materials such as corrosion resistant high-grade material such as stainless steel, and is outside then utilize the flange ring of low grade material such as carbon steel material to clamp it to seal with realization; So just can reduce the cost of whole piece pipeline.Weldering system flange (welding neck collar) because; Weldering system flange all is special materials such as stainless steel or copper alloy, nickel-base alloy, Hastelloy; When the bottoming welding, need the applying argon gas protection, special material such as Hastelloy more needs high-purity argon gas protection, and this has increased welding cost undoubtedly.In addition, overlap edge is easy to produce welding deformation owing to receive the influence of the welding stress of angle welding, is easy to cause the sealing surface of flange to process.
Three, summary of the invention
To above-mentioned shortcoming, the object of the present invention is to provide the welder of flange that a kind ofly can reduce the argon gas consumption, be not easy to produce the conduit coupling of welding deformation.
Technology contents of the present invention is that a kind of welder of flange of conduit coupling is characterized by it and comprises welding base, annular solder pressing plate, pressing plate cushion block and appendix; There is annular lip centre at the welding base, is provided with an annular groove in the annular lip outside; The annular solder pressing plate is installed and is connected on the welding base, in the welding base, is provided with gas distribution channel, and an end of gas distribution channel is communicated with appendix, and the other end of gas distribution channel communicates with annular groove.
What the present invention was compared with prior art had is a little:
(1), the welding protection gas usage reduces 60-80% and welding efficiency height.
(2), reduced follow-up trimming, improved production efficiency.
Four, description of drawings
Fig. 1 is a structural representation of the present invention.
Five, specific embodiment
As shown in Figure 1, a kind of welder of flange of conduit coupling is characterized by it and comprises welding base 1, annular solder pressing plate 2, pressing plate cushion block 3 and appendix 4; There is annular lip 1.1 centre at welding base 1, is provided with an annular groove 1.2 in annular lip 1.1 outsides; Annular solder pressing plate 2 is installed and is connected on the welding base 1, in welding base 1, is provided with gas distribution channel 1.3, and an end of gas distribution channel 1.3 is communicated with appendix 4, and the other end of gas distribution channel 1.3 communicates with annular groove 1.2.
Operation principle of the present invention is: the annular lip 1.1 of welding base 1 centre is inserted in the adapter 5 that will weld flange, and the flange 6 that will weld is placed on the welding base 1 and is enclosed within takes over 5 outsides; Annular solder pressing plate 2 and on press-fiting on flange 6 limits at flange 6 underlay pressing plate cushion blocks 3, the welded gaps 7 of adjustment weldering system flange overlap edge and adapter, to around between welding gap 7 even, annular groove 1.2 aligning welded gaps 7; Tight a bolt and 8 make annular solder pressing plate 2 compress flange 6; Spot welding weldering system flange 6 and adapter 5, appendix 4 input protection gases (argon gas) make protective gas spray into welded gaps 7 through gas distribution channel 1.3 by annular groove 1.2 simultaneously, and butt tube 5 carries out welding protection with the backing welding of flange 6.

Claims (1)
