Abstract
The utility model discloses a device for argon-filling protection in welding. The device comprises a gas-filling tube and a sealed section; the two ends of the sealed section are sealed; the two sealed ends are connected together through a middle supporting piece; and the gas-filling tube is connected to one sealed end, and is communicated with the interior part of the sealed section. The device with reasonable structure design effectively solves the problem that the interior part of a welding seam is oxidized during the direct current welding of stainless steel tubes, and improves the welding quality of the stainless steel tubes. Compared with the flanged connection of the stainless steel tubes, the construction efficiency is improved, and the construction cost is greatly reduced. The device is especially suitable for marketing popularization.
Description
Technical field
The utility model relates to a kind of argon-filled protection welder, belongs to the gas shielded arc welding technical field, particularly a kind of argon-filled protection welder of building the stainless steel pipes welding.
Background technology
Along with improving constantly of social physical development level, stainless steel tube has obtained increasing application at building field, but since the particularity of its material, very easily oxidation of tube wall during welding, and welding quality can not get effective assurance; Inner-walls of duct protection when applying argon gas welds in pipe has been invented the argon-filled protection welder thus for a kind of effective welding method.
Utilization argon-filled protection welder carries out uninterrupted argon filling in stainless steel tube joint inside, and inside pipe wall is played a good protection, and has avoided the weld seam interior oxidation, the outside simultaneously manual argon arc welding that adopts.Be connected to compare with flange and saved cost greatly; Compare the oxidation that has alleviated weld seam greatly with the direct current weldering; Effectively guaranteed the welding quality of stainless steel pipes.
The utility model content
The purpose of this utility model is a kind of argon-filled protection welder that is used for the stainless steel pipes welding of design.
Content of the present utility model is: a kind of argon-filled protection welder, and this device comprises gas tube and seal section, and described seal section two ends are shutoff, and the two ends shutoff connects moulding by middle support member; Described gas tube is connected one of them shutoff, with the seal section internal communication.
Described shutoff comprises the hard clamping plate and the middle soft material sealing ring of both sides, and the size of described sealing ring is more bigger than the size of hard clamping plate; The material of hard clamping plate is generally selected steel plate, and the material of soft material sealing ring is generally selected rubber, certainly can resistant to elevated temperatures material for well.
Described support member is many harness cord screw rods, and two shutoff are passed at the two ends of screw rod respectively, and fixedlys connected with shutoff by nut.
Being shaped as of described shutoff is circular or square.
The beneficial effects of the utility model
The utility model project organization is reasonable, and the weld seam interior oxidation that causes when efficiently solving the welding of stainless steel pipes direct current has improved the stainless steel pipes welding quality; Be connected to compare with the stainless steel pipes flange and improved construction efficiency, reduced construction cost significantly.
The size of the sealing ring of this device is more bigger than the size of hard clamping plate, thereby avoids hard clamping plate and inner-walls of duct directly to contact the bad phenomenon of sealing of generation.
The different shutoff shape of this device can adapt to the welding of different bar section of stainless steel, and circular shutoff is used for welding pipe, and square shutoff is used for welding square tube, and perhaps without commonly used, but the scope of using at other field is not little at building field for square tube.

The specific embodiment
Embodiment one: referring to Fig. 1, Fig. 2, and Fig. 3, a kind of argon-filled protection welder among the figure, this device comprises gas tube 1 and seal section 4, and described seal section 4 two ends are shutoff 2 and 3, and two ends shutoff 2 is connected moulding with 3 by middle support member 5; Described gas tube 1 is connected one of them shutoff 2 or 3, is communicated with seal section inner 4.
Described shutoff 2 comprises the hard clamping plate 2-1 and the middle soft material sealing ring 2-2 of both sides, and the size of described sealing ring 2-2 is more bigger than the size of hard clamping plate 2-1; The material of hard clamping plate 2-1 is generally selected steel plate, and the material of soft material sealing ring 2-2 is generally selected rubber, certainly can resistant to elevated temperatures material for well.
Described shutoff 3 comprises the hard clamping plate 3-1 and the middle soft material sealing ring 3-2 of both sides, and the size of described sealing ring 3-2 is more bigger than the size of hard clamping plate 3-1; The material of hard clamping plate 3-1 is generally selected steel plate, and the material of soft material sealing ring 3-2 is generally selected rubber, certainly can resistant to elevated temperatures material for well.
Described support member 5 is many harness cord screw rods, and the two ends of screw rod are passed two shutoff 2 and 3 respectively, and fixedlys connected with 3 with shutoff 2 by nut 6.
Described shutoff 2 and 3 be shaped as circle.
Method of operating: referring to Fig. 3,10 is the argon-filled protection welder among the figure, 11 is soldered stainless steel pipes, when this stainless steel pipes welds counterpart, the argon-filled protection welder of shutoff size and pipeline section size coupling is placed stainless steel pipes inside, the shutoff at seal section two ends is fitted by sealing ring and inner-walls of duct sealing, and its seal section center is in two segment pipe joints; The gas tube of argon-filled protection welder is connected with the container of splendid attire argon gas; To the inner continual argon gas that charges into of stainless steel pipes, because the volume of pipeline joint seal section is limited, the air that is in the pipeline Butt Section is constantly squeezed out the pipeline Butt Section until emptying by argon gas, at this moment can weld smoothly by gas tube; In welding process, keep continuous argon filling, inner-walls of duct is protected, avoid its oxidation, finish until welding.
Embodiment two: accompanying drawing is not drawn, embodiment two and embodiment one are basic identical, something in common does not repeat, difference is, among the embodiment two shutoff be shaped as square because the structure of embodiment two and embodiment one are substantially always, just the shape of shutoff changes to some extent, therefore accompanying drawing omits, and the method for operating of this device and embodiment one are basic identical among the embodiment two, and different is the welding that this embodiment is applicable to the stainless steel square tube.
