Abstract
Disclosed is a track type outside longitudinal joint submerge-arc automatic welding device, comprising a welder and a strip shape support, a soldering wire feed device is disposed in the welder, the strip shape support consists of two steel channel members in parallel and spaced arrangement, both the welder and the soldering wire feed device are disposed above the strip shape support and gaps are disposed between the welder and the soldering wire feed device and the strip shape support, and an inflatable canvas hose is disposed between the two steel channel members. A pressure container to be welded is positioned on the strip shape support, an inside longitudinal joint on the circumferential wall of the pressure container is positioned between the two steel channel members in parallel and spaced arrangement, a welding flux is filled between the upper part of the inflatable canvas hose and the circumferential outer wall of the pressure container, after the canvas hose is inflated, the welding flux is coated tightly on the circumferential outer wall of the pressure container. The utility model realizes submerge-arc automatic welding of the inside longitudinal joint, has no electric arc ray radiation, spatter and smoke gas, protects the health of welders, has high weld quality, fast welding speed and deep weld penetration, and reduces the rate of dependency of operating skills of welders.
Description
Technical field:
The utility model relates to metal welding techniques, relates in particular to interior longitudinal joint Lincoln weld technology on the pressure vessel, the outer longitudinal joint Lincoln weld device of particularly a kind of rail mounted.
Background technology:
In the prior art, be parallel to its axial interior longitudinal joint on the pressure vessel circumferential wall and adopt manual arc to weld.Speed of welding is slow, fusion penetration is shallow, manual electric arc welding is operated by welder's hand torch, welded a root bead bar, will change another root bead bar and weld, and will weld multilayer or multiple tracks under the thicker situation of steel plate thickness, long-time people welds in container, as easy as rolling off a logly feel tired, particularly in hot season, the National People's Congress measures sweat, can suffer heatstroke; The electrode coating of manual electric arc welding is acid compound or is made up of alkali compounds, after high temperature melting is decomposed, discharges gas and flue dust, the welder easy the pneumoconiosis occupational disease, strong electric arc ultraviolet can be stabbed eyes; Waste morely, welded a root bead bar, one section discard electrode is just arranged, a large amount of discard electrodes forms waste; Postwelding has a large amount of splashing and slag.
Summary of the invention:
The purpose of this utility model is to provide a kind of rail mounted outer longitudinal joint Lincoln weld device, and the outer longitudinal joint Lincoln weld device of described this rail mounted will solve that longitudinal joint speed is slow in the manual arc welding pressure vessel in the prior art, fusion penetration is shallow, labour intensity is big, the pneumoconiosis that is easy to get, the welding rod waste is many, generation is splashed in a large number and the technical problem of slag.
The outer longitudinal joint Lincoln weld device of this rail mounted of the present utility model is propped up by a welding machine and a stripe shape and is configured to, be provided with the welding wire feeder in the described welding machine, wherein, described stripe shape support is made of the channel-section steel member of two parallel interval settings, described welding machine and welding wire feeder thereof all be arranged on the stripe shape support the top and and the stripe shape support between be provided with the gap, be provided with an inflatable sail pipe between described two channel-section steel members.
Further, described two channel-section steel members notch direction in its section is opposite.
Further, an end of described inflatable sail pipe is connected with a compressed air source.
Further, the other end of described inflatable sail pipe sealing.
Concrete, welding machine described in the utility model, welding wire feeder, channel-section steel member and canvas duct all adopt known schemes of the prior art, about welding machine, welding wire feeder, channel-section steel member and canvas duct known solution, those skilled in the art all understands, does not repeat them here.
Operation principle of the present utility model is: pressure vessel to be welded is placed on the stripe shape support, and the interior longitudinal joint that makes the pressure vessel circumferential wall is between the channel-section steel member that two parallel interval are provided with, between two channel-section steel members, filling flux between the top of inflatable sail pipe and the outer circumferential walls of pressure vessel, behind the inflatable sail pipe inflation, the outer circumferential walls of solder flux being close to pressure vessel, welding wire feeder in the welding machine is aimed at the interior longitudinal joint of pressure vessel circumferential wall, and along interior longitudinal joint accumulation solder flux, start welding machine, get final product the interior longitudinal joint of welding pressure container circumferential wall, and owing to be glued with solder flux on the outer circumferential walls of pressure vessel, weld seam can be by burn-through.
The utility model compared with the prior art, its effect is actively and significantly.The welder of longitudinal joint in the utility model utilizes welding machine and stripe shape to prop up to be configured on the pressure vessel; the Lincoln weld of longitudinal joint in can realizing; welding machine is sent welding wire continuously to; solder flux and slag thereof are protected around covering electric arc; there is not the arclight radiation; also do not splash and flue dust; protected welder's health, the weldquality height, the chemical composition of weld seam and mechanical property are good; appearance of weld is attractive in appearance; speed of welding is fast, and weld penetration is dark, the following steel plate of general 14mm; but square groove has reduced the degree of dependence of welder's operative skill.
Description of drawings:
Fig. 1 is the structural representation of the outer longitudinal joint Lincoln weld device of rail mounted of the present utility model.
The specific embodiment:
As shown in Figure 1, the outer longitudinal joint Lincoln weld device of rail mounted of the present utility model, prop up by a welding machine (not shown) and a stripe shape and to be configured to, be provided with welding wire feeder 4 in the described welding machine, wherein, described stripe shape support is made of the channel-section steel member 5 of two parallel interval settings, described welding machine and welding wire feeder 4 thereof all be arranged on the stripe shape support the top and and the stripe shape support between be provided with the gap, be provided with an inflatable sail pipe 3 between described two channel-section steel members 5.
Further, described two channel-section steel members 5 notch direction in its section is opposite.
Further, an end of described inflatable sail pipe 3 is connected with a compressed air source (not shown).
Further, the other end of described inflatable sail pipe 3 sealing.
Concrete, the welding machine described in the utility model, welding wire feeder 4, channel-section steel member 5 and canvas duct all adopt known schemes of the prior art.
The course of work of present embodiment is: pressure vessel to be welded 1 is placed on the stripe shape support, and the interior longitudinal joint that makes pressure vessel 1 circumferential wall is between the channel-section steel member 5 that two parallel interval are provided with, between two channel-section steel members 5, filling flux 2 between the outer circumferential walls of the top of inflatable sail pipe 3 and pressure vessel 1, behind inflatable sail pipe 3 inflations, the outer circumferential walls of solder flux 2 being close to pressure vessel 1, welding wire feeder in the welding machine 4 is aimed at the interior longitudinal joint of pressure vessel 1 circumferential wall, and along interior longitudinal joint accumulation solder flux, start welding machine, get final product the interior longitudinal joint of welding pressure container 1 circumferential wall, and owing to be glued with solder flux 2 on the outer circumferential walls of pressure vessel 1, weld seam can be by burn-through.
