Abstract
The utility model discloses a welding device for circumferential weld gas shielded arc welding, which comprises a gas shielded arc welding torch, a hollow annular ring, a rotary jig frame and a fixed bracket. An air inlet port is formed on the outer ring of the annular ring and connected with a combustion gas source; a plurality of air outlet ports are radially formed on the inner ring of the hollow annular ring at intervals; the hollow annular ring is positioned on the rotary jig frame; the fixed bracket is vertically arranged on the rotary jig frame; and the gas shielded arc welding torch is arranged at the top end of the fixed bracket. The welding device can carry out the welding operation to heavy plate circumferential welds, ensure the weld joint quality, reduce the work intensity and improve the welding efficiency.
Description
Technical field
The utility model relates to the welder that a kind of circular weld gas is protected weldering.
Background technology
The welded pipe wall thickness is wanted elimination welding deformation as much as possible and weld defect during greater than the pipe steel construction of 30mm, so technological requirement is that circular weld is carried out preheating, and also will guarantee interlayer temperature in welding process.But special-purpose at present circular weld welding equipment self is heavier, carrying is very inconvenient, for on-the-spot weld job has brought difficulty, and be generally the point-like heating during its preheating, the point-like heating can not be satisfied the preheating requirement of slab circular weld, the hardenability of welding is increased, cause cold crack easily.The welding of slab circular weld simultaneously if use conventional by manually-operated gas shielded arc welding, then may be because the welding process cut deal is heated the inhomogeneous welding deformation that causes, and welding labour intensity is big, efficient is low.
Summary of the invention
Technical problem to be solved in the utility model provides the welder that a kind of circular weld gas is protected weldering, utilizes this device can conveniently carry out the weld job of slab circular weld, has guaranteed weldquality, reduces labour intensity, has improved welding efficiency.
For solving the problems of the technologies described above, the welder that the utility model circular weld gas is protected weldering comprises gas guarantor weldering welding gun, hollow ring circle, rotation moulding bed and fixed support, described hollow ring circle outer ring is provided with air admission hole and connects the burning source of the gas, described hollow ring circle inner ring radially is interval with some ventholes, described hollow ring circle is positioned on the described rotation moulding bed, described fixed support is vertical on the described rotation moulding bed, and described gas is protected the weldering welding gun and is located at described fixed support top.
For improving the combustion efficiency of the some venthole emergent gas of hollow ring circle inner ring, some venthole spacings of above-mentioned hollow ring circle inner ring can be made as the 60-90 millimeter.
Because the utility model circular weld gas is protected the welder of weldering and has been adopted technique scheme, promptly on the rotation moulding bed, a hollow ring circle is set, hollow ring circle outer ring has air admission hole, inner ring and has some ventholes at interval, fixed support is vertical on the rotation moulding bed, and gas is protected the weldering welding gun and is located at the fixed support top; This device can conveniently carry out the weld job of slab circular weld, has guaranteed weldquality, reduces labour intensity, has improved welding efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation that the utility model circular weld gas is protected the weldering welder,
Fig. 2 is the side view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the welder that the utility model circular weld gas is protected weldering comprises gas guarantor weldering welding gun 4, hollow ring circle 1, rotation moulding bed 2 and fixed support 3, described hollow ring circle 1 outer ring is provided with air admission hole 11 and connects burning source of the gas 13, described hollow ring circle 1 inner ring radially is interval with some ventholes 12, described hollow ring circle 1 is positioned on the described rotation moulding bed 2, described fixed support 3 is vertical on the described rotation moulding bed 2, and described gas is protected weldering welding gun 4 and is located at described fixed support 3 tops.
For improving the combustion efficiency of the some venthole emergent gas of hollow ring circle inner ring, some ventholes 12 spacings of above-mentioned hollow ring circle 1 inner ring can be made as the 60-90 millimeter.
The welder that the utility model circular weld gas is protected weldering is provided with a hollow ring circle 1 on the rotation moulding bed, hollow ring circle 1 outer ring has air admission hole 11, inner ring and has some ventholes 12 at interval, fixed support 3 is vertical on the rotation moulding bed 2, and gas is protected weldering welding gun 4 and is located at fixed support 3 tops; During the work of this device, need the steel pipe 5 of welding to be arranged on the roller 21 that rotates moulding bed 2 and weld seam 51 butt joints with two sections, wherein one section steel pipe penetrates in the hollow ring circle 1, hollow ring circle 1 is positioned at weld seam 51 1 sides, hollow ring circle 1 cavity is connected burning source of the gas 13 and is lighted inner ring venthole 12, the inner ring flame butt welded seam 51 of hollow ring circle 1 heats at this moment, after adjusting gas simultaneously and protecting weldering parameter and weld seam 51 heating and put in place, start rotation moulding bed 2 two sections steel pipes are rotated, the welding gun 4 that is arranged at fixed support 3 tops can be implemented the weld job of circular weld.
This device adopts the hollow ring circle as the pre-hot tool of weld seam, can satisfy the preheating simultaneously of whole piece weld seam, and guarantees that the interlayer temperature of weld seam in the welding process meets the requirements.This hollow ring circle is simply light, is easy to carry and adjusts.Steel pipe is arranged on the rotation moulding bed and rotates the welding realized circular weld, and welding parameter is not easy to be interfered in the welding process, plays a good guarantee effect for the quality of weld seam.By the rotation of steel pipe, realize the near symmetrical welding of circular weld in the while welding process, digested weld seam so to a certain extent and shunk the pipe deformation that causes, can not cause the side sway of steel pipe after welding finishes, guaranteed welding quality.
