Abstract
The utility model discloses an assist and weld structure that is used for cut deal tubular product spare submerged arc welding has welding substrate and bed hedgehopping portion, and the surface of welding substrate has plane portion and concave part, on the cut deal tubular product spare back was located to bed hedgehopping portion pad, the corresponding main weld department at the cut deal tubular product spare back was located to the welding substrate, and its main weld outlying plane area of cut deal tubular product spare is hugged closely by its midplane portion, and the concave part is just to the main weld setting. The structure is welded in this novel assistance can make submerged arc welding production efficiency greatly improved, and welding deformation easily controls, and the molten bath transition is fuller, and weld quality easily guarantees, weld forming is more pleasing to the eye, and construction cost reduces more.
Description
Technical field
The utility model relates to submerged arc welding technical field, specifically refers to a kind of auxiliary welding structure for the submerged-arc welding of cut deal tubing member.
Background technology
At present, to medium-thick plate main weld, the docking of pipe fitting main weld, submerged-arc welding (or carbon dioxide arc welding) bottoming, filling, capping, reverse side is needed to carry out carbon arc air gouging back chipping again by the welding method of routine, electronic pneumatic shovel shovel slag, electric angle grinder polishing back chipping welding bead, then carry out submerged-arc welding (or carbon dioxide arc welding) bottoming, filling, capping.But this conventional soldering method has, and welding work pieces is out of shape greatly, welding efficiency is low, labour intensity is large, production efficiency is low, weldquality not easily ensures, cost drops into high series of problems, if employing Plasma Welding, although be out of shape little, efficiency is high, but welding equipment investment is huge, and general enterprises is difficult to the investment expense bearing apparatus expensive.
Utility model content
The purpose of this utility model is to provide a kind of auxiliary welding structure for the submerged-arc welding of cut deal tubing member, it can make, and welding production efficiency is greatly improved, welding deformation is easy to control, molten bath transition is fuller, appearance of weld is more attractive in appearance, and weldquality is easy to guarantee, construction cost is cheaper.
In order to reach above-mentioned purpose, solution of the present utility model is:
For an auxiliary welding structure for cut deal tubing member submerged-arc welding, have welding substrate and padded portion, the surface of welding substrate has planar portions and recess; Padded portion pad is located on the cut deal tubing member back side, and welding substrate is located at the corresponding main weld place at the cut deal tubing member back side, and wherein planar portions is close to the plane area of its main weld periphery of cut deal tubing member, and recess is just arranged main weld.
The opening's edge radial dimension of described recess is greater than the gap of main weld.
Described padded portion has two groups, left and right, is arranged at two side positions of welding substrate.
The height in described padded portion is equal with the height of welding substrate.
Described welding substrate adopts dedicated ceramic flexible welding substrate.
After adopting such scheme, this Novel auxiliary welding structure is used for the auxiliary weldering effect of cut deal tubing member submerged-arc welding, back side pad inside the groove of the main weld of cut deal tubing member pastes welding substrate (being preferably dedicated ceramic flexible welding substrate), and cut deal tubing member adopts padded portion steadily padded.Welding substrate has planar portions and recess; the plane area of planar portions and cut deal tubing member fits tightly; recess is used for setting off the weld metal (recess can also lead to nitrogen more effectively to protect weld metal) at the back side; make it not oxidized; thus improve inherent quality and the presentation quality of weld seam; guarantee the shaping of fillet in normal shear and quality, also effectively improve welding condition.Thus make that welding production efficiency is greatly improved, welding deformation is easy to control, molten bath transition is fuller, and appearance of weld is more attractive in appearance, and weldquality is easy to ensure, construction cost is cheaper.
Accompanying drawing explanation
Fig. 1 is the application schematic diagram of the auxiliary welding structure of this Novel cut deal tubing member submerged-arc welding.
Label declaration
Welding substrate 1 planar portions 11
The padded portion 2 of recess 12
Cut deal tubing member 3 main weld 31.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of auxiliary welding structure for the submerged-arc welding of cut deal tubing member, as shown in Figure 1, has welding substrate 1 and padded portion 2.The surface of welding substrate 1 has planar portions 11 and recess 12.
Padded portion 2 pad is located on the back side of cut deal tubing member 3; Particularly, padded portion 2 has two groups, left and right, is located at the both sides place of its main weld 31 of cut deal tubing member 3 respectively.Welding substrate 2 is located at corresponding main weld 31 place at cut deal tubing member 3 back side, and wherein planar portions 11 is close to the plane area of its main weld 21 periphery of cut deal tubing member 3, then recess 12 is just arranged main weld 31.Preferably, the opening's edge radial dimension of recess 12 is greater than the gap of main weld 31, and namely whole main weld 31 is in recess 12 completely.Recess 12 is curved groove structure preferably.
Preferably, the height in padded portion 2 is equal with the height of welding substrate 1, in this welding substrate 1 and padded portion 2 together gentle support cut deal tubing member 3, and welding substrate 1 also can be made bonded to each otherly tightr with the plane area of cut deal tubing member 3.Padded portion 2 is preferably steel sleeve, for the reversible deformation prevention and control of cut deal tubing member 3.
Described welding substrate 1 preferably adopts dedicated ceramic flexible welding substrate, and it has the characteristic of high temperature resistant (550 DEG C).
In the application of this Novel auxiliary welding structure, back side pad inside the groove of medium-thick plate or pipe fitting main weld 31 pastes welding substrate 1, and lead to nitrogen at recess 12 place, welding gun head is fixed on the extension arm of Lincoln weld, carries out Lincoln weld welding (at the bottom of bottoming, filling weldering, cosmetic welding) to groove side.Adopt dedicated ceramic flexible welding substrate; there is the characteristic of high temperature resistant (550 DEG C); can be used for setting off the weld metal at the back side; the back side leads to nitrogen; more effectively can protect weld metal; make it not oxidized; thus improve the presentation quality of main weld and ensure the inherent quality of weld seam; and cool with nitrogen butt welded seam; main weld is not yielding, and welding gun is bundled on automatic submerged-arc welding machine extension arm, not only makes welding more stable; guarantee shaping and the inherent quality of fillet in normal shear, also effectively improve welding deformation.This Novel auxiliary welding structure can make production efficiency be greatly improved, and welding deformation is easy to control, and molten bath transition is fuller, and weldquality is easy to guarantee, appearance of weld is more attractive in appearance, and construction cost reduces more.
The foregoing is only the preferred embodiment that this is novel, all equalizations done with this novel right change and modify, and all should belong to the scope of this novel claim.
