Abstract

The utility model discloses a welding platform without back chipping for a welded H-shaped steel web plate and a wing plate, and relates to the technical field of welding construction, in particular to the field of construction of T-shaped welds. The welding platform solves the technical problem that when the welded H-shaped steel is manufactured, the back chipping is required in the welding process of the web plate and the wing plate, and the welding deformation is large. A welding joint of the web plate is designed into a K-shaped groove, the angle of the groove is 55 degrees, the included angle between a lateral object carrying platform and a bottom plate is the angle beta of the welding platform, and the angle beta is 55 degrees to 60 degrees. The welding platform is suitable for manufacturing and welding the welded H-shaped steel of the web plate with a thickness of 16 to 50mm, and solves the technical problem that the back chipping is required and the larger angle deformation is formed between the wing plate and the web plate when the welded H-shaped steel web plate and the wing plate are welded. The welding platform has the advantages that the convenience and the easy operation are realized, the manufacture cost is reduced, and easy popularization is realized.

Description

Welded H section steel web and wing plate are exempted from the back chipping jig
Technical field
The utility model relates to the shower of welding procedure technology, and particularly welded H section steel web and wing plate are exempted from the back chipping jig.
Background technology
According to structure steel fabrication welding GB50205-2001 standard, make welded H section steel T connector Weld quality level and be I and II, require full penetration.When making welding quality grade was the H shaped steel of I and II, traditional handicraft generally adopted single V-butt welding at present, and bevel angle is 45 ~ 50 degree, and the angle of jig is 45 degree, and the V-shaped weld reverse side is taked the welding procedure of carbon arc air gouging back chipping.The shortcoming of this welding procedure is: 1, groove face is substantially parallel with submerged-arc welding wire, and the separated time deviation is larger in welding wire and the bevel angle, causes the root of weld can not through welding, thus the welding point reverse side need the carbon arc air gouging back chipping after welding just can guarantee through welding.2, the both sides groove behind the back chipping is different, it is inconsistent that metal is filled in the web both sides, cause producing larger angular deformation after the welding of wing plate and web, this angular deformation can't adopt the shaped steel inspection machine to proofread and correct, must adopt flame correction, the correction work amount is large, residual larger internal stress after proofreading and correct, and the oxygen-acetylene consumption is large simultaneously.3, because single V-butt degree of depth is large, the filling metal is many, and material and manpower consumption are large.
Summary of the invention
The purpose of this utility model is to provide a kind of welded H section steel web and wing plate to exempt from the back chipping jig, solves when welded H section steel is made, and needs the large technical problem of back chipping and welding deformation in web and the wing plate welding.
The utility model solves the problems of the technologies described above and is achieved in that 1, changes the web slope type into K shape groove, bevel angle is designed to 55 degree, the angle of jig is adjusted into 55 ~ 60 degree by 45 original degree, above-mentioned angular deviation should be greater than 1 degree, the angle of groove face and submerged-arc welding wire is actual at this moment is 20 ~ 25 degree, in this angular range, need not in the situation of back chipping, Lincoln weld can guarantee the through welding of web and wing plate welding point.2, because welding point both sides bevel angle is identical, full symmetric, so weld seam both sides filling metal is consistent, can not produce angular deformation between wing plate and web.3, the scope of this new technology covering welded H section steel is wider, and the thickness of web all can adopt in 16 ~ 50 millimeters.
Jig of the present utility model comprises base plate, bearing diagonal plate, vertical gripper shoe, main article carrying platform, side article carrying platform.Base plate, vertically gripper shoe and the main article carrying platform three triangle that meets at right angles is fixedly connected with layout, and wherein floor level is placed, and vertical gripper shoe arranges that vertically main article carrying platform is the hypotenuse of right angled triangle.The bearing diagonal plate is arranged between the junction and main article carrying platform of base plate and vertical gripper shoe, and connected mode makes main article carrying platform more firm for being fixedly connected with.One side of side article carrying platform is fixedly connected with the junction of base plate and main article carrying platform, and the side article carrying platform is arranged vertically with respect to main article carrying platform, and the angle of side article carrying platform and base plate is the jig angle beta, and β is 55 ~ 60 degree.
Concrete using method of the present utility model is: the first step, and processing web groove adopts the automatic cutter of oxy-acetylene that the web groove is processed into both sides and is symmetrical K shape groove, and bevel angle α is 55 degree; Second step, assembling H shaped steel is placed on the H shaped steel that assembles on the jig, and the jig angle beta is 55 ~ 60 degree; The 3rd step, to adjust the welding technology of automatic submerged-arc welding parameter and weld, submerged-arc welding wire is vertical state, the angle of groove face and submerged-arc welding wire is actual at this moment is 20 ~ 25 degree, in time carry out standing up of H shaped steel, be symmetrically welded in the weld seam both sides, until finish welding.
The beneficial effects of the utility model are: the utility model needs back root cleaning and produce the technical problem of larger angular deformation between wing plate and web when having solved welded H section steel web and wing plate welding, has compared following advantage and improvement with traditional handicraft.
The first, because the change of grooves of welding joints pattern and jig angle in this angular range, need not in the situation of back chipping, Lincoln weld can guarantee the through welding of web and wing plate welding point.
The second, because welding point both sides bevel angle is identical, full symmetric, so weld seam both sides filling metal is consistent, can not produce angular deformation between wing plate and web.
The 3rd, slope type changes K shape groove into by single V-butt, fills amount of metal and reduces.Save material, reduced manpower consumption, reduced cost of manufacture, shortened the process-cycle.
