Description

Full penetration welding H-shaped steel for radial difference arc groove weld joint

Technical Field

The utility model relates to a welding shaped steel, in particular to full penetration welding H shaped steel of footpath poor arc chute welding seam.

Background

The traditional welding type H-shaped steel is manufactured by welding two flange plates at two ends of a web plate by using a welding technology, welding feet are only formed at two sides of the web plate by the technology, the vertical contact surface of the web plate and the flange plates is subjected to empty welding, and the structural strength is not ideal (as shown in figure 1). In order to make up for the defect, a welding seam processing step is added in the existing welding process, and two sides of a web plate are provided with symmetrical or asymmetrical slopes of 45-55 degrees, so that the filling amount of the welding flux and the welding area are increased (as shown in figure 2). However, the blank welding part of the vertical contact surface between the web and the flange plate still exists in the mode, because if the two slope surfaces are butted, the usage amount of welding flux is large, the build-up welding can be formed, and if the slope angle is reduced on the basis, the welding head is not easy to wedge, so compared with the traditional process product, the existing web processing technology increases the welding strength of the product, but still cannot realize full-penetration welding without dead angles.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is how to overcome prior art's above-mentioned defect, provide one kind can not have the dead angle to fill and complete penetration weld even, and save the poor arc groove welding seam full penetration welding H shaped steel in footpath of solder relatively.

For solving above-mentioned technical problem, this poor arc chute welding seam of footpath melts completely and welds H shaped steel include web, perpendicular submerged arc welding at the flange board at web both ends, be used for the leg of welded fastening web and flange board, open at both ends on the web has the arc groove, open flange board central part has the arc slot, the radius of arc groove is less than the radius of arc slot, the radian of arc groove equals the radian of arc slot, the leg outside extends to web and flange board lateral wall, and the inside penetration of leg fills the welding seam clearance between arc groove and the arc slot. By the design, almost continuous welding seam gaps (except the contact points of the arc grooves and the arc grooves) are formed at the splicing positions of the web plates and the flange plates, and the welding flux is melted and penetrated into the welding seam gaps by a submerged arc welding method, so that blind-corner-free ring welding is formed. Compared with the existing web double-side slope technology, the arc-shaped groove and the arc-shaped groove are structurally designed, so that the welding dead angle is further reduced, a larger welding flux contact surface is provided, higher strength is obtained, and welding fluxes are saved.

Preferably, the radius of the arc groove is equal to one third of the maximum thickness of the web, and the radius of the arc groove is twice the radius of the arc groove. So design, the more than or equal to of arc groove forms 45 slopes, the arc slot forms more than or equal to 30 degrees slopes, and the radian is decided by web thickness to be convenient for weld crater wedging near the welding seam, and then guarantee submerged arc hot melt solder's construction quality.

Preferably, the flange plate is provided with welding grooves perpendicular to the web plate on two sides of the arc-shaped groove. By the design, the welding groove is used for the welding flux in an inner infiltration state, so that the welding strength between the web plate and the flange plate is further enhanced.

Furthermore, the bottom of the welding groove is a slope. By the design, the solder is concentrated towards the direction of the web plate groove.

Furthermore, the welding groove is triangular and penetrates inwards to the arc groove. By the design, the reinforcing structure can be communicated with the welding seam gap, so that the solder forms a reinforcing structure similar to the embedded triangular reinforcing rib.

Preferably, the web is a corrugated web. So design, reinforcing web intensity uses the relative technology of ripple web complicated, and the groove can be beaten before the web is buckled, and the arc slot then need extend with the web with the curvature, but bearing capacity and the compressive property of improvement H shaped steel flange board that this kind of structure can be very big.

The process flow comprises the following steps: firstly, milling grooves of a web plate groove and a flange plate, then assembling and fixing on a tire membrane, and finally performing spray material submerged welding, wherein the welding process can be mechanical double-side butt welding, manual single-side welding and turning-over and reversing welding until four welding lines are welded.

The utility model relates to a full penetration welding H shaped steel of footpath poor arc chute welding seam has realized that the no dead angle of web and flange board concatenation welding seam is filled and complete penetration welding is even, for current welded structure, this H shaped steel arc has not only obtained higher joint strength through bigger solder contact surface and infiltration degree of depth, and the welding seam clearance that two cambered surfaces formed in addition more saves the solder.
