Abstract
The invention belongs to the technical field of steel tube welding and specifically relates to a whole plate thick penetration welding method for an intersection joint of a circular tube. The method comprises the following specific steps that a, the intersection circular tube is cut through a intersection line, and the position of a cutting starting point is marked; b, a starting point of a base plate is identical to the cutting starting point of the intersection circular tube, and an installation datum line is drawn on the outer side of the base plate with the cutting starting point as a datum; c, the intersection circular tube is assembled, and the precision of the installation dimensions of the circular tube is ensured; d, the special-shaped intersection base plate is assembled and stuffed in form the tail portion of the circular tube, and the installation datum line of the base plate is made coincide with the datum line of the inner wall of the circular tube; e, secondary groove machining is conducted, and a groove is polished through a polisher to make the groove face smooth after groove machining is finished; and f, groove machining is conducted, and the intersection joint can meet the requirement of a whole plate thick penetration welding line. According to the method, the conditions that the side portion and the root portion of the circular tube can not achieve full penetration are avoided.
Description
Technical field
The invention belongs to steel-pipe welding technical field, be specifically related to the full thickness of slab method for weld-penetration welding of a kind of Circular Tubular Joints.
Background technology
Construction steel structure industry is in the stage of high speed development now, and steel construction enterprise is male also rises, and the welding technique of enterprise is important channel and the developing goal of welding for steel structure industry competition.Current large span stadiums, in conference and exhibition center's structure steel fabrication, there is a large amount of continuous line welding nodes, because pipe intersecting mouth is special-shaped irregular weld seam, be difficult to add backing plate welding, pipe caliber (diameter D≤600mm) less than normal simultaneously, workman cannot carry out pipe inside and carry out back gouging, cause this type node cannot reach the welding requirements of full thickness of slab penetration, can not meet the structure stress requirement of design, (fabrication cycle is long can only to pass through to adopt steel-casting, cost improves in a large number), or concept transfer design of having to take the second best (structure change, sensorial effects changes, cost improves).
The angle that the present invention never changes project engineering node structure is set out, there is provided a kind of Circular Tubular Joints full thickness of slab method for weld-penetration welding, the problem of the full thickness of slab penetration weld of intersection is solved from the aspect formulating new welding procedure, meet the tubular joint structure Structural Design Requirement of current steel construction, this case produces thus.
Summary of the invention
The object of the present invention is to provide the full thickness of slab method for weld-penetration welding of a kind of Circular Tubular Joints, the problem of full thickness of slab penetration cannot be reached in order to solve special-shaped intersection welding seam, thus meet design engineer's intersection node structure force request, be applied in engineering under the mode making this node no longer adopt steel-casting to make.
For achieving the above object, concrete technical scheme provided by the invention is: the full thickness of slab method for weld-penetration welding of a kind of Circular Tubular Joints, comprise following concrete steps: the cutting of a, intersection passes through pipe mutually, identify cutpoint position, and draw datum line in inner vertical in axis, this plays cutpoint and backing plate, and to play cutpoint be same position; B, backing plate start position with pass through pipe mutually and rise and cut position consistency, outside backing plate, draw installation reference line to play cutpoint for benchmark; C, assembling are passed through pipe mutually, and are guaranteed pipe installation dimension precision; D, assembling abnormity pass through backing plate mutually, fill in, backing plate installation reference line is overlapped with round tube inner wall datum line from pipe afterbody; The mode of e, employing gouge carries out secondary retaining wall on slope, adopts sander to polish to groove, make groove face fairing after retaining wall on slope; F, routinely melt-through weld technique carry out retaining wall on slope, and tubular joint can reach the requirement of full thickness of slab melt-through weld.
Further, described steps d, pipe caliber is greater than 200mm, length adopts hand to stretch into pipe adjustment when being less than 500mm, if pipe caliber is not more than 200mm, length is not less than 500mm and adopts elongated bar adjustment, makes backing plate and passes through pipe groove profile mutually and fit, be adjacent to welded pipe, then from outside, weldering positioned to backing plate.
Further, described step a, intersection cutting passes through pipe mutually, has identified cutpoint position, and draw in inner vertical in axis the datum line that length is 100mm backward, and this plays cutpoint and backing plate, and to play cutpoint be same position.
The present invention is compared to the beneficial effect of prior art: one, solve first special-shaped intersection can not full thickness of slab penetration welding a difficult problem, make design in not change structure form, preparation method situation carries out the making of the full thickness of slab penetration of energy intersection node, technical capability reaches the designing requirement of the intersection structure of domestic and international design engineer, improves the competitiveness of the technology in this respect of enterprise.
Two, avoid employing cast steel and make node situation, reduce cost of manufacture, shorten the making duration.
Next, by reference to the accompanying drawings present pre-ferred embodiments is described in further details.

Detailed description of the invention
As Figure 1-4, what the present invention disclosed is the full thickness of slab method for weld-penetration welding of a kind of Circular Tubular Joints, specifically comprise the steps: that the cutting of a, intersection passes through pipe mutually, identify cutpoint position, and draw 100mm position reference line in inner vertical in axis backward, this plays cutpoint and backing plate, and to play cutpoint be same position;
B, special-shaped intersection backing plate to be programmed, require this backing plate start position and pass through pipe mutually and rise and cut position consistency, outside backing plate, draw installation reference line to play cutpoint for benchmark;
C, routinely technology mode assembling passes through pipe mutually, guarantees pipe installation dimension precision;
D, assembling abnormity pass through backing plate mutually, fill in from pipe afterbody, backing plate installation reference line is overlapped with round steel inwall datum line, caliber is greater than 200mm, adopt hand to stretch into pipe adjustment when length is less than 500mm, other situations adopt elongated bar adjustment, make backing plate and pass through pipe groove profile mutually and fit, be adjacent to welded pipe, then from outside, weldering positioned to backing plate;
