Abstract
The invention discloses a kind of frame vehicle longeron stage casing buttress brace welding procedure, mainly include step 1) longeron stage casing buttress brace bevel angle is reduced, increase root face length；2) two welding beads of longeron stage casing buttress brace or so are divided into some sections and intersection is intermittently welded；The present invention solves longeron stage casing buttress brace and inclined problem is also easy to produce in welding process, on the premise of weldquality is ensured, by improving welding procedure, adjustment welding sequence, effectively reduce the welding deformation amount of longeron stage casing buttress brace, the depth of parallelism of longeron stage casing buttress brace and longeron lower wing plate is controlled within 1.5mm, the qualification rate of product is improve, it is ensured that the vehicle performance of frame vehicle.
Description
Technical field
The invention belongs to Welded field, and in particular to a kind of frame vehicle longeron stage casing buttress brace welding procedure.
Background technology
Frame vehicle mainly coordinates for long-distance transportation with container, main by being welded to connect between each several part, wherein,
Longeron stage casing buttress brace is double webs, is about 4~5.5m, is double-deck twice weldering during welding.
In the prior art, using monosymmetric welding method from the beginning to the end after longeron stage casing buttress brace solid point, more to tail
Its accumulative deflection of portion is bigger, causes after the completion of welding, and the wing plate of longeron stage casing buttress brace is inclined seriously, with longeron lower wing plate
It is not parallel.Due to that cannot be carried out after the completion of part welding, effective adjusting is orthopedic, not only have impact on the group butt welding of miscellaneous part
Connect, also reduce the mechanical property of vehicle.
The content of the invention
In view of this, can effectively control longeron stage casing buttress brace welding deformation it is an object of the invention to provide one kind, carry
The welding procedure of frame vehicle vehicle performance high.
To reach above-mentioned purpose, the present invention provides following technical scheme：A kind of frame vehicle longeron stage casing buttress brace Welder
Skill, mainly includes the following steps that：
1) longeron stage casing buttress brace bevel angle is reduced, increases root face length；
2) two welding beads of longeron stage casing buttress brace or so are divided into some sections and intersection is intermittently welded.
Further, the step 1) in, longeron stage casing buttress brace bevel angle is 45 °, root face 2mm long.
Further, the step 2) in, longeron stage casing buttress brace or so every welding bead of two welding beads is divided into 7 sections, every section of weldering
Road 570~790mm long.
Further, the step 2) in intersection be intermittently welded order be：Left welding bead 4 → backhand welding of section road 6 → backhand welding of section road
Section 2 → left welding bead section 7 → left welding bead 1 → backhand welding of section road section 4 → left welding bead section 5 → left welding bead 3 → backhand welding of section road 9 → backhand welding of section road
3 → backhand welding of section road, 1 → backhand welding of section road section 7 → left welding bead section 2 → left welding bead section 6.
The beneficial effects of the present invention are：Solve longeron stage casing buttress brace and inclined asking is also easy to produce in welding process
Topic, on the premise of weldquality is ensured, by improving welding procedure, adjusts welding sequence, effectively reduces longeron stage casing and adds
The welding deformation amount of brutal, the depth of parallelism of longeron stage casing buttress brace and longeron lower wing plate is controlled within 1.5mm, improves product
The qualification rate of product, it is ensured that the vehicle performance of frame vehicle.
Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carries out
Explanation：
Fig. 1 is structural representation of the invention；
Fig. 2 is longeron stage casing buttress brace structural representation；
Fig. 3 is longeron stage casing buttress brace welding sequence schematic diagram.
Specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As illustrated, the stage casing buttress brace welding procedure of frame vehicle longeron 1 in the present invention, mainly includes the following steps that：1)
Reduce longeron stage casing buttress brace 2 bevel angle α, increase root face length b；2) by 2 or so two welderings of longeron stage casing buttress brace
Road is divided into some sections and intersection is intermittently welded.
Specifically, single double V-groove angle [alpha] in the present invention is reduced into 45 ° by 60 ° of the prior art, root face b by
1mm extends to 2mm, and the bevel angle after improvement diminishes, and root face becomes big, on the premise of root of weld fusion effect is ensured
The loading of weld metal is reduced, speed of welding is improved, is effectively prevented in welding process because weld metal shrinks
The welding deformation for causing.
In the present invention, longeron stage casing buttress brace or so every welding bead of two welding beads is divided into 7 sections, and every section of welding bead is long by 570~
790mm, the preferably each section a length of 700mm of welding bead；Intersection is intermittently welded order：Left welding bead 4 → backhand welding of section road 6 → backhand welding of section road section
2 → left welding bead section 7 → left welding bead 1 → backhand welding of section road section 4 → left welding bead section 5 → left welding bead 3 → backhand welding of section road 9 → backhand welding of section road section
3 → backhand welding road, 1 → backhand welding of section road section 7 → left welding bead section 2 → left welding bead section 6.By rationally arrangement welding sequence, weldering can not only be made
Connect rapid heat dissipation, at the same under the influence of not road weld seam welding, be effectively prevented the generation of welding deformation.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment to be described in detail the present invention, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
