There is secondary heat input, increase welding deformation and residual stress in the program, it is bad to be easily caused welding quality, Jin Erying
Ring the assembling effect hanging and its bearing capacity, meanwhile, the speed of welding of the program is relatively low.
Therefore, it is necessary to improve to existing assembling mode, change welding manner and combination, reduce second heat
Input and welding capacity, to reduce secondary input and the welding deformation of heat, improve welding efficiency and quality it is ensured that beam welding is strong
Bearing capacity after degree and assembling, improves the security of car load.
Content of the invention
In view of this, it is an object of the invention to provide a kind of hang crossbeam and longeron packaging technology, second heat can be reduced defeated
Enter and welding capacity.
The purpose of the present invention is to be realized by below scheme：
Hang crossbeam and longeron packaging technology, comprise the following steps：
I, seam：The two ends of crossbeam are inserted in the U-type groove of a U-shaped connecting plate respectively, takes the flat of one layer of one weldering
Both seam are combined by fillet welding for crossbeam：First weld short weld seam and weld long weld seam again；First weld same type weld seam, then weld another
One type welding seam；Finally weld girth joint；
II, riveting：By crossbeam combination and longeron riveting.
Further, the welding condition of step I：Welding current 200-220A；Weldingvoltage 23.5-23.8V；Speed of welding 8-
10mm/s；Protective gas is 99.999%Ar；Flow is 18-22L/min；Welding gun and 5 ° -20 ° of vertical direction inclination angle.
Further, before step I, it is additionally provided with polishing and preheating step before weldering.
Further, between step I and step II, it is additionally provided with postwelding reconditioning step.
Further, described U-shaped connecting plate is provided with welding reinforced hole on two side walls of U-type groove, in step I, also wraps
Include the periphery of welding reinforced hole and the process of crossbeam seam.
The invention has the beneficial effects as follows：
The present invention improve hang crossbeam welding structure after, by two-layer twice weldering be modified to one layer one weldering decrease secondary
Heat input and welding capacity, reduce welding deformation and residual stress, under conditions of ensure that weld strength, reduce welding bead and are holding
Stress during by dynamic load and static load, frame cross being produced, reduces the welding bead and heat affected area crack-sensitivity when carrying
Property, welding bead form meets (PF) by vertical-up welding and is improved to that flat fillet weld (PB) is more beneficial for the shaping in welding bead molten bath and welder operates,
Avoid the impact to welding bead molten bath for the molten drop gravity；Change the welding bead stress types suffered when carrying, meet intensity requirement
On the premise of avoid the impact to workpiece for the weld defects such as welding deformation and welding residual stress it is ensured that hang crossbeam group weldering
Rear bearing capacity is it is ensured that the stability of car load, security and practicality.
Other advantages of the present invention, target and feature will be illustrated to a certain extent in the following description, and
And to a certain extent, will be apparent to those skilled in the art based on to investigating hereafter, or can
To be instructed from the practice of the present invention.The target of the present invention and other advantages can be realized by description below and
Obtain.
Brief description
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with accompanying drawing the present invention is made into
The detailed description of one step, wherein：
Fig. 1 is the schematic diagram of crossbeam and U-shaped connecting plate welding position；
Fig. 2 is the schematic diagram of crossbeam and U-shaped connecting plate welding sequence.
Specific embodiment
Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.It should be appreciated that preferred embodiment
Only for the present invention is described, rather than in order to limit the scope of the invention.
The a kind of of the present embodiment hangs crossbeam and longeron packaging technology, comprises the following steps：
1) prepare longeron one；One, crossbeam and U-shaped connecting plate two pieces, it is as illustrated, the U-type groove two of U-shaped connecting plate
Welding reinforced hole is provided with the wall of individual side, U-type groove bottom is provided with multiple riveted holes.
2) cleaning polishing is carried out to the position of need welding, then preheated, wait to be welded.
3) two ends of crossbeam are inserted respectively in the U-type groove of a U-shaped connecting plate, the flat fillet weld taking one layer of one weldering will
Both seam are combined for crossbeam：First weld short weld seam and weld long weld seam again；First weld same type weld seam, then weld another type
Weld seam；Finally weld girth joint；Specific welding position is as shown in Figure 1.
Welding condition：Welding current 200-220A；Weldingvoltage 23.5-23.8V；Speed of welding 8-10mm/s；Shielding gas
Body is 99.999%Ar；Flow is 18-22L/min；Welding gun and 5 ° -20 ° of vertical direction inclination angle；
Specific welding sequence：
U-shaped connecting plate and crossbeam are placed as shown in Figure 2：First burn-on and hold the side seam 1 of outer surface, then weld table in lower end
The side seam 2 in face, then welds the vertical welded seam 3 of inner surface visible surface again, finally weldering welding reinforced hole；Afterwards turn over, repeat
Above-mentioned steps.
