Description

Single face welding and double face shaping welding method
Technical field
The present invention relates to special-purpose vehicle welding technology field, the welding side of especially a kind of steel plate double-faced forming for splicing Method.
Background technique
Currently, most of special purpose vehicles produce on splicing steel plate all by the way of two-sided welding, that is, it is being soldered splicing Steel plate is spliced into overturning after the one side of steel plate, then welds other one side.In the welding process, it not only needs to expend more people Power, material resources increase production cost, reduce production efficiency, and needs to relocate welding after turnover panel, influence to weld matter Amount, it is easier to cause welding deformation, cause the later period assemble in there are errors, lead to phenomena such as doing over again.Due to needing to guarantee welding Quality, it is desirable that the welding technique of operator is very high, so that this traditional welding technique has very in terms of human resources Big limitation brings many inconvenience to the production of special purpose vehicle.
Summary of the invention
The problem to be solved by the invention is to provide a kind of single face welding and double face shaping welding methods, to solve existing welding by both sides Technical quality is difficult to ensure, high production cost, the low problem of production efficiency.
To solve the above-mentioned problems, the technical scheme is that this single face welding and double face shaping welding method includes using A kind of welding equipment carries out splicing welding to two blocks of steel plates;The welding equipment includes the welding machine equipped with welding gun, and the welding gun is just Lower section is equipped with the track for fixing steel plate, and the arc slot that its center is aligned with the plumb joint of the welding gun is equipped in the track, The welding machine, which is equipped with, controls the control unit that the welding gun is run along the track, and the welding of the welding gun is upside down and along described Orbital direction inclination;
Splicing welding includes: to be put into copper pad in orbit as datum level, on copper pad it is placed side by side two pieces on an equal basis The steel plate that δ millimeters of thickness keeps gap b millimeters between two blocks of steel plates, and welding gun welds while moving along track, from two blocks of steel Gap between plate forms the weld seam for being higher than two pieces of steel plate front and backs, completes the weldering of single-side welding double-side forming It connects;Wherein: weld seam is higher than steel plate front h1 < 2 millimeter, and weld seam is higher than steel plate back side h2 < 2 millimeter, and weld seam is in the positive width of steel plate + 2 millimeters of δ of c1=2 of degree, weld seam is in c2=b+2 millimeters of width of the steel plate back side.
In above-mentioned technical proposal, more specifically scheme may is that the welding of the welding gun upside down and along the track Direction tilts 15 °~20 °.
Further: when two pieces of steel plate thickness δ=3 millimeter, the gap b between two blocks of steel plates is 3 millimeters~3.5 millimeters.
Further: when two pieces of steel plate thickness δ=4 millimeter, the gap b between two blocks of steel plates is 3 millimeters~4 millimeters.
Further: when two pieces of steel plate thickness δ=5 millimeter, the gap b between two blocks of steel plates is 3.5 millimeters~4 millimeters.
Further: when two pieces of steel plate thickness δ=6 millimeter, the gap b between two blocks of steel plates is 4 millimeters~4.5 millimeters.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages:
After this single face welding and double face shaping welding method uses the track with arc slot and positioning to position two blocks of steel plates well, according to Steel plate thickness, between the parameters such as gap control welded seam, make single-sided welding that can complete double-faced forming well, both saved Human and material resources, improves welding efficiency, and can be accurately located steel plate, is unlikely to deform in welding, guarantees weldering Quality is connect, makes product firm and durable, and weld seam is beautiful.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention;
Fig. 2 is the A direction view of Fig. 1;
Fig. 3 is the welding line structure schematic diagram after welding fabrication of the embodiment of the present invention.
Specific embodiment
The embodiment of the present invention is described in further detail with reference to the accompanying drawing:
This single face welding and double face shaping welding method as shown in Figure 1, Figure 2, Figure 3 shows, it includes using a kind of welding equipment to two pieces Steel plate carries out splicing welding, steel plate 6-1 and steel plate 6-2.Welding equipment includes the welding machine 1 equipped with welding gun 3, is set immediately below welding gun 3 There are the track 4 for fixing steel plate, the arc slot being aligned equipped with its center with the plumb joint of welding gun 3 in track 4, welding machine 3 is equipped with control The control unit 2 that welding gun 3 processed is run along track 4, the welding of welding gun 3 tilt upside down and along 4 direction of track.
The splicing welding includes: that copper pad 5 is put into track 4 as datum level, placed side by side two on copper pad 5 The steel plate that δ millimeters of block condition of equivalent thickness, steel plate 6-1 and steel plate 6-2 keep gap b millimeters between two blocks of steel plates, and welding gun 3 is along track 4 It is welded while moving, forms one from the gap between two pieces of steel plates (steel plate 6-1 and steel plate 6-2) and be higher than two blocks of steel plates just The weld seam in face and the back side, as shown in figure 3, completing the welding of single-side welding double-side forming.
Wherein: weld seam is higher than steel plate front h1 < 2 millimeter, and weld seam is higher than steel plate back side h2 < 2 millimeter, and weld seam is in steel plate front + 2 millimeters of δ of width c1=2, weld seam is in c2=b+2 millimeters of width of the steel plate back side.It should ensure that when splice joint between two plates Distance b, in practical jigsaw, the size of b value depends on the thickness δ of plate, and plate is thicker, then b value is bigger, meanwhile, welding All impurity within the scope of 20 millimeters of welding edge, dust, rusty stain etc. should be removed before connecing.
The welding of welding gun 3 is 15 °~20 ° upside down and along 4 direction tilt angle R of track, R, two pieces of millis of steel plate thickness δ=3 Meter Shi, the gap b between two blocks of steel plates are 3 millimeters~3.5 millimeters;When two pieces of steel plate thickness δ=4 millimeter, between two blocks of steel plates Gap b is 3 millimeters~4 millimeters;When two pieces of steel plate thickness δ=5 millimeter, the gap b between two blocks of steel plates is 3.5 millimeters~4 millis Rice;When two pieces of steel plate thickness δ=6 millimeter, the gap b between two blocks of steel plates is 4 millimeters~4.5 millimeters.Here R=15 °, δ=4 Millimeter, b=3.5 millimeter, h1=1.7 millimeter, h2=1.6 millimeter, c1=10 millimeter, c2=5.5 millimeter.In the actual operation process, may be used Just can guarantee the beautiful, uniform of molding weld seam according to the size for adjusting parameters situations such as plate thickness.
After this single face welding and double face shaping welding method uses the track with arc slot and positioning to position two blocks of steel plates well, According to steel plate thickness, between the parameters such as gap control welded seam, make single-sided welding that can complete double-faced forming well, both Human and material resources is saved, welding efficiency is improved, and steel plate can be accurately located, is unlikely to deform in welding, is protected Welding quality is demonstrate,proved, makes product firm and durable, and weld seam is beautiful.
