Optionally, as shown in fig. 2, fig. 2 is a flowchart illustrating detailed steps of an outer plate mark implanting welding process provided in an embodiment of the present invention, and the implanting welding process is described in detail below, and specifically includes the following steps:
and S1, punching points on the outer plate 2 according to the mark-shaped contour 11.
Punching points are punched through sample punching on the outer plate 2, so that welding positioning of welding beads is facilitated, and welding accuracy is improved. Further, the step S1 specifically includes:
s11, drawing the logo shape outline 11 on the sheet 1;
s12, drawing a plurality of sample punching points 111 at intervals along the mark-shaped contour 11;
s13, fixedly attaching the paper 1 to the outer plate 2;
and S14, punching points are punched on the outer plate 2 according to the positions of the punching points 111.
The marking shape outline 11 is drawn on the paper 1 in advance, a plurality of sample punching points 111 are drawn according to the marking shape outline 11, then the paper 1 is fixedly attached to the outer plate 2, and finally, the sample punching points are punched on the outer plate 2 according to the positions of the sample punching points 111, so that the sample punching point arranging efficiency is improved, and the accuracy of various punching point positions is ensured. In this embodiment, to improve the aesthetic property of the mark, the plurality of punching points are disposed at equal intervals, and the distance between two adjacent punching points is 8mm-12mm, specifically 8mm, 9mm, 10mm, and so on.
And S2, selecting the specification of the welding bead according to the design drawing.
As shown in fig. 3 and 4, the welding bead is a screw 3 with a diameter of 3mm-12mm and a height of 3mm-5mm, and the screw 3 is made of stainless steel to enhance corrosion resistance. Specifically, in this embodiment, the design paper requires a bead width of 5mm and a bead height of 2 mm. However, the height of the welding nail chuck of 2mm is difficult to clamp, so that the height of the welding bead is actually adjusted to 3mm, and in addition, the number of the welding nails with the diameter of 5mm on the market is small, so that the diameter of the screw 3 is actually adjusted to 6mm, namely, the screw 3 is finally determined to be M6 x 3. The marks of the outer plate 2 are distributed outside the cabin and are easily corroded by seawater, so the screw 3 is made of 316L stainless steel with strong corrosion resistance. Of course, in other embodiments, the size and material of the screw 3 may be selected according to the requirement, and is not limited to this embodiment.
Furthermore, the screw 3 is provided with a flange 31, and the flange 31 and the outer plate 2 are welded and fixed so as to increase the welding area of the screw 3 and the outer plate 2, improve the welding strength and reduce the nail dropping rate. Certainly, in this embodiment, a welding manner of a capacitive energy storage stud welding machine is adopted, and a "boss type" arc striking tip 311 is arranged on one side where the flange plate 31 and the outer plate 2 are welded so as to conduct current during welding, and meanwhile, the "boss type" arc striking tip 311 has a higher success rate than the existing plum blossom tips, so that an operator can grasp the arc striking tip more easily.
To facilitate the painting of the screw 3 after welding, the end of the screw 3 facing away from the striking tip 311 is rounded. Optionally, the fillet radius is 0.5mm, and in other embodiments, the fillet radius of the screw 3 may be selected according to the size of the screw 3, which is not limited to this embodiment.
And S3, determining the discharge voltage of the capacitive energy storage type stud welding machine according to the specification of the welding bead.
The working principle of the capacitive energy storage type stud welding machine is as follows: the single 220V current is input, the capacitor stores energy firstly, then the control system controls the capacitor to discharge, the discharge voltage can be adjusted according to the welding requirement, and the screw 3 arranged on the welding gun can be welded in the sample punching point on the outer plate 2 at the moment of capacitor discharge. In the present embodiment, according to the selected size (M6 × 3) of the screw 3, the weld seam forming quality between the screw 3 and the outer plate 2 is best when the discharge voltage is tested to be 80V-90V. Of course, in other embodiments, the discharge voltage of the capacitive energy storage stud welding machine may vary accordingly depending on the selected size of the screw 3. Specifically, the discharge voltage is selected according to the following table 1.
TABLE 1
| Screw size (mm) | Discharge voltage (V) |
| M3 | 55-65 |
| M4 | 65-75 |
| M5 | 70-80 |
| M6 | 80-90 |
| M8 | 130-160 |
| M10 | 160-180 |
| M12 | 180-200 |
As can be seen from table 1, the discharge voltage of the capacitive energy storage type stud welding machine increases correspondingly as the diameter of the screw 3 increases, so as to ensure the welding strength. The operator can quickly determine the discharge voltage according to the table 1, which is very convenient.
And S4, mounting the welding bead on a welding gun.
Alternatively, the screw 3 is clamped and fixed to a welding gun by a clamp to facilitate welding.
And S5, providing discharge voltage for the welding gun by adopting the capacitive energy storage type stud welding machine so as to implant welding beads into the sample punching points to form marks.
The capacitor energy storage type stud welding machine is adopted to provide discharge voltage for the welding gun, so that the welding voltage can be maintained in a reasonable range required by welding, the welding quality is ensured, and the attractiveness of the mark is improved.
In summary, the embodiment of the invention provides an outer plate mark implant welding process, which overcomes the defects of the existing CO2The defects of craters, shrinkage cavities and the like caused by semi-automatic welding or manual electric arc welding are overcome, and meanwhile, less smoke is generated, so that the welding accuracy is improved, and the mark appearance is more uniform and attractive.
