Example Embodiment

[0020] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific embodiments.
[0021] like Figure 1-Figure 6 As shown in the figure, a composite slab submerged arc welding-free removal arc ignition plate according to the present invention includes two composite blank steel plates 2, and the four corners of the two composite blank steel plates 2 are provided with a removal-free arc ignition plate 1. Four composite billet steel vertical bars 3 are arranged between the composite billet steel plates 2, and a slope 5 is provided on the removal-free arc striking plate 1, and the slope surface 5 is welded with the composite billet steel plate 2. The arc striking plate 1 is provided with a positioning groove 4, and two adjacent composite billet steel vertical bars 3 are welded in the same positioning groove 4; It's the next finisher.
[0022] Specifically, after the removal-free arc striking plate 1 is fixedly welded between the composite billet steel plate 2 and the composite billet steel vertical bar 3 by means of gas shielded welding, submerged arc welding of the composite blank can be carried out, so that the removal-free arc striking plate 1 can be welded by submerged arc welding. The welding of the board 1 is more convenient.
[0023] Specifically, as Figure 1-6 As shown in the figure, the outline structure of the positioning groove 4 and the slope surface 5 of the arc plate 1 without removing the Ninety degrees, the slope surface 5 is one hundred and thirty-five degrees; only four arc strike plates 1 need to be welded, and do not need to be removed, because the slope surface 5 of the arc strike plate 1 and the welding slope of the composite blank need not be removed. The shape of the mouth is completely fitted, and the slope surface 5 is one hundred and thirty-five degrees. It is not necessary to remove the upper and lower shoulders of the arc strike plate 1, and the upper and lower shoulders are trimmed. Welders perform spot-fixed welding, which makes the welding without removing the arc pilot plate 1 more convenient and faster. Since there is no need to remove the arc pilot plate 1, all four arc pilot plates 1 can be welded at one time. After the submerged arc welding is completed, it becomes a part of the weld bead. It saves worry and effort, improves efficiency, and the thickness of the arc ignition plate 1 is thicker than that of the conventional arc ignition plate, so it will not be broken down. The four arc ignition plates 1 that do not need to be removed are the arc ignition plates for this submerged arc welding , it is the next arc end plate, which improves the efficiency and quality of submerged arc welding. The slope surface 5 and the welding groove shape of the composite billet steel plate 2 are completely fitted, which is easy to weld. The positioning groove 4 is 90 degrees, which is convenient for welding. The four composite billet steel vertical bars 3 are enclosed in a rectangular frame, which is suitable for submerged arc welding and sealing welding of composite billets within the same height range of the composite billet steel vertical bars 3 .
[0024] Specifically, as figure 1 and Image 6 As shown, the removal-free arc ignition plate 1 can be welded to the four corners of the composite billet steel plate 2 at one time.
[0025] When the present invention is in use, only four arc striking plates 1 need to be welded without removing them, because the slope surface 5 of the arc striking plate 1 and the welding groove shape of the composite blank are completely matched, and the slope surface 5 is in the shape of the welding groove. One hundred and thirty-five degrees, the upper and lower shoulders of the arc striking plate 1 are not removed, and the angle is trimmed, which is completely fitted with the composite billet steel plate 2 and its groove, which is easy for submerged arc welding welders to spot-fix welding, so that the removal of the arc striking plate is unnecessary. The welding of the plate 1 is more convenient and quick. Since it does not need to be removed, all four arc plates 1 can be welded at one time without removing the arc pilot plate 1. After the submerged arc welding is completed, it becomes a part of the weld bead, which saves worry and effort, improves the efficiency, and eliminates the need to remove the pilot plate. The thickness of the arc plate 1 is thicker than that of the conventional arc ignition plate, and it will not be broken down. The four non-removal arc ignition plates 1 are the arc ignition plate of this submerged arc welding and the arc end plate of the next one. In order to improve the efficiency and quality of submerged arc welding, the slope surface 5 completely fits the shape of the welding groove of the composite billet steel plate 2, which is easy to weld. It can be used for submerged arc welding and sealing welding of composite billets in the same height range of composite billet steel bars.
