Embodiment approach

[0029] The two welding torches are welding torch one 3 and welding torch two 4 respectively.

[0030] Refer to attached figure 1 , when the group is welded vertically, the end of the rib 2 also needs to be welded to the bottom plate 1, the weld between the end of the rib 2 and the bottom plate 1, and the weld transition from the end to the normal horizontal fillet weld are defined as horizontal fillet welds Seam wrap fillet welds.

[0031] Refer to attached figure 2 , 3 4. In order to carry out corner welding in automatic welding, use two welding torches one 3 and two welding torches 4 in a posture parallel to the end of the reinforcing rib, such as figure 2 , 3 The posture shown; the two welding torches parallel to the end of the reinforcing rib are arranged symmetrically on both sides of the reinforcing rib;

[0032] Welding torch one 3 and welding torch two 4 respectively arrive at welding torch one path point A5 and welding torch two path point A9 on the reinforcing...

Abstract

The invention provides a process suitable for automatic welding of horizontal fillet welds, which is suitable for group vertical welding in the ship building process, uses gas shielded welding for automatic welding, and completes the horizontal fillet welds of bottom plates and reinforcing ribs, which belongs to gas shielded welding Automatic welding technology field. The technical solution is: two robots drive two welding torches, strike arcs from both sides at the same time, drive the welding torches to move to the middle of the reinforcing rib to complete the corner welding, the weld seam is full, and the weld seam size meets the requirements. The positive effects of the present invention: the times of lap welding, arc starting and arc closing are reduced, and defects are avoided; the interference between the welding torch and the workpiece is reduced, especially the reinforcing rib with an arc hole at the end, which expands the coverage of automatic welding , and greatly simplifies the workload of trial teaching; the invention has a wide range of applications, is easy to realize automatic welding, has relatively loose requirements on workpiece groups, and improves welding quality and work efficiency.

Description

technical field [0001] The invention provides a process suitable for automatic welding of horizontal fillet welds, which is suitable for group vertical welding in the ship building process, uses gas shielded welding for automatic welding, and completes the horizontal fillet welds of bottom plates and reinforcing ribs, which belongs to gas shielded welding Automatic welding technology field. Background technique [0002] Currently, during ship construction, small group welding of vertical parts is carried out in the machining workshop. Sub-stands are defined on a base plate (refer to figure 1 ), install multiple horizontal and vertical reinforcing ribs to enhance the strength of the workpiece. The ends of these ribs come in a variety of forms (refer to figure 1 ), it needs to be welded and connected to the bottom plate by gas shielded welding; the shipbuilding process requires that the end of the stiffener also needs to be welded to the bottom plate, the weld between the e...
