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 reinforcing rib 2, welding torch one path point A5 and welding torch two path point A9...

Abstract

The invention provides a horizontal fillet welding seam angle-wrapping process suitable for automatic welding, and the horizontal fillet welding seam angle-wrapping process is suitable for unit vertical welding in a ship building process, adopts gas-shielded welding to carry out automatic welding to complete horizontal fillet welding seam angle-wrapping welding for a bottom plate and reinforcing ribs, and belongs to the technical field of gas-shielded welding automatic welding. According to the technical scheme adopted by the invention, two robots drive two welding guns; arcs are initiated from the two sides to drive the welding guns to move to the middle of the reinforcing ribs, so that angle-wrapped welding is completed, welding seams are full, and dimensions of the welding seams meet requirements. The horizontal fillet welding seam angle-wrapping process provided by the invention has the positive effects of reducing times of overlap welding, arc initiating and arc extinguishing, avoiding defects, reducing interferences of the welding guns and workpieces, especially reinforcing ribs with circular-arc holes in end parts, expanding automatic welding cover range and greatly simplifying trial teaching workload. The horizontal fillet welding seam angle-wrapping process is wide in scope of application, easily realizes automatic welding, has relatively low requirements on workpiece pairing, and improves welding quality and working 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...
