Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and more particularly to a device for controlling welding deformation of a stainless steel flat sheet. Background Art

[0002] The inner walls of the cargo tanks of stainless steel chemical tankers are constructed of stainless steel. To reduce the weight of the vessel, the stainless steel plates are often relatively thin (6-10 mm). Since stainless steel cannot be deformed after welding using the same special properties as carbon steel, and shipowners generally require high flatness in stainless steel cargo tanks, welding deformation of stainless steel requires advanced control. In particular, when stainless steel panels are assembled and welded to form a stainless steel sheet, conventional welding of the bulb flat steel onto a flat jig results in significant wave and arc deformation, exceeding the permitted flatness. Therefore, in-depth research on stainless steel welding on ships is necessary to reduce deformation during welding and the subsequent deformation workload. Furthermore, existing jigs designed specifically for controlling stainless steel sheet welding are only suitable for welding a single specification of stainless steel sheet (different thicknesses of stainless steel exhibit different deformation curvatures after welding). This means that welding stainless steel sheets of different sizes often requires dismantling the old jig and rebuilding a new one. This leads to repeated dismantling and remanufacturing of the existing jig, resulting in wasted resources, high overall costs, long construction times, and a limited range of applications.

[0060] 2) Stainless steel panels are marked on the flat frame, and the longitudinal bone flat steel 22 is positioned and fixed by spot welding according to the process requirements (only one side of the longitudinal bone is spot welded). The longitudinal bone should be straightened and positioned and installed, and forceful assembly is prohibited;

[0061] 3) The stainless steel sheet 23 (stainless steel plate + longitudinal bone) is hoisted onto the anti-deformation curved surface support of the specially designed device for controlling the welding deformation of the stainless steel flat sheet.

[0062] 4) Use a template to check and adjust the angle of the longitudinal spherical flat steel 22, and spot weld the other side of the longitudinal spherical flat steel;

[0063] 5) Adjust the angle of the welding trolley to align with the welding position, start welding according to the welding process requirements, pay attention to the trolley to prevent welding deviation, for long welds, weld from the middle to both sides, and weld single longitudinal bones at intervals;

[0064] 6) After the welding process is completed, the tire is removed and transported by multi-point lifting and placed on a flat tire frame to release stress;

[0065] 7) After checking the flatness of the stainless steel sheet 23, a special bracket is used to transport it to the next process.
