The welding of high-strength steel thick plates has a certain hardening tendency. The super-long weld seam welding construction interval is long, the temperature control between layers is difficult, the weld seam cools relatively quickly, and welding cracks are prone to occur. Moreover, due to the super-long steel plate, the relative rigidity is low , the welding deformation caused by a large temperature difference is relatively large, and it is not easy to adjust, and the weldability of the ultra-long weld process of high-strength steel thick plates is poor. Therefore, effectively improving the problem of poor weldability of ultra-long welds in high-strength steel thick plates is a key issue to reduce welding defects and improve the first pass rate of butt weld flaw detection.
