[0002] As my country's share of the world's offshore wind power industry and shipbuilding industry increases, product manufacturing efficiency and quality requirements are also increasing. Welding cracks are the most harmful defect. In addition to reducing the load-bearing capacity of the welded joint, the sharp notch at the end of the crack will cause severe stress concentration, prompting the crack to expand, and eventually lead to the destruction of the welded structure, making the product scrapped, and even causing serious accidents, which runs counter to the requirements of the industry and enterprises.

[0003] After analyzing the causes of transverse cracks in welds fed back by nondestructive testing, it was found that most transverse cracks were caused by excessive hydrogen content. Combined with the fact that most manufacturers are located near the sea and use CO 2 Flux-cored welding wire is highly efficient. Many welding wires are not completed on the same day after opening and are continued to be welded the next day without any protection, which increases the probability of hydrogen-induced cracks in welding.
