The remedies for welding defects in ships primarily involve preventive and corrective measures. Prevention refers to taking measures before, during, and after welding to avoid or reduce the occurrence of welding defects, while correction refers to taking measures to eliminate or mitigate the effects of...

In STB welding various defects occurs. These defected joints are rejected. This rejection increases the production time and production costs. The root causes for the defects are found and studied. The important parameters that affect the weld quality in STB were found. The suitable remedies are ...
Excessive hydrogen and dynamic bubbles also cause poor arc stability in the UWW process. Based on the previous study, the optimization of welding consumables and process parameters alone cannot effectively reduce the number of defects and improve the quality of an underwater wet welded joint. Thus...
焊接作为现代制造业中一种重要的连接方法,广泛应用于船舶、建筑、汽车及各种机械设备的生产。然而,焊接过程中不可避免地会出现各种缺陷,这些缺陷不仅影响焊接接头的质量,还可能导致整体结构的安全性问题。因此,了解钢材焊接缺陷的类型、成因及补救措施,对于提高焊接质量和延长产品使用寿命至关重要。
Finally, the current difficulties and potential remedies are discussed to supply an understanding on what still needs to be improved in the LAHW process. This comprehensive review is to offer guidance for those trying to reduce welding defects as they enhance the welding joints’ quality. This is...
