AI Technical Summary
Existing technologies for repairing welds in tanks containing molten metal suffer from several drawbacks. Weld defects are often located deep and close to the back side, making repair difficult. Furthermore, removing the inner wall refractory material is costly and challenging, leading to frequent rework and impacting the safe operation of the tank.
Weld defects are marked using non-destructive testing and treated with tools such as carbon arc gouging and grinding wheels. Externally, they are repaired by applying thin plates to the inner refractory lining, avoiding the removal of the refractory material. Ultrasonic testing and heat treatment are combined to ensure quality.
It enables rapid and low-cost weld repair, reduces process difficulty, avoids rework, and improves repair quality and tank safety.
