Recently, the growing needs for higher standards of tensile strength impact value in severe conditions are strongly demanded in the field of shipbuilding, offshore structure and various types of industries. Especially, capability in weld zone after PWHT (Post Weld Heat Treatment) is increasingly demanded by customers.
Generally, a significant decrease in impact value and tensile strength after applying PWHT has caused many limitations on its usage in spite of its great welding efficiency comparing to other welding consumables.
HWC newly developed and began to provide...
