The following tests are described:
The above tests can provide information about the hot cracking sensitivity of parent materials, weld metals and weldments. Assessment is based upon the measurement of the brittle temperature range (BTR) where hot cracks occur.
This document applies primarily to austenitic stainless steels, nickel-, nickel-base and nickel-copper alloys, weldments and welding consumables. However, the principles can be extended to other materials such as aluminium alloys and high-strength steels.
