Copper alloy clad steels have been used for vessels and other structures, e. q. heat exchanger, condenser, evaporator, particle accelerator, etc. 9/1 cupro-nickel clad steel has been often used for evaporator of sea water. Results of formability and weldability tests on clad steel hot-rolled with insert of nickel are described in the present report. The following are the results obtained from the examination. The clad steel exhibited a bond strength higher than the cladding after high temperature heating and severe deformation. No cracks were shown in bend test when welded by the TIG process with or without a buffer of monel or alminum bronze. Two kind of grain boundary infiltration were observed as reported by Matthews and Savage when these copper alloys except monel were deposited on steel. Peel out of the cladding and "dig" of base metal are often performed to prepare the weld groove, but a "dig depth" under 10% of base metal thickness did not result in reduction of joint strength.
