In this paper the author describes the welding of
Monel and the heat-treatable modification known
as ' K' Monel. The alloys can be welded by all
normal techniques, but the advantages and limitations
of fusion, resistance and pressure welding for various types of fabrication are covered in detail.The cause and cure of various welding defects are described and the procedure for avoiding corrosion,particularly of the cavity type, in fabricated structures is outlined.
A number of specific examples of defective welds
in Monel and ' K' Monel are given and the reason
for each is detailed in technical terms
