The welding of Monel & K-Monel

Abstract

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.
