The Co-Cr alloy presented an excellent weldability.

Lengthening, Cracking and Weldability Problems of Fe Ni

Vol.8, No.2 Lengthening, Cracking and Weldability Problems of FeNiCr Alloy Tube 134. One of the Furnaces of an Olefin plant had experienced tubes problems repeatedly consisting of lengthening, cracking and weldability. The 4th pass radiant outlet tube made of the latest Microstructure Development during Dissimilar Welding:The study on laser welding of Cu-Ni [22] showed that melting begins and progresses to a larger extent in the Ni side due to its lower thermal diffusivity compared to Cu. Melting of Cu occurred mainly by the convective heat transfer to this side by the Marangoni flow. The computed weld pool shape and the species mixing patterns were found
