INFLUENCE OF KEYHOLE TIG WELDING PARAMETERS ON WELD GEOMETRY OF NEWLY-DEVELOPED SUPERALLOY VDM ALLOY 780

A. Ariaseta, Sweden; N. Sadeghinia, Sweden; J. Andersson, Sweden

The effect of Force TIG welding process parameters on the weld geometry, porosity, and cracking susceptibility of new nickel-based superalloy VDM 780 will be investigated. The results obtained in this work will be used to optimize the Force TIG welding process parameters that produce the VDM 780 weld that meets tight industrial quality criteria and with the lowest cracking susceptibility
