WELDING RESEARCH SUPPLEMENTS

The Mechanism of Ductility Dip Cracking in Nickel-Chromium Alloys
Test results showed that ductility dip cracking in these alloys are caused by thermal and solidification stresses induced during welding and a local grain boundary stress generated during precipitation of partially coherent (Cr, Fe)23C6  carbides
G. A. Young et al.

Consumable Double-Electrode GMAW - Part II: Monitoring, Modeling, and Control
Using the developed interval control algorithm, closed-loop control experiments were conducted to verify the effectiveness of the proposed control system for the consumable double-electrode GMAW process
K. H. Li and Y. M. Zhang

Observation of Arc Start Instability and Spatter Generation in GMAW
Spatter gerneration due to arc start instability was monitored using the voltage and wire feeding rate and an electrode temperature model was developed
U. Ersoy et al.
