Development of Welding Alloy Formula for Wear-Corrosion Resistant Overlay

There is a strong market demand for welding filler metals to make surfaces that can resist both abrasive wear and chemical loss. The objective of this internship is to quickly design and formulate high-chromium submerged arc welding powder for overlay. The experimental core for this project involves selecting alloys and designing microstructure at the University of Alberta, welding testing at sponsor Trimay facility, and wear and corrosion testing of produced overlay at a commercial lab. The experimental tasks will be performed by considering interactions among chemical formulas, how the welding is done, changes in the metal, cracking or not cracking, how hard is the overlay, and how corrosion resistant it is. The formulas developed will greatly benefit Trimay in its quality of products and increased market share.
