Buttering is one of many methods used to reduce the hardening effects inherent to in-service and rapid cool rate welding. The standard industry practice is to weld a layer of low-hydrogen weld metal matching the base material before commencing with the in-service weld. This study will examine the effect that buttering has on the weldment and parent material hardness, while keeping carbon equivalent and cooling rates constant. It will also address how various codes apply to in-service welding.
Speaker – Morgan Dull EIT, CET
Morgan Dull graduated from the Welding Engineering Technology program at SAIT in 2005. He worked in Calgary and Ft. McMurray doing mechanical testing, Quality Control, as a Welding Technologist, and Welding Examiner. In 2008 he began a co-op degree program in Mechanical Engineering at the University of Victoria. He maintained involvement in the welding industry by continuing to work in quality control during his co-op terms. Morgan also worked on welding related projects for the Canadian Navy, an aircraft manufacturer, and on a military submarine. While at the University of Victoria he was a member of the Formula SAE team which involved TIG welding structural parts and engine components for a race car. In 2013 Morgan graduated UVic and has been with Red Flame Industries since that time.
