For laser welds in thick section steel, the main cause of solidification cracking is the weld profile shape. The high depth to width ratio of laser welds causes restraint and means that high thermal stress acts across the weld where the solidification fronts meet, causing centreline cracking.
Two days later they will participate in a Rose Ceremony as the final step in their graduation process. While a rose is symbolic for many things, the School of Nursingâs Jasmine Clark says it has become a traditional event at UBC and a time-honoured tradition.
The Commencement ceremony takes place before final grades are posted. It is the studentâs responsibility to read all communications in Connect and to fulfill all degree requirements. Students who wish to change graduation to a different semester must submit an updated application. Final grades should appear in pathway by Friday, December 22. After grades are available, advisors will run a final audit to determine if all graduation requirements are satisfied. Students who do not satisfy all requirements must submit a new graduation application for a different semester in order to remain eligible for financial aid, continue taking classes, and be awarded their degree once completed.
