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.
Before Commencement and during the ceremony the tassle is worn on the right side, then flipped to the left. zbeckabee. The tassel is worn on the right side before the degree is conferred. It is customary to change the tassel from the right to the left side after the degree is conferred. However, doctoral and MFA candidates will wear a gown, cap, and tassel.

When the tassel is flipped is dependent upon school tradition. http://www.brownielocks.com/graduation.html. http://www.cgu.edu/pages/2982.asp.
