Manitowoc Cranes performs large amounts of welding to manufacture a crane. Preheat is required to have quality welds for critical structures of the crane. The cost and time for preheat can be very high. To be competitive in the crane market, Manitowoc needs quality welds without adding unnecessary extra cost and time required for preheat. This study will determine if preheat is required, and if so, how much. The first step will be to calculate preheat by theoretical calculations. The second step will determine calculation accuracy by welding and mechanical testing. Finally, preheat needs will be determined using the calculations and testing data. Students will be tasked with literature searches to determine the best welding preheat calculations. Students will also be tasked with designing test procedures to evaluate welds with various preheat requirements. Manitowoc will provide all materials for testing.
