Inverse Heat Transfer Analysis on Dual Beam Laser Welding Process

Precision laser welding is an innovative manufacturing technology in aerospace, automobile, energy, and microelectronics industry. There is a great need of better understanding, theoretical and computational analysis, and experimental characterization to optimize laser-material interactions. Dual beam laser opertation is an advanced technique in laser industry. The secondary or auxiliary laser beam can be used for in-situ post processing of the material or better control of process temperature, which cannot be easily achieved by a single-beam operation, especially for additive manufacturing. This project focuses on predictive modeling and uncertainty analysis from the perspective of inverse engineering for temperature control during dual beam laser operation.
