Life-Cycle Energy Analysis as a Method for Welding Joint Design
This paper briefly explains some of the theoretical issues associated with life-cycle energy analysis and then uses an Al-Cu dissimilar metals welding product case study to demonstrate its use in evaluating alternative design strategies for an energy efficient welding product. The energy consuming characteristic and the life-cycle model of welding product have been studied by the energy analysis method. The energy consumption model of welding product throughout life-cycle has been modelled. The energy properties of different welding method has been studied and described quantitatively by the energy analysis method of total life-cycle. The results show that an effective brazing technology is the key to improve the utilization ratio of energy.
