激光点焊在焊接需要小的热影响区的小型和/或电气部件时是有益的。迄今为止进行的传热分析的建模忽略了所涉及的过程的热效率分析。当考虑焊接工艺的优化和成本效益时，这可能变得重要。因此，本研究进行开发的基础上的第一和第二定律的热力学焊接效率的表达式。该研究扩展到包括焊接过程中的实验研究，将第一和第二定律效率与所得焊缝的机械性能。
Laser spot welding is beneficial when welding small and/or electrical components where a small heat-affected zone is required. The modeling of heat transfer analysis carried out until now omits thermal efficiency analysis of the process involved. This may become important when optimization and cost effectiveness of the welding process is concerned. Consequently, the present study was conducted to develop expressions relevant to the welding efficiencies based on the first and second laws of thermodynamics. The study is extended to include an experimental investigation into the welding process to relate the first-and second-law efficiencies with mechanical properties of the resulting welds.
