英文摘要：

To improve the utilization efficiency of resources and energy in the process of welding technology, and reduce carbon emissions, this paper analyzes the mechanism of carbon emissions based on the welding process from mate- rial, energy and waste. Welding carbon characteristic function is established by using the theory of welding formula and mathematical relationship, the carbon emissions influence factor of reflow solder welding equipment were analyzed and the genetic algorithm （GA） optimization model is established to find out the optimal solution.
