In welding, the concept of optimisation had been used, till date, to serve two specific purposes. To obtain any desired weld attributes, a set of required optimal input parameters could be determined utilising the principle of optimisation. To establish an input–output relationship of a welding process accurately, which might be essential to automate it, the tools for optimisation had been used extensively. These optimisation problems were formulated as either a single-objective or multi-objectives or many-objectives ones. Both traditional and nature-inspired optimisation tools were used for the said purposes. This paper provides an extensive review on the role of optimisation in welding. Some research areas have also been identified for future study.

迄今为止，在焊接中一直使用优化的概念来满足两个特定的目的。为了获得任何期望的焊接属性，可以利用优化原理来确定一组所需的最佳输入参数。为了准确地建立焊接过程的输入-输出关系（这可能是使其自动化必不可少的），优化工具已得到广泛使用。这些优化问题被表述为单目标或多目标或多目标。出于上述目的，使用了传统的和自然启发的优化工具。本文对优化在焊接中的作用进行了广泛的综述。还确定了一些研究领域以供将来研究。
