Sheet metal processing is a crucial step in mechanical manufacturing and one of the main trades in the mechanical manufacturing industry. As the manufacturing industry progresses, sheet metal parts are widely used due to their advantages such as light weight (using less material than steel of the same volume), high rigidity, complex shapes, high precision, and good surface quality. With the advancement of science and technology, the requirements for product performance and quality are continuously increasing, necessitating a constant improvement in production efficiency and labor productivity to meet this demand. Welding methods are extensively used in the manufacturing of various components or assemblies in frame structures.
