With the development of aerospace, marine engineering, and other industries, aluminum alloys are widely used. There are welding defects in the traditional welding method for welding aluminum alloys. This article discusses an advanced method based on traditional welding methods, which can effectively reduce the probability of defect occurrence. In these methods, welding with an external magnetic field can promote the formation of equiaxed crystals during crystallization, grain refinement, and improved weld performance. The porosity is reduced and the sensitivity to thermal cracking is reduced. The future development direction of aluminum alloy welding is discussed at the end of the article.
