Background

In the field of automated welding, during welding by argon arc welding, a weld is formed by melting and mixing a base metal and a welding material to be filled into a liquid metal, and the liquid metal is solidified in a subsequent cooling process. While the joint is made by heating to form a weld, this localized heating also creates a non-uniform temperature field, resulting in the prevalence of stress and distortion of the weld joint. The heat transfer to the parent material region also results in material property and texture changes, referred to as heat affected zones in the weld. In the case of high-strength steel and aluminum alloy, the heat affected zone portion may be softened or embrittled due to the temperature increase caused by the heat conducted from the weld joint portion, thereby degrading the performance of the welded joint. In order to solve this problem, the portion of the base material close to the weld is often subjected to auxiliary cooling by an auxiliary cooling method to reduce adverse effects. However, most of the existing cooling devices for automated welding have uneven cooling speed and slow cooling speed, so that it is difficult to eliminate the heat affected zone and the phenomenon of uneven material shrinkage is easily caused. Therefore, a new high-speed cooling device for automatic welding is needed to overcome the above technical drawbacks.
