Industrial robot (robotic arm) welding refers to: using industrial robots to replace traditional manual work to complete the work of spot welding, arc welding, etc. This welding method uses the characteristics of industrial robots such as precision, stability and efficiency to significantly improve the quality of welding. However, in the welding work of multiple varieties of workpieces (or products), since industrial robots can only perform tasks rigidly according to the engineers' plans. Therefore, engineers need to deploy the motion trajectory, posture, and welding method of industrial robots separately for different workpieces. This will consume a lot of deployment time and generate extremely high industrial deployment costs. Flexible welding is based on Mooma's core technology-robot application intelligent delivery system, which realizes the unmanned flexible welding operation of industrial robots (robotic arms). Through artificial intelligence technology, industrial robots can be autonomously programmed according to the welding requirements of different workpieces (or products), and the motion trajectory, posture, and welding method of industrial robots can be adjusted to complete welding operations for different workpieces (or products). This not only reduces the process of engineers manually deploying industrial robots (robotic arms), reduces the dependence of industrial robots (robotic arms) deployment on engineers, but also greatly shortens the production deployment time. At the same time, it helps companies meet the needs of rapid line and production changeovers for small-batch production of multiple varieties, thereby reducing costs and increasing efficiency.
