Which domestic welding robot system integrators are more professional? Or the industry leader?

At present, Kunshan Huaheng and Chengdu welding research David are relatively big. I also know Zhuhai Gude, Jinan SMIC Lucent, Harbin Yangfei Automation, Tianjin Biyang Technology, etc. Of course, these are basically not comparable to OTC and fanuc. The two robot manufacturers do their own integration, and the OTC welding machine is good and cost-effective. Fanuc uses Lincoln welding machine, Panasonic's own robots and welding machines are also good, and others, such as cloos, are made, but the price is high.
