Case Study 1: Motorcycle Production Line

An exemplary implementation of welding robots can be seen in a project involving 21 units of QJRH4-1A welding robots and 6 units of QJRB20-1 handling robots in a motorcycle production line. The project’s success was further highlighted by the robots’ adherence to strict quality standards, having passed the CE test and ISO 9001: 2015; this commitment to quality is supported by a $10 million investment in high-standard testing machines, ensuring the welding robots‘ precision and dependability. These welding robots significantly increased productivity and reduced labor costs, illustrating the transformative impact of robotic welding in the automotive sector.

Case Study 2: Fitness Equipment Welding Project

Another compelling case study is the use of QJRH4-1 robots and single-axis positioners in a fitness equipment welding project. The QJRH4-1 robot, with its 4kg load capacity, repetitive positioning accuracy of ±0.03mm, and an armspan of 1410.5mm, exemplifies the advanced capabilities of modern welding robots. Synchronized movement of the welding robot and turntable resulted in smoother, more stable, and tighter welding seams; the exceptional quality and convenience of use of these welding robots demonstrate the potential of robotic welding in a range of manufacturing situations.

Future Trends in Robotic Arc Welding

Robotic arc welding looks like it will keep getting better. Improved quality, flexibility, and efficiency of manufacturing processes will ensure robotic welding’s position as an essential part of industrial production. New developments in welding robots and turntables should lead to even more inventive methods of satisfying the diverse and constantly changing demands of various industry sectors.


From the production of automobiles to fitness equipment, modern welding robots and turntables have undoubtedly changed the face of manufacturing and ushered in a new era of productivity and accuracy in production. As these technologies continue to advance, the industrial sector will inevitably benefit more from them, representing the beginning of a time when automated welding will be synonymous with superior manufacturing.
