The most problematical issue with welding robots is part quality. Robotic systems are designed to repeat the same sequence of events. If the robot system has been damaged, repeatability can become an issue.
Robotics systems sold feature a repeatability measurement and that should be taken into account along with payload and reach requirements. Used robots should be tested for accuracy and repeatability during the reconditioning process. When performing properly, robotic systems are more reliable and produce parts far superior in quality than manually welded parts. Touch sensing and seam tracking can be used to compensate for weld joints that are not static, but robots are limited by the laws of physics. The use of quality equipment in conjunction with robots improves the part fit-up. Attention should be paid to lasers, welding and cutting torches, welding power supplies, raw consumables, and other variables that could lead to a loss of quality in the finished product.
