In large soft coal excavators, worn chain links are not replaced but repaired. In the affected areas, several centimetres of steel are often missing Previously, these areas were repaired by manual welding methods.
A new automated solution uses a welding robot in combination with the scanCONTROL 2700 compact laser scanner. The company, Mabotic Robotics & Automation, has developed a completely automatic solution. The profile of the places to be repaired is first scanned. The special software then calculates the optimum guidance of the welding robot in combination with the target data of the part. Using this solution, valuable working time and hours of manual welding is saved. The compact laser scanner offers an attractive price/performance ratio and is currently optimised for use on robots.
