A lot of problems appear because that there are many differences between traditional welding process and industrial robot welding process, such as type selection of industrial robots, welding power configuration, and welding parameter adjustment, etc. On the basis of analyzing links in welding services of industrial robots, a platform of networked service in industrial robot welding was designed in this paper including its architecture structure, function structure, and database. The welding services and technical supports of industrial robots could be provided through this platform, such as type selection of industrial robots, welding power configuration, and welding parameter adjustment, etc. The results showed that the difficulty of industrial robot welding application was reduced by using this platform. And the quality of industrial robot welding was improved.

Laser cutting is widely used in the automotive industry. Customers with diversified and personalized requirements increase, small batch production is becoming a trend. Low cost robot flexible laser cutting came into being, but the positioning accuracy of the robot is not high. In some small holes processing it can't meet the accuracy requirements, which limited its application. A new cutting method is presented in this paper. The servo motor controlled by high precision motion controller which drive precision cross slide which drives the laser head to holes cutting. The results showed that the new method improved the accuracy and speed of the small hole laser cutting, and the whole system has a high flexibility, takes up less space.
