Welding is the main processing method in manufacturing industry. The development of industrial manufacturing is advancing from manual welding to intelligent automation in an orderly way. In order to develop a modernized and high-quality staff,the enterprise encourages the staff to actively participate in the skill competition. In this paper,taking the welding assembly of Panasonic welding robot as an example,the structural characteristics of the specimen is analyzed. Based on the welding defects encountered by Panasonic welding robot in small components,such as edge bite,disconnection,lack of fusion,large size deviation of welding angle and overlap,the measures are formulated,including welding parameters,welding sequence,programming method and operation skill. By formulating and implementing the measures,it is guaranteed that the overall score results of appearance quality and internal quality inspection after welding can be above 85 points.
