Abstract Abstract In the actual welding production process, there is often a change in the angle of the welding groove. Primal problem of that is the weld groove angle will change as spatial location changes. That leads to the complex and changeable welding deformation. Under normal circumstances, it is welded by Manual CO2 Welding. But there are some problems: low productivity, poor welding quality, the production environment is poor, thus forming effect of welding is often poor, and so on. To solve these problems, we decide to use robot. So we must solve the problem of Robot Change Groove Welding. This paper is to appear in the actual welding bevel angle of the welding variables, and proposed use of arc welding robot welding groove angle changes. We analyzing the results and find out various process parameters on the changing slope mouth robot welding process and molding analysis the influences of the experimental results, and to play a guiding role in Subsequent experiment . Groove processing on 12 mm thick Q235B to Marine steel plate according to the requirements of the experiment and according to different angles groove divided into eight groups experiment. We choose MAG as the welding way According to the changing slope of the robot welding steel mouth requirements. By changing the current, voltage, welding torch swing and welding speed way parameters we make and optimize the process parameters of Robot Change Groove Welding. In guarantee weld beauty, keep the multilayer multi-channel welding layer of consistent, and ultimately more than basic same high weld. After experiments we found that Robot Change Groove Welding is very sensitive to the change of angle and blunt edge a
