Welding tasks in shipbuilding create great problems for a manual welder since welding takes place in closed area with associated work environmental problems. This paper addresses the problems involved in the welding robot with control algorithm and system. The control system may similarly be modified as a tracking simulation test. The performance of the control system is assessed through the use of field data. The aim of this paper is to determine feasible parameters for a welding procedure with simulation for seam tracking of welding robot system. The main advantage of tracking simulation is its flexibility in that as the welding parameters are modified at a sufficiently high rate. Tracking simulation showed that the development of robot control algorithms should be performed by simulation, since it saves time, expenses and efforts. This paper will contribute to an increased use of automated welding technology with tracking simulation methods. Also, this paper’s results can be used for the optimization of welding process using simulation method with LabVIEW.
