Arc Welding Working Hours Based on MODAPTS

MODAPTS of Industrial Engineering (IE) work measurement was used for formulating welding hours. It was analyzed the program, operations and motion of production process on the arc welding production site. According to the theory of similar manufacturing principle, the auxiliary operation of the arc welding was divided into standard operation, typical operation and special operation. Their working hours were respectively analyzed and estimated. Arc welding operation time was treated as a set of the basic time and auxiliary operation sequence time. It is more scientific, rationalization and standardization for the welding hours, and improves the efficiency of formulating welding hours. A using example was given.
