| Abstract | The study aims to develop the quality improvement in electronic welding process as a SR Type reducing the amount of waste. By using pareto diagram, It was investigated that the main problem is incomplete welding on the side. Therefore, it was analyzed to find factor that causes incomplete welding on the side using cause and effect diagram, which showed that flux D application factor and flux E application factor resulted in incomplete welding on the side. The design of experiment was applied to determine appropriate quantity of these factors. The result showed that flux D application factor and flux E application factor in appropriate quantity (3 to 5 milligrams) will give the best welding quality according to standard. The determination of proposed operating model using the principle of motion and time study showed that the number of pieces with incomplete welding on the side from the proposed operating model decreased by 93.28 percents compared with the current operating method. |
