Abstract: The purpose of this study is to design and construct welding machine calibration system including welding skill development system. Calibrated welding machine and qualified welder ensure the quality of weld in order to reduce loss and to support industry entered standard system as well.To contruct welding machine calibration system , the researcher used welding machine calibrator to determine efficiency and characteristic of welding machine under test. To develop welder’s skill according to national standard, the calibration welding machine calibrator is used to measure parameter values: current , voltage , and speed of welding by electronic circuit and microcontroller while the welder is working. The parameter values will be sent and recorded into a computer through RS 232 port. Data from computer are used to process as visual guide and assessment record for welder skill improvement. The evaluations of welding calibration system are done by calibration on MIG welding machine in motorcycle part manufacturing lines. The calibration results showed that the welding machines are constant voltage type and have efficiency more than 70 percent. The evaluations of welder skill development system are done by measurement system analysis (MSA). The variation of welding calibration system cause by measurement is very few. From welder skill development analysis, more than 70 percent of welders under test can improve their skill closer to standard with 95 percent confidence level.
