| Abstract: |
| Based on Microsoft Visual C++6.0,a system composed of software and hardware was designed to collect,display and backup the welding current and arc voltage in submerged arc welding.Welding current and arc voltage were analyzed using the theory of statistical process control.The results show that,when the welding process is in abnormal,the related information can be drawn by the system in time,which reflects the stability of submerged arc welding process. |
| Key words: statistical process control submerged arc welding control limits standard deviation |
