During the project construction,plenty of welders work in different area and are managed by different subcontractors,the personnel flow is large,and field welder tracking has always been a weak link in welder management. In this paper,a hand-terminal system is developed,which can easily realize the welder information,certificate information and project ownership information under off-line state,and alarm and intercept the blacklist welder,which can significantly improve the efficiency of the spot welder mana-gement and effectively reduce the quality risk brought by the welder management.
