对焊机电流／电压表准确度控制方法的再探讨

On Accuracy Control Method of Current and Voltage Meter in the Welding Machine

文章从焊接设备及其工作原理、焊接工艺、焊接操作技术、企业计量管理等方面，结合企业实际案例整理、数据分析，指出了当前焊机电流／电压表准确度控制的误区，给出了较为现实的科学管理方法。将焊机电流／电压表定性为指示性仪表，并列入C类计量器具管理。

On the basis of the actual case settlement and data analysis of enterprises, and from the aspects of welding equipment, working principle, welding technology, operating technology, management of enterprise measurement and so on, this article indicates the present misunderstanding in controlling the accuracy of welding machine＇s current and voltage meter and supplies comparably realistic ＆ scientific management method. The current and voltage meter is considered as indictive instrument, and is classified as C class measurement instruments for management.
