1、质量管理前状况在水箱制造的全过程中,其总成装配的六道焊接工序(即芯子焊接、头子焊接、进出水管焊接、上水室焊接、下水室焊接、加水口、回水管焊接等)质量的好坏是直接影响水箱漏水的主要原因。开展全面质量管理工作以前,就因为补漏率很高,有时竟高达80％,既浪费人力、物力,又直接影响产品使用性能。能不能降低补漏率呢?QC小组认为:只有提高上述六道焊接工序的加工质量,才能降
1, quality management before the situation in the tank manufacturing process, the assembly assembly of the six welding process (ie core welding, welding head, access to water pipe welding, water room welding, water room welding, water inlet, return pipe welding Etc.) quality is a direct impact on the main reason for water tank leakage. Before conducting total quality management, it was because of the high rate of back-leak, sometimes up to 80%, which wastes human and material resources and directly affects the performance of products. Can not reduce the trap rate? QC team believes that: only to improve the processing quality of the above six welding process, to reduce
