Pipeline emergency maintenance construction has the characteristics of tight time,heavy task,often affected by sudden factors,and very difficult construction operation. The welding operation is the most important link in pipeline emergency maintenance construction. Whether the quality monitoring is scientific or not is one of the key procedures to ensure the welding quality in pipeline emergency maintenance construction. If the monitoring is inadequate,it will increase the consumption of manpower and cost for repairing the welded joints,even will directly affect the safe operation of pipelines and cause accidents. Combining with the shortcomings of the current welding quality monitoring mode commonly used in emergency maintenance construction,it is analyzed the specific significance of employing welding inspectors as quality monitoring personnel in emergency maintenance construction operation to monitor the welding quality. It is proposed that welding inspectors should take on some new responsibilities under the special environment of emergency maintenance construction,so as to promote the effective improvement of the overall quality management level of emergency maintenance construction.
