Application of Metal Technology Supervision in the Whole

Process of Thermal Power Infrastructure Projects

Wang Xin-wei，Shi Tian-qi

[Abstract]The technical supervision of the entire metal process of thermal power infrastructure projects is the top priority of engineering quality control. It is a complex and huge system project from design， manufacturing， installation， commissioning， and commercial operation. Metal welding will affect the quality of construction. Throughout the entire construction process. While continuously strengthening welding quality control during construction， metal inspection and metal supervision of the entire infrastructure construction process will effectively reduce hidden dangers in construction. During this period， metal welding is the key work during installation. The quality of welding directly affects the safe， economical， high-quality and efficient operation of the equipment. At the same time， the quality of welding also affects the service life of the equipment. How to give full play to the responsibilities of metal technology supervision and control the welding quality throughout the entire process of the infrastructure construction is related to the foundation of the long-term operation of the unit.
