With modern industrial production requirements, and other various fields, welding technology progress. The quality of the welding technology determines the anti hull construction quality. So, the research and development of automation, mechanization, high efficient welding technology becomes the shipbuilding enterprises improve the quality of shipbuilding and manufacturing rate, reduce the production cost. Welding technology in the industrial applications of short history, but its development is very rapid. In just a few ten years, welding has been widely used in metal structure in many industrial departments. This article can be divided into the introduction to ship under construction in the process of welding technology and quality inspection and control two parts. Through to the commonly used welding method，Introduction, understand common operation process of the welding process and the problems need attention, and the implementation of the welding process, welding structure defects were analyzed, and the processing method of the
