As special pressure equipment, boiler and pressure vessels once quality problems are likely to cause serious safety accidents, to the national peoples lives and property brings a great threat, welding plays a very important role in the safe operation and service life of boiler and pressure vessels, and to some extent, boiler and pressure vessel quality essentially refers to the quality of welding, Welding materials, welder management, welding inspection, welding process and welding equipment are the main influencing factors in the welding construction process of passing pressure vessel. Therefore, in the welding construction process of boiler and pressure vessel, it is necessary to effectively control the above factors that may affect the welding quality, so as to effectively improve the overall welding quality of pressure vessel and ensure that pressure vessel products meet the relevant national standards. This paper mainly discusses the welding quality control measures of boiler pressure vessel.
