Analysis and Preventive Measures of Common Quality Problems in Installation and Welding of 9%Ni Steel Wall Plate
The welding of 9%Ni steel is one of the key construction contents in LNG engineering project.Taking a LNG engineering project as an example,this paper analyzes the quality problems in the installation and welding of the inner tank wall plate of LNG project,and develop preventive measures.In view of the verticality,group gap,damage of base metal,non-fusion,crack and Gas Hole,etc,which are produced in the course of the installation and welding of the wall plate,this paper analyzes them one by one,formulates the countermeasures,and deals with the defects,at the same time,preventive measures,to a certain extent,reduce the production of quality defects.
