Welding technology of submerged arc welding materials for marine high strength steel
Submerged arc welding(SAW) is a very efficient method widely used in the welding of marine high strength steel. In view of the base metal characteristic and the requirements of construction project,AWS D1.1-2015 "American Welding Society" is taken as the acceptance standard. The four kinds of SAW materials are used in the SAW procedure qualification tests of 32 mm thickness D36 steel plate. The weldability and mechanical properties of welded joints are studied by nondestructive test of appearance,tensile,bending,impact,hardness and macroscopic metallography detection. The results show that welded joints with good mechanical properties can be obtained by using a suitable welding technology with the four kinds of welding materials. And these welding materials can be applied to the SAW of marine high strength steels.
