Research and development of large angle SAW technology for LNG storage tank
Due to the special welding position of large fillet of LNG storage tanks,all large fillet welds of LNG storage tanks under construction in China are carried out by shielded metal arc welding welding(SMAW)process,this welding method has long welding cycle,takes up much manpower and equipment resources,and every weld needs to be polished after welding,and its appearance is poor,it has great influence on the control of time limit and cost in the construction process.
