API 650 Tank Joint Welding Inspection for Field Erected

Sep 09,2014 API 620 tanks single welded lap joint#0183;Submerged Arc Welding (SAW) became popular in the tank industry in the early 1980s.This process was used on lap welded bottoms and roofs and butt welded shell joints.The first use of this process took many years of education to develop a method of welding that would be clean of porosity under the surface of the weld.API 650 Joint efficency - API (American Petroleum API 620 approach differs from API 650 which allows fillet-welded shells with penalty in allowable stress (joint efficiency E=0.7 for Double full-fillet lap joint ).As far as i understand,single fillet welds are allowed at API 650 for the roof and bottom plates lap joints of atmospheric tanks because they are not subject to high membrane stresses.API 620 Design and Construction of Large Welded Low Except for all lap-welded roof seams and flange-to-neck joints,this identifying mark shall be stamped,either by hand or machine,on all tanks adjacent to and at intervals of not more than 3 ft along the welds made by a welder or welding operator; altematively,the manufactmer may keep a record of welders employed on each joint and shell
