Welded Joint Efficiency Table Recommendations Engineers

Joint efficiency is concept found in several API and ASME codes.It is a numerical value,which represents a percentage,expressed as the ratio of the strength of a riveted,welded,or brazed joint to the strength of the base material. Single full fillet lap joint with plug welds--0.50.Single full fillet lap joint without plug welds--0.45 Vacuum box test - AST Aboveground Storage Tank ForumJun 09,2012 API 650 tanks Fillet Weld#0183;since you are going to replace the bottom plates,as per API,all the fillet weld seams of the bottom plates are required to be tested by vacuum box.this is for checking any pin holes leak or surface leaks near the weld joints.In addition to the fillet weld if the tank bottom plates,you have to check the shell to bottom weld joints also by Technical Inquiries for API Standard 650,Welded TanksDo the current rules in API 650 allow for a carbon steel tank to incorporate stainless steel components such as Referring to API 650,Section 3.1.5.4,is it required to make a full fillet lap seam weld (top side only) under the tank shell? Yes.3.1.5.8 10th - Nov.1998
