tank roof welds - American Welding Society

Jan 15,2007 api 650 tank welded joint#0183;API 650 Section 3.10.2.5 (Note the word shall).The roof is designed to fail vs.the shell failing.ie-the roof blows off vs.the tank blows out.Was the tank constructed based on API 650 Appendix F? Even that does not allow backewlding the roof plates to the compression bar or top angle.See API 650 Appendix F.3,Figure F-2.What you mean by peaking and banding? - BaytThe peaking is the adjustment and checking for the roundness and the curvature of the shell plates around the vertical joints and its done befor and after welding process,and about the banding is the adjustment and checking the straightness and verticality for the shell plates around horizontal joint (between shell courses) and as the same its done befor and after welding .What is the Joint Efficiency? - Arveng Training EngineeringJoint efficiency of welds can be defined as the reliability that can be obtained from the joints after welding.This coefficient can adopt values smaller than 1,and to some extent it can be said that the joint efficiency is a way of reducing the allowable stress of the material.Therefore,the joint
