Fillet welds,or T-joints,are widely used in different construction sectors,storage tanks,naval components,bridges,and more.A failure in a fillet weld may lead to heavy loss or wastage of materials contained by a tank,or it may have other major consequences to the fitness-for-purpose of assets.Images of Unanchored tanks Fillet Weld imagesREVIEW OF CURRENT TRENDS IN DESIGN OF WELDED6 Unanchored tanks F.1 Unanchored tanks K.1 7 No welding or attaching to internal roof supported structure 126.96.36.199 No welding or attaching to internal roof supported structure K.2 8 Material for joint members No strictly proposed or defined,but assumed for joint failure pressure calculation (C-steel steel with yield stress 220 MPa)How to determine joint efficiencies for tank inspection Dec 09,2014 unanchored tanks fillet weld#0183;Joint efficiency varies with weld type.Various weld types and joint efficiencies for them can be found in Table UW-12 Maximum allowable joint efficiencies for arc and gas welded joints of ASME VIII,Div 1,Sec B.That way,a butt welded joint will have a greater value of E than a fillet
