What Your Fabricator Wishes You Knew About HSS Steel

A stepped connection is preferred as it leaves a landing on the flat of the chord member to make an economical fillet weld connection.In a matched connection,especially if the tube and/or corner radius are large,welding may require a steel backing or a backing weld to close the root of the joint.Welding In,On and Around Steel JoistsSteel Joist Institute Standard Specifications 44thEdition For flare bevel groove welds,the effective weld area is based on a weld throat width,T,where T (inches) = 0.12 D + 0.11 Where D = web diameter,inches or,T (mm) = 0.12 D +2.8 Where D + web diameter,mm.76.AWS D1.1:2015 Structural Welding Code--Steel.Welding Considerations for Designers and Fabricatorsment connections,or tube columns to supporting beams.These are relatively easily designed and fabricated connections,although the limit states that must be considered in the design of such connections are somewhat different.A popular application of HSS is for trusses,or truss-like assemblies,where tube-to-tube connections are made.

Assumption of steel connection being rigid or pin

1.If your beam is designed to be simply supported and the end connections are welded all-around,then those connections will need to appreciably deform/fail in order to re-distribute moments to the midspan.2.Transversely loaded welds are extremely stiff and brittle,so in order for number 1 to occur it would take a great amount of end rotation.AD 411 Design of web to flange welds in plate girdersdetermined size of fillet weld which is larger than the calculated value.Contact Richard Henderson Tel 01344 636555 Email [email protected] 1.BS EN 1993-1-5:2006 Eurocode 3 Design of steel structures Part 1-5 design of plated elements AD 411 Design of web to flange welds in plate girders equation 1 equation 2 equation 37.Welding - Australian Steel Instituteweld size below which a fillet weld is the cheaper solution lies generally in the range 12-16 mm for many applications.Further information on the relative cost of fillet and butt welds can be found in Section 10 of Ref.7.3.WELD COST ($/m) WELD SIZE (mm) FILLET WELD BUTT WELD 12 16 FIGURE 7.3 Weld cost graph 7.3 Welding Processes
