· Beams and columns are usually connected on site by bolting In the case of an RHS beam connection to an Isection column, a welded extended endplate to the RHS beam permits the use of a conventional bolted connection to the column flange or web (see Figure 633)However, welded connections are more flexible The holes used to bolt or pin pieces together during welding are usually drilled in the fabrication shop Beams are not usually welded directly to columns The procedure produces a rigid connection and results in severe bending that stresses the beam, which must be resisted by both the beam and the• Structural welding is a process whereby the parts to be connected are heated and fused with a molten filler metal • Upon cooling, the structural steel (parent metal) and weld or filler metal will act as one continuous part The filler metal is deposited from a special electrode A

However, in beam structures welding is not so common (still I once did a project for a roof where literally all connections were welded) When it comes to stiffness I would say that prestressed connection that is reasonably designed is as rigid as welding (or at least reasonably close to it)0929 · Welded Splice Details For Steel Beams Posted on September 29, by Sandra Typical steel connections axial restraint in steel beams beam to column connection with end splicing i beams structural esdep lecture note wg11 Splicing I BeamsBeam to beam (same section) welded moment connection (one horizontal and the other inclined, ascending or descending) Beam to beam welded simple connection Beam to two beam welded simple connection Splice connection of continuous equal sections with plate Tie detail Baseplate on pad footings, pile caps and mat foundations

72 ADVANTAGES OF WELDED CONNECTIONS The gross sectional area of the welded members is effective since the welding process does not involve drilling holes Welded structures are comparatively lighter than corresponding riveted structures A welded joint has a greater strength sometimes equal to the strength of the parent metal itself · Welded Connections Welded connections have the primary advantage of being simple in design, requiring fewer parts and material Welds however shrink, and this effect needs to be considered in the design particularly for large welds In addition, the inspection of welds is more difficult and hence costlier and more difficult to maintainSpacer – beam When projects are struggling for height, for instance in basements and lofts, it is often preferable to replace a deep beam with two smaller beams However, to ensure stability and resistance to buckling, these beams need to be bolted together, and this is where a spacer is used, and is usually welded to one of the beams
