.... The FCAW procedure was completed with a wire feed system using AWS E-70G grade commercial wire. It was intimated that the wire had been appropriately stored prior to use. This I-beam formed the lower chord of a large structural steel truss. The weldment between the two beam sections was completed...

... of the snubbers will give rise to increased vibration of the blades and the onset of impact fretting. In some turbines, a wire is threaded through holes in the outer ends of the blades to dampen down vibration. In this case, the frictional energy dissipated in the fretting process is the effective agent and may...
