TWI Industrial Member Report Summary 520/1995

Scope
Welded specimens incorporating transverse butt joints in 12.5mm thickness C-Mn steel were produced by electron beam welding in the 75kW EB2 facility at TWI. Fatigue tests were performed to determine the fatigue strength of EB butt welds in seven different conditions: as-welded (with or without backing bars); welds (without backing bars) having received a second smoothing pass; welds with backing bars with the bar removed and the root side ground flush; welds (with or without backing bars) having received uncontrolled flush grinding on both sides; and welds without backing bars having received full grinding on both sides.
The results are likely to be of interest to designers of engineering components to be fabricated using EB welding and which will be expected to experience cyclic loading conditions in service.
