WebThe strength loss due to welding process poses a high risk of catastrophic rolling contact fatigue failure in the heat affected zones of flash-butt rail welds. Accurate characterisation of fatigue crack growth behaviour in such regions can provide a database for customising safer and more efficient maintenance strategies. WebJun 16, 2008 · The flash welding process is similar to the ERW process in that it is a non-fusion welding process, but the thicknesses for flash welding are generally higher and ERW is generally a continuous process while Flash Welding is a per-piece process. In contrast, as far as I know, silicon content is not restricted for friction welding.
