... densities that are of the order of 1000 W/cm 2 , such as oxyacetylene flames or electroslag welding, require interaction times of 25 s with steel, whereas laser and electron beams, at 1 MW/cm 2 , need interaction times on the order of only 25 μs. Welders often begin their training with the oxyacetylene...
