Adjustments to a pipeline’s cathodic-protection program can help address possible hydrogen diffusion brought about by nonconformance with welding procedure specifications (WPS) during ...

Hydrogen’s thermal conductivity is also why it is used in some welding gases, with certain studies claiming that it improves weld quality on even lower quality steel.

·The Hydrogen diffusion rate to the surface will be the rate controlling reaction step if the H-ion concentration is low. J = - D 0 exp{-E/kT}(dc/dx) From: M.G. Fontana, "Corrosion Engineering," Wiley ...
