I thought it was a well recognized fact that monatomic Hydrogen only combines to molecular Hydrogen in three body collisions? (I.e. not through emission of a photon). That's why the Langmuir atomic Hydrogen torch works. If recombination by emission of a photon were possible, then the atomic Hydrogen formed in the arc would recombine long before it reached the work piece, and the whole concept would be useless (i.e. one might just as well use an arc welder).
