A method of welding high reflectivity materials by laser radiation comprising cladding material in the area to be welded with a low reflectivity material and subsequently directing a coherent beam of laser radiation, pulsed or continuous, onto the clad material to form in the weld area a molten alloy of the two materials which, when cooled, forms a weld nugget which is integrally bonded with the high reflectivity material.
