    摘要: An improved process for repair of worn and damaged surfaces of railway structures such as frog and diamond transition surfaces, rail head surfaces and wheels. A worn or damaged surface is prepared using a robotically-controlled laser to melt or gouge away metal using controlled laser energy and air pressure to remove existing worn or damaged surfaces. The process further utilizes laser cladding, laser weld overlaying, or laser additive manufacturing, of formulated powder, wire or stick welding material to worn surfaces that have been prepared for material build-up to original dimensions and similar metallurgical properties.
