Historical steel production

This old video from the early 1970's shows a number of metal arc sprayed coatings that were applied wit Metallisation systems in steel mills and foundries. These applications are still relevant and applied today. HVOF and laser cladding coatings have joined the arsenal of coatings used to combat the harsh environments of the steel mill. The film is showing its age but demonstrates that the metal spraying process is not at all new and has a long and proven history. Of particular interest is mention of the thick steel coatings (up to 50mm or 2") applied in some applications.
