Some properties of laser claddings made with several
commercially available alloy 625 powders were
investigated. Nickel based alloy 625, generally
known also as Inconel 625, is widely used also on
laser claddings due to its good corrosion properties in
various environm...$28.00

Welding requires acceptable quality along the entire weld. In particular, the weld surface geometry has a vital role in ensuring an adequate fatigue life. This paper describes the results of a case study of laser hybrid arc welding of a structural vehicle component of complex geometry. By isolating the various weld geometries, alo...$28.00

In this report we analyze the information content of back reflected laser light during high-power CO2-laser cutting of metal sheets. A fast sensor which is mounted coaxially to the beam path of a CO2-laser cutting machine behind a scraper mirror detects the back reflected laser power from the interaction zone...$28.00
