The search for a industrial method of production more systematic, with better quality control and increased productivity have driven the use of robots in various industrial sectors. And the welding, as an industrial and ...

High-strength, low-alloy (HSLA) steels are widely used in the automotive and oil industries due to their good mechanical properties and weldability. The selection of the welding process depends on several factors, including ...

This paper reports an experimental study of laser welding on duplex stainless steel UNS S32205 employed in the oil and natural gas industries. A pulsed Nd:YAG laser was used to weld the specimens. Bead on plate condition ...

Fatigue crack usually initiates at welded joints of structural elements. For a high-responsibility aeronautic component, called Motor-Cradle - critical to the flight safety -, successive weld repairs are carried out toward ...
