In this study, many operations carried out by
traversing laser beam on 6 mm thick S960 steel plates for various
laser welding speeds and powers in order to determine influence
of welding speed and power on penetration, shape of fusion zone
and heat affected zone. A 16 kW Ytterbium fibre laser and pure
argon as shielding gas were used in this experimental study. Data
was evaluated and compared with some previous studies.
Furthermore, an empirical formula between heat input and weld
bead width was developed from results.

In this work, thermal cycles were applied to samples of CuAl10Fe aluminum bronze alloy which are commonly used in marine hardware, shipping and journal bearings. The samples were maintained in heat treatment furnace at 950 oC (for 30 minutes) and cooled after than subjected to aging process by storing in heat treatment furnace (at 100 oC and 150 oC) for different times (8, 10 and 12 hours). Therefore, aged samples of the data on microhardness and wear resistance values were compared to non-aged base sample depending on the microstructural transformation. As a consequence of this, there is an important increasing at aged samples of microhardness and wear resistance values when comparing with non-aged base sample.
