Functional gradient materials (FGM), with their composition gradually varied in different positions, have attracted much attention for research and development during the years. Normally there are two types of functional gradient materials: one without the formation of intermetallics which is ...$28.00

Presented at ICALEO 2009
The use of porous engineered materials is gaining popularity in biomedical implant manufacture due to its capability to promote increased osseointegration and cell proliferation. A method to produce such parts is laser direct metal deposition (LDMD) - a rapid manufacturing technique that has much flexibility. In this work, a 1.5 kW high power diod...$28.00

Presented at ICALEO 2009
With the increased interest in Hybrid Laser Arc Welding (HLAW) in the U.S., the process is being certified for use on increasingly higher strength steels. The addition of the laser to the traditional Gas Metal Arc Welding (GMAW) process results in a higher total melt volume than that of the GMAW process alone. Studies of hydrogen content of HLAW welds were carried out in which comparisons w...$28.00

Presented at ICALEO 2009
Laser welding and laser-MAG hybrid welding are used more often in heavy industry. It is very typical that a product earlier welded by arc welding needs changes to its design when laser or laser-MAG hybrid welding processes are considered. This presentation is based on a Masters thesis, the aim of which was to give guidelines for structural designers. The material used in the welding tests was S355K2 (according to EN 10025-2:2004). Joint geometries were butt and T-j...$28.00

Presented at ICALEO 2009
Hybrid laser-arc Welding of galvanized steels in a gap-free lap joint configuration is a complicated welding process, which is involved in many welding parameters such as laser power, welding speed as well as the distance between laser beam and GTAW torch. Furthermore, the dynamic behaviors of the molten pool, which reflect the stability of the welding process, is significantly affected by the dynamic behaviors of highly-pressurized z...$28.00
