Presented at ICALEO 2008
Surface modification technologies such as electro-plating, thermal spraying and laser cladding are commonly used to improve functions of low functional materials surfaces. Among them, laser cladding method is a good coating tool for surface modification of materials used in many industrial fields, since they have low heat affection on substrate. Recently, a thin cladding layer is required for alternative of electro-plating, ...$28.00

Welding of aluminium alloys poses many problems like porosities, lost of alloying elements, bead geometry and softening of heat affected zone. Laser welding is widely used in industrial production owing to the advantages such as low heat input, high welding speed, formability and high production rate. Due to these unique advantages, the potential of laser welding ...$28.00

Laser drilling is the very first application found for high power laser. However the phenomena involved in percussion regime to drill sub-millimeter holes are not still understood. This work deals with the study of laser transmission through a hole. This transmission is essential to drill hole in a target with complex geometry for not drill matter behind. This study show the influence of target thickness and laser parameter on the transmissio...$28.00
