The laser beam GMA hybrid process has, already since the beginning of the year 2000, been used for applications in shipbuilding. At that, linear welds have been welded as butt welds and also as fillet welds as a solid weld connection in the flat position (PA). It is, therefore, the logical consequence, to extend this spectrum to other welding positions, particularly due to the easy handling of the we...$28.00

If the powder bed laser melting process is now widely used, the fusion process is not clearly understood yet. Particularly, it is important, formation of spatters and melt pool stability has not been analysed. From previous works, thermo convective effects have evidenced but should be more inv...$28.00

Presented at ICALEO 2013
In selective laser melting, products are generated by selectively melting powder layer by layer. The amount of energy coupled into the powder results in a melt pool that can be observed by detecting its thermal emission.
A sensor system acquires information during processing through a scanner based manufacturing system for selective laser melting. The coaxially coupled detection system is compris...$28.00
