Presented at PICALO 2006
Laser Metal Deposition (LMD) is a validated process for repairing aero engine parts and complete components. An increase of the specific efficiency of aero engines is achieved by replacement of heavy parts out of Nickel Base Alloys in the HPC (High Pressure Compressor) and LPT (Low Pressure Turbine) sectors by lightweight parts out of TiAl Alloys in operating temperature ranges from 450 up to 700 °C. Due to the use of these upcoming new materials and n...$28.00

The Influence of High Power Diode Laser in Hybrid Laser-Controlled Dip Transfer GMA Welding
Authors:
Justino Mulima, University of Wollongong; Wollongong Australia
Presented at PICALO 2006
This paper describes an initial investigation of hybrid laser welding in conjunction with enhanced control short-circuiting techniques in Gas Metal Arc Welding (GMAW). A high power diode laser has been used together with controlled dip transfer, to improve deposition rate while achieving deep penetration, high welding speed and high quality butt welds in thin plain carbon steel sheet. The effect of the laser energy on the inherent control of the GMAW system is discussed and the results are compared with conv...$28.00

Presented at PICALO 2006
This paper presents the results of an experimental and theoretical analysis of the effect of joint gap on the strength of hybrid laser-MIG welds. The welds were of the non-full penetration butt type with various joint gaps but identical weld penetration. Impact testing established that a zero gap gave a weak weld because the weld geometry contained the equivalent of a sharp crack ...$28.00
