The impact of zinc-coating on laser hybrid welding of steel
ICALEO 2007: 26th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2007Hybrid Nd:YAG/MAG welding of ultra high strength steel is studied for 1.5 mm thick sheets in I-, T-and overlap joint type configuration. Untreated and zinc-coated steels were compared, causing distinct differences in terms of process stability and welding result.

The impact of fiber laser welding parameters on alloy 6061-T6
AIP Conference ProceedingsIn the aircraft industry, which has a large number of connections of various designs previously made by riveting, aluminum alloys are frequently used. Mounting defects include the additional weight of the structure, stress concentration, crevice corrosion, and vibration-induced collapse. In addition, it is a labor and time-intensive job.

Review of Experimental and Computational Investigations into Laser Impact Welding
Journal of Manufacturing Science and EngineeringAbstract Laser Impact Welding (LIW) is a specialized, solid-state method for joining small metallic sheets or foils at the scale of a few millimeters using high-powered laser pulses. Unlike traditional welding methods, LIW avoids bulk melting, thereby minimizing the occurrence of associated defects and distortions.

Impact of temperature sensor location on the quality of control in laser welding
SPIE Proceedings, 2003In the case of the laser welding control by means of the infrared thermographs, the information concerning the quality of the weld is obtained by using a temperature-measuring sensor at a specific point on the welding surface. In order to obtain good efficiency of the laser welding control, the point of the temperature measurement has to be chosen ...

The Impact of the Laser Welding Speed on the Mechanical Properties of Joints in Multilayer Pipes
Materials Science Forum, 2012The paper assessed the impact of the laser welding speed on the strength and fatigue properties of the aluminum layer found in multilayer pipes. The conducted experiment has shown that during the adjustment of the welding speed one has to take into account not only the results of static tests, but also the results of fatigue tests.
