The Effect of Laser Beam Welding Parameters onto the Evolving Joints Geometry

Abstract

In our research the effect of a new type of laser beam parameters during the laser welding have been investigated with 80 different welding parameters. The laser welding parameters such as the laser power, laser beam spot size on the surface and feed rate greatly affect the resulting weld geometry. S235 grade steel has been used. The operating equipment was a Trumpf 4001 4 kW disk laser with a diameter of 100 microns optical fiber. The effect of different welding parameters were evaluated from the metallographic cross-section of the welded joints. This article describes the effect of the different laser beam focusing and the welding feed rate.

Investigation of nickel coated steel tapes welded joints

“…One of these materials used as conductive plates is nickel-plated steel plates. Our investigations explore the weldability of this material using a low power 300 W diode laser beam source [1][2][3][4][5][6][7].…”
