Cutting Properties of Austenitic Stainless Steel by Using

  • AbstractIntroductionExperimental ProcedureExperimental Results and DiscussionsConclusionsRecently, laser cutting is used in many industries. Generally, in laser cutting of metallic materials, suitable assist gas and its nozzle are needed to remove the molten metal. However, because of the gas nozzle should be set closer to the surface of a workpiece, existence of the nozzle seems to prevent laser cutting from being used flexible. Therefore, the new cutting process, Assist Gas Free laser cutting or AGF laser cutting, has been developed. In this process, the pressure at the bottom side of a workpiecComposition Change of Stainless Steels during Keyhole also affected by welding parameters WELDING RESEARCH 258-s WELDING JOURNAL / JULY 2017, VOL. 96 Composition Change of Stainless Steels during Keyhole Mode Laser Welding The experimental and theoretical study of composition changed during keyhole mode welding of stainless steels T. LIU, L. J. YANG, H. L. WEI, W. C. QIU, AND T. DEBROY ABSTRACT Experimental investigation of hydrodynamics of melt experimental results. 1. Introduction Since its invention in the 1960s, laser cutting of steel has been widely used in industries owing to its advantage of processing speed or capability of automation. Along with applications, a number of research works have been conducted to understand the fundamental mechanism of the process. Now there exist

    Experimental study of laser-oxygen cutting of low-carbon

    Oct 31, 2014 · Abstract. The results of an experimental study of laser-oxygen cutting of low-carbon steel using fibre and CO{sub 2} lasers are generalised. The dependence of roughness of the cut surface on the cutting parameters is investigated, and the conditions under which the surface roughness is minimal are formulated. Figure 1 from Investigating the CO2 laser cutting Abstract Laser cutting of medium density fibreboard (MDF) is a complicated process and the selection of the process parameters combinations is essential to get the highest quality cut section. This paper presents a means for selecting the process parameters for laser cutting of MDF based on the design of experiments (DOE) approach.
