Abstract

Laser marking is the process to mark an image by utilizing laser thermal energy used primarily for product identifications and traceability. It is versatile and well known process employed by the manufacturers to mark various materials. The mark produced by a fibre laser beam produces one of the fine marking components and it is well accepted form of marking used nowadays. The research paper revealed that laser beam marking quality is the function of various input controlling factors like laser spot size, transverse feed, scan rate, laser power which had a significant impact on quality attributes. The paper focuses on the creation of better quality equilateral triangular-shaped laser inscribed image on grade 304 stainless steel surface in a shortest possible time. The process variables involved in the present study includes pulse rate, duty cycle, laser power, and scan rate which were varied one at a time for obtaining better marking quality characteristics like high mark quality, closer to target mark angle and less deviation of marked area. The observed results revealed that pulse rate of 50 kHz, laser power of 12.5 W, scan rate of 35 mm/s and duty cycle of 99% provides better marking quality. [ABSTRACT FROM AUTHOR]

Abstract

The operation of laser marking occurs due to oxidation on the metallic surface at a high temperature, which finds applications in many organisations due to its cleanness and high handling speed with the negligible human association. The generated marked objects are permanent in nature, generally utilised for product identity. From the perspective of laser marking, the general requirement of laser marking is mark clarity or marking quality with minimal effect on the workpiece surface. The paper deals with producing good-quality laser-marked surface by the utilisation of process parameters such as transverse feed, average laser power and scanning speed, which seem to have a significant effect on the surface of designed materials for the development of laser marking qualities. The diode-pumped pulsed fibre laser was utilised for the purpose of marking on the surface in a single pass within the minimum possible time. Experimental studies revealed that decrease in transverse feed from 8 μm to 2 μm/laser stroke had a projection towards the increase in mark intensity which could be reached up to 0.95 on the application of the lower value of transverse feed, i.e., 2 μm/laser stroke upon using a proper set of process parameters..
