The Influence of Nanosecond Fibre Laser on the Removal of Paint on Metallic Surface

Abstract

This research aims to study the effect of nanosecond laser parameters on the paint removal process and obtain a set of parameters that would result in the highest paint removal efficiency. In this study, the effect of laser paint removal parameters such as power, defocus distance, and the number of loops are studied with an optical microscope to observe surface features. The laser paint removal process is conducted using the IPG YLM 200/30 -Q pulsed fiber laser machine. The process sample was examined with an optical microscope to analyze the effectiveness of this laser paint removal process. The results indicated that the power and number of loops significantly enhance the paint removal process. The selection of correct frequency, power, hatching distance, scanning speed, and defocus distance also play a significant part in the efficiency of the laser paint removal process.

A review on the formation of colors on SS304 stainless steel induced by laser color marking technique

“…Amongst these manufacturing processes, laserinduced color marking of metals is gaining recognition and is increasingly applied in various industries in the new era of technological development. This process is rapidly replacing traditional marking methods such as painting, etching, and printing [8,9]. However, the process adds color to an object that is being marked merely "stains" on the surface.…”
