The surface of a product is profoundly related to its properties and function such as abrasion, corrosion, and scratch resistance which make surface structuring a crucial factor in industries. Laser remelting can be used to generate complex surface structures such as sinusoidal, rotational symmetric wave and helical structures. Moreover, it does not require any surface finishing operation as compared to conventional methods. Surface structuring due to laser remelting is a result of self-organization of molten material under the influence of surface tension and thermal flux driven Marangoni flow, control of which is essential for generating different types of surface structures. To understand its underlying principal and melt pool dynamics, a numerical model is developed which takes into account the processing parameters such as spatial power modulation, scanning speed and peak laser intensity. It has been found out that spatial power modulation and scanning speed affect the surface structure geometry profoundly. The experimental results validate the phenomenon in numerical simulation.
