This article will explore the various parameters involved in laser cutting and examine their impact on formability when applied to complex phase steel.

Parameters & Effects on Formability

Power Density

The power density of the laser beam plays a pivotal role in the efficiency and quality of laser cutting. Higher power densities allow for faster material removal, but excessive power can lead to undesirable thermal effects.

Cutting Speed

The cutting speed determines the rate at which the laser beam travels along the material. It’s a crucial parameter influencing both productivity and cut quality.

Focus Position

Proper focus positioning ensures the laser beam’s maximum intensity intersects with the material’s surface, resulting in optimal cutting performance. This parameter demands careful calibration.

Assist Gas Selection

Assist gases, such as oxygen, nitrogen, and argon, aid in material removal by blowing away molten material. The choice of assist gas significantly impacts cut quality and edge finish.

Complex Phase Steel Properties

Complex phase steel is a type of alloy steel that exhibits exceptional strength and hardness. Its combination of properties makes it an ideal material for components that need to withstand extreme temperatures, pressure or wear. When fabricated using laser cutting technology, complex phase steel can be transformed into components with superior formability and performance.

Test Methods & Results

Test Methods & Results: The research team conducted a series of experiments to assess the effect of laser cutting parameters on the formability of complex phase steel. A total of ten samples were analyzed, each with different thicknesses and varied laser cutting parameters such as beam diameter, speed, frequency and power. To measure the formability of each sample, a tensile test was performed in accordance with ASTM standard E8/E8M-15a. Results showed that increasing beam diameter or decreasing speed had a positive effect on formability for all samples tested. Furthermore, an increase in frequency or power output also increased the formability for some samples but decreased it for others. These results suggest that selecting an optimal combination of laser cutting parameters is essential to producing a metal part with optimum formability characteristics.
