An integrated methodology for estimating the interface temperature and effects of powder diameters in laser transmission welding process

“…The infrared thermal camera measures temperature by recording the infrared radiation emitted from an object [12]. The camera captures and stores the thermal data as digital images, which are used to calculate the temperature of the object.…”

“…The absorption of transparent thermoplastic restricts the heat radiation from the interface to the surroundings, and the tested surface temperature is lower than the actual temperature in the joint [10]. As published by Goyal et al [12], the temperature tested directly by the thermal imaging camera is below 85°C, the melting of thermoplastics cannot occur at this time. A similar phenomenon existed according to Mayboudi et al [13].…”

“…Recently, the metal powder is selected as a novel and eco-friendly laser-absorbent to carry out LTW of thermoplastics [12,16,17]. The change in metal powder diameter affects the multiple reflections during laser-material interaction and further determines the temperature level which is essential for good welding.…”
