“…Finally, a combination of TGM and UM is known as the coupling mechanism (CM). [12][13][14] Till now, laser bending technique has been used only to form sheet metals, but in the present study a diode laser was successfully used to bend commercial AFS panels. This study extends the application of laser sources in the metal foam field; in fact, they have been used so far only for welding [15] or assisted foaming.…”

Aluminum foam sandwich panels were laser bent by means of a diode laser. Two panels different in thickness were used in bending tests; the effect of the main process parameters (laser power and scan velocity) on the bending efficiency was investigated as well as the contribution of the panel skin, and the protective gas. As a result, a very good formability was observed for the laser processed panels.

“…Nas soldas feitas por condução, ou seja, com menores intensidades do feixe laser, existe claramente um efeito de deformação permanente das chapas. O fenômeno envolvido é chamado de Mecanismo de Gradiente Térmico, ou TGM da sigla em inglês de Thermal Gradient Mechanism [2]. O mecanismo é apresentado esquematicamente na Figura 1.…”

“…In particular, LBF employed for the production of sheet metal prototypes, alignment and adjustment procedures, as well as for the bending of prototypes [6,7] as it is nearly free of spring back [8,9]. The LBF process has been investigated in applications involving different materials such as mild steel [6,7,10,11], stainless steels [12,13], aluminium and its alloys [7,14] titanium and its alloys [6,15], and fibre metal laminates [16].…”

Abstract. The laser beam forming (LBF) process is a unique manufacturing process that has the potential to revolutionise rapid prototyping in the automotive and the aerospace industries. Traditionally, these industries require expensive tooling (stamping dies and presses) to form parts from sheet metal to develop prototypes for testing and evaluation. However, LBF offers an affordable non-contact and flexible rapid prototyping method for most of the manufacturing the industries. Despite these unique benefits, it is important to investigate the evolved microstructure because LBF employs high laser density to induce thermal stresses in the material to create the desired deformation. The study examines the microstructural development during laser beam processing of Ti-6Al-4V alloy sheets. The Ti-6Al-4V sheets were successfully processed at two different parameters of 800 W and 1000 W, and further microstructurally characterised through the optical microscopy. The results show that the micrograph of the parent material consists of a mixture of equiaxed and acicular alpha and beta-phases which are typical of Ti-6Al-4V. The micrograph of the sample formed at 800 W shows structures of globular particles of beta-phase in the alpha-phase matrix with an average grain size of about 12 µm. Also, there was a presence of bands of martensitic structure on the micrograph as a result of the heating from the laser beam. Similarly, the samples processed at 1000 W shown in the micrograph an alpha -phase and apha+beta-phase with an average grain size of about 8 µm with traces of martensites.
