Publikováno v: International Communications in Heat and Mass Transfer. 92:112-119

The heat flux inverse analysis is significantly affected by the heat flux distribution in laser welding simulation. This work proposed a different approach for the heat distribution which predicts the temperature and the weld bead in laser welding. T

Laser remelting of WC-CoCr surface coated by HVOF: Effect on the tribological properties and energy efficiency

Autor: Milton Pereira, Adriano de Souza Pinto Pereira, Alexandre da Silva Rocha, Elvys Isaías Mercado Curi, Richard de Medeiros Castro, Rafael Gomes Nunes Silva, Luiz Fernando Feltrim Inacio

Publikováno v: Surface and Coatings Technology. 427:127841

In this article, the tribological behavior and energy efficiency of surfaces coated with WC-CoCr/HVOF were evaluated after a laser remelting process, using low and high laser energy densities, respectively, 33.3 and 150 J/mm2. The purpose of laser re

Electric evaluation of hybrid laser-TIG welding: Interaction between arc and laser plume

Autor: Milton Pereira, Rafael Gomes Nunes Silva, Adriano de Souza Pinto Pereira, Mateus Barancelli Schwedersky, Max Baranenko Rodrigues

Publikováno v: Journal of Laser Applications. 32:022035

Hybrid laser-arc welding (HLAW) is regarded as a promising joining process, since it can compensate disadvantages from laser autogenous welding and arc welding by uniting both techniques into a single melt pool. Such a process can achieve relative hi

Parametrization methodology for laser remelting applied over laser metal deposition single tracks

Autor: Adriano de Souza Pinto Pereira, Milton Pereira, Rodolfo Marques Pôrto

Publikováno v: Journal of Laser Applications. 32:022069

Laser metal deposition (LMD) is increasingly becoming an interesting tool in recent years, especially as one capable of repairing complex metal parts or depositing special materials over the surfaces of high-reliability components. Regardless of the

Quality analysis method for powder deposited layers applicable to selective laser sintering and selective laser melting processes

Autor: Milton Pereira, Adriano de Souza Pinto Pereira, Denise Albertazzi Gonçalves, Walter Lindolfo Weingaertner, Wei Lin

Publikováno v: Journal of Laser Applications. 31:022306

Selective laser sintering and selective laser melting (SLS/SLM) are additive manufacturing processes based on a layer-by-layer part construction approach by powder bed stacking. At each layer, the laser beam melts a material on the powder bed to crea
