Influência do comportamento dinâmico em juntas do tipo "k" em estruturas reticuladas planas
(2015-10-26)
This thesis presents the study of plane frame structures, also called trusses. The great demand of construction, and projects increasingly bold motivated this research. Three models lattices were performed in order to ...
Análise de deformações e empenamentos em peças de aço carbono para cilindros hidráulicos
(2019-12-17)
Changes in the concept of tractor manufacturing led to changes in cylinder production processes and increased complexity of welding processes, leading to increased distortion and warping. Distortions and / or bends in ...
Influência da resistência dos metais de adição AWS A5.18: ER70S-6 e AWS A5.28: ER110S-G nas propriedades mecânicas aplicado em estruturas soldadas de prensas hidráulicas
(2019-07-19)
Frequently the structures of industrial machines, in this case, hydraulic presses, are manufactured with steel sheets with low carbon content and are joined through welding processes. These processes generate high heat, ...
Estudo de uniões soldadas de chapas de aço SAE 1008 por processo GMAW
(2020-12-25)
Low carbon steel sheets are widely used in the road implements market since the replacement to new projects and applications. The most common joining process for them is the GMAW process because it is easy to automate and ...
Análise de distorções em componentes estruturais de uma carroceria de ônibus causadas pelo processo de solda
(2021-07-20)
The present study analyses the distortion caused in a bus body by the welding process. Distortions in welded parts change the dimensional which has negative consequences on the assembly line when it exceeds tolerances ...
Análise dos parâmetros do processo de soldagem a ponto por resistência na qualidade das juntas em estruturas automotivas
(2021-12-11)
Most of the car bodies are made up of a set of shaped steel sheets, which are later joined through the process of spot welding by resistance. This study aimed to analyze the influence of applied welding parameters, mechanical ...
Efeito da energia de soldagem sobre a zona termicamente afetada de um aço avançado de alta resistência mecânica
(2022-12-19)
Advanced High Strength Steels (AHSS) are an attractive alternative in structural applications. Due to the low content of carbon and alloying elements, AHSS steels have good levels of toughness and mechanical strength, in ...
Desenvolvimento e análise de soldagem robotizada híbrida laser-arco elétrico em reservatórios de ar
(2023-12-12)
The present work seeks to analyze the viability of the hybrid laser-electric arc welding process in air reservoir, replacing the current GMAW electric arc welding process. The tests will be carried out in a robotic cell ...
