1. Experimental Development of Dual Phase Steel Laser-arc Hybrid Welding and its Comparison to Laser and Gas Metal Arc Welding
Abstract Dual phase DP600 steels have been used in many automobile structures and laser welding has been the standard method for the joining of different sections. This work proposed a comparison between laser welding with arc welding (GMAW) and with hybrid laser-arc welding in order to access the microstructures and the mechanical behavior. The laser and hy

2. Effects of the heat input in the mechanical integrity of the welding joints welded by GMAW and LBW process in Transformation Induced Plasticity steel (TRIP) used in the automotive industry
Neste trabalho, uma chapa de aço de alta resistência (AHSS - Advanced High Strength Steel) tipo TRIP (Transformation Induced Plasticity) empregado atualmente no setor automotivo foi soldado usando o processo de soldagem a arco com arame solido sob proteção gasosa (GMAW) e soldagem com LASER de CO2 (LBW). As propriedades mecânicas das amostras soldadas q

3. Avaliação de Processos GMAW Duplo-Arame em Baixa Corrente com Controle do Formato de Onda e com Auxílio de Feixe de Laser / Assessment of Low Current Tandem GMAW Processes with Waveform Control and with Aid of Laser Beam
In face of manufacturing-related limitations in the present-day industry, the welding sector has looked for new, or even not so new, processes. In other words, it has invested in the development of new processes and, especially, in the use of new arrangements for conventional processes. Thus, the aim of this work was to assess the use of combined processes a

4. Recent developments in high productivity pipeline welding
Installation of new pipelines is predicted to grow at a rapid rate over the next twenty years, due in part to the increase use worldwide of combined cycle power generation plant using natural gas a fuel. The need to construct large diameter pipelines over long distances has led to an increased demand to improve the productivity of pipeline girth welding. Man

5. Metal transfer in the aluminum gas metal arc welding
Among the aluminum welding processes, the GMAW (Gas Metal Arc Welding) process can be easily made automatic, has high productivity and great versatility regarding the type and thickness of material used in welding. The possibility of changing the transfer mode to adapt to different thickness, joint types, among other aspects, is another important and attract
