“…Dykhno, Davis [13] and Meng [14] state that TIG-MIG/MAG hybrid welding, relative to conventional processes, can double the performance because it increases the penetration of the weld, offers greater control over the heat-affected zone and increases the speed of welding, which together characterizes increased productivity.…”

Abstract:The main aim of this work was to evaluate the influence and optimize the factors of the TIG-MIG/MAG hybrid welding process on the geometry of the weld bead. An experimental design using the Taguchi methodology (robust design method) was used to conduct the experiments. The experiments were carried out according to an orthogonal matrix with 27 experiments, with three replicates each, totaling 81 test specimens. The factors (MIG/MAG shielding gas type, MIG/MAG voltage, MIG/MAG wire feed, gas flow rate of TIG, electric current intensity of TIG and welding speed) were varied with three levels each. Penetration, heat-affected zone (HAZ), bead width and bead height were the response variables analyzed. The results showed that the penetration was significantly influenced by the MIG/MAG wire feed, MIG/MAG shielding gas type, MIG/MAG voltage and welding speed. The HAZ has been influenced by MIG/MAG voltage, MIG/MAG shielding gas type, welding speed and electric current intensity of TIG. All factors had effects on the width, except the MIG/MAG wire feed. The bead height was significantly influenced by the MIG/MAG wire feed and by the electric current intensity of TIG. Optimizing the process was performed, so that for each output variable, the values of the factors that should be used were indicated, and the optimization was confirmed by welding test specimens.

“…Vários processos de soldagem vêm sendo utilizados para este fim tais como: Processo a laser, (LBW), processos GTAW ou TIG com alimentação automática de arame (frio e quente), processo GMAW (MIG/MAG) e o processo à Plasma por Arco Transferido (PTA). Todos eles têm a finalidade de aplicação de uma camada protetora de um material com propriedades superiores sobre o substrato (3)(4)(5)(6)(7) . Em qualquer um desses casos, o desafio principal é encontrar materiais resistentes às severas condições de corrosão e ainda que atendam às diferentes condições de temperatura e de tensões (2) .…”

RESUMODentre os processos relacionados à manutenção dos equipamentos que operam nas indústrias do petróleo e gás, a soldagem é uma das mais importantes para recuperação de equipamentos de transporte, de armazenamento e de unidades de refino. Uma das aplicações deste processo neste setor é a aplicação de revestimento com ligas de níquel na superfície interna dos dutos para minimizar o efeito da corrosão. Objetivouse neste trabalho avaliar os efeitos dos diferentes parâmetros de soldagem sobre a resistência à corrosão de revestimentos a base de Níquel depositados sobre o aço API 5L Gr B, utilizado na fabricação dos dutos. Os depósitos de solda para obtenção dos revestimentos foram realizados pelo processo MIG variando os parâmetros de soldagem (

“…TIG-MIG/MAG hybrid welding was first introduced for welding of stainless steel by Kanemaru et al (2014). Then Lou et al (2014) and Meng et al (2014) used this process to weld mild steel and found that humping and undercutting could be prevented at high welding speeds more than 2.5 m/min. Choi et al (2006) reported that a laser beam in front of the arc could suppress bead hump formation through increasing the weld pool spreading and wetting in laser-MAG hybrid welding.…”
