1. Analysis of Residual Stress by the Hole-Drilling Method and Hardness in Dissimilar Joints of Austenitic Stainless Steel AISI 316L and Inconel 718 Alloy by Autogenous GTAW Process
Stainless steel and nickel alloy have high corrosion resistance in high-temperature environments due to the high Cr content present in their chemical composition, being widely used in components of nuclear reactors, petrochemical industries, etc. Through proper processes and procedures, it becomes possible to join these alloys. However, this union can genera

2. A Study on out-of-phase current pulses of the double wire MIG/MAG process with insulated potentials on coating applications: part II
This paper presents a continuation of a study carried out on the use of the out-of-phase current pulses technology applied to the Double Wire MIG/MAG welding process with Insulated Potentials on welded coatings. In the first part it was reported how the level of out-phase pulsed current acts on arc configuration, droplet paths, bead finishing and arc stabili

3. The shielding gas influence on the ferritic stainless steel weld / InfluÃncia do gÃs de proteÃÃo na soldagem MIG/MAG do aÃo inoxidÃvel ferrÃtico com arames ferrÃticos
The ferritic stainless steel has been large used, mainly in the automobile industry. One of the most important advantages of ferritic stainless steel is its lower price, if compared to austenitic stainless steel, due to absent of, nickel which is an expensive component. The ferritic stainless steel is tradittionaly welded using austenitic wires to asure good

4. Welding Residual Stress Evaluation of Small Size Pipes Used in Petroleum Refinering / AVALIAÃÃO DAS TENSÃES RESIDUAIS DE SOLDAGEM EM TUBULAÃÃES DE PEQUENO DIÃMETRO USADAS EM REFINARIA DE PETRÃLEO
The aim of this work was to evaluate the behavior of welding residual stress in small size pipes of ASTM A106 Gr. B steel, welded by manual and automatic GTAW processes. It was also evaluated the effect of the welding heat input on residual stress profile, as well as to correlate the results with microstructure and hardness. The residual stress measurement w

5. Influence of the weld parameters on metal transfer and weld bead profile in double wire MIG/MAG process / Influência da variação de parâmetros de soldagem sobre a transferência metálica e perfil do cordão no processo MIG/MAG duplo arame
Double Wire MIG/MAG welding process appeared in manufacturing market as an alternative for metals joining, when highest productivity is demanded. However, the most important limitations of this process is the difficulty for parameter settings, as much because of doubled parameters in relation to the normal process as because each wire is dependent of each ot
