Resumo
Different types of welding wire are found in the market in general, but one of the most used by the automotive market is solid wire. On the other hand, tubular wire, known as “metal core” began to be also used by this industry, but with a much lower proportion due to lack of studies on it. This study was conceived with the purpose of contributing with further clarification regarding the use of tubular wires AISI 439Ti, in automotive exhausts welding, composed of AISI 1018 carbon steel and stainless steel AISI 409 and AISI 439 instead of solid welding wire AISI 307Si. To analyze the test specimens produced during this study, the following tests were used: micrographical analysis, fatigue, thermal fatigue, penetrating liquid and sensitization according to ASTM A763. The obtained results demonstrated the greater efficiency of the tubular wire compared to the solid wire.
