ANÁLISE DA INFLUÊNCIA DO PRÉ-AQUECIMENTO NO AÇO FERRAMENTA VC131 PARA APLICAÇÃO DE REVESTIMENTO COM O AÇO ER308L ATRAVÉS DO PROCESSO DE FABRICAÇÃO GMAW

Abstract

This work discusses the use of weld coating applied to high carbon steel and alloys. This approach justifies the need for parts whose surface requires more resources than the rest of the component to resist the designated work environment. The objective of this work is to analyze the influence of preheating on tool steel VC131 for coating application through the GMAW process. This task will be performed by compositing the ER306L steel cladding layers on the VC131 tool steel, through the GMAW welding process, where various stress and preheat values were performed in the comparison of uses. An analysis has shown little variation in quantities where it was not performed or preheated, or leads to the conclusion that preheating is essential for VC131 steel welding. Another point was the configuration where the lowest voltage range, the lowest dilution percentages or those ideal for coating application already in search of large cable widths, high reform, low penetration and low dilution percentages were used. Unlike conventional applications where high penetration is ideal to ensure weld joint strength.
