Análise de microdureza de um aço para tubulações por medição in situ e simulação usando welding calculation da nippon steel.

Abstract

The purpose of this study is to verify the validity of software Welding Calculation of welding conditions for qualifying for automation in an API 5L X80 steel. For both experimental profiles were analyzed and compared with the microhardness results in situ for the weld with robotic tubular wire and other for robotic tubular wire and TIG root pass. The results indicated that Welding Calculation predicted values were satisfactory when compared with direct measurements.
