@BrazilWeldsMessiasCarvalho Filmed December 2017 - Please give me friend Messias a follow/subscribe to his YouTube channel! He has a wealth of knowledge, skill and talent and has some of the most incredible welding videos! Especially his Duplex Welding videos that have a root and cap pass, all at the same time, or the videos of him as a Supervisor working in different parts of the world with his crew of highly talented Welders! ☺️
