This book contains various topics ranging from testing welded joints on carbon steel and stainless steel duplex pipes, to analyzing the impact of temperature variations in SMAW welding on the microstructure and hardness of ST60 and SS400 steels. Not only that, readers will also learn the effect of using ceramic coatings on the tensile strength of ASTM A36 steel using the SMAW process and the application of basic SMAW welding techniques to improve community capabilities.
