Welding and Joining Guidelines

The main consideration in weld joint design of Ni-/Co-base alloys is to provide sufficient accessibility and space for movement of the welding electrode or filler metal.Slightly different weld joint geometries are required compared to those for carbon or stainless steel; in particular,a larger included weld angle,wider root opening (gap),andWelding and Joining GuidelinesThe main consideration in weld joint design of Ni-/Co-base alloys is to provide sufficient accessibility and space for movement of the welding electrode or filler metal.Slightly different weld joint geometries are required compared to those for carbon or stainless steel; in particular,a larger included weld angle,wider root opening (gap),andWelding Flashcards QuizletButt joint:-two pieces placed edge to edge.The weld should be 100% the thickness of the material.Lap Joint:-most common type of joint,one tube is placed over another.T joint:- also called fillet weld is used in tubular structure to join one tube to another at an angle.The weld should penetrate the base metal by 25%-50% of its thickness.
