There are three main types of welding seams: 1. Longitudinal, 2. Circumferential, and 3. Helical. Longitudinal weld seams are created when two edges of the material are welded together along their length. This type of seam is often used … Ver mais A longitudinal weld is a type of welding joint in which two edges of a rolled material are welded along the lengthwise direction of the part. This type of weld is often used to join sections of pipe or tubing or shell. … Ver mais Longitudinal weld joint efficiency is 0.7 when only visual inspection is carried out. One way to improve the efficiency of longitudinal weld joints is to use spot radiography. A joint … Ver mais The term “longitudinal” refers to the axis of the weld, which is parallel to the length of the workpiece. In contrast, a transverse weld is perpendicular to the length of the workpiece. … Ver mais Longitudinal weld joint falls under Category A as per ASME Section VIII Div. 1. Longitudinal welds are typically stronger than transverse welds because they experience less … Ver mais
