Longitudinal Weld: Everything you want to Know. - Material Welding
Oct 23, 2022 · 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.
Weld Joint Category as per ASME Section VIII Div 1 UW-3
Here we have two main types of weld joint. Longitudinal weld Joint; Circumferential Weld Joint; Longitudinal Weld Joint : Weld Joint is done along the length or along the longitudinal direction is called as Longitudinal Joint. This Joint is also Called as L – Seam Joint or Long Seam Joint.

To properly size a weld, it is essential to know what loads are transferred through the connection. For transverse splices, this is a relatively simple task. For longitudinal welds, it’s not so simple. Figure 1 Figure 2
involves longitudinal welds on built-up beam and column sections. These welds are typically loaded in shear, which rarely requires the strength of CJP groove welds. Fillet welds or PJP groove welds are typically better, lower-cost options for this case. Fillet and PJP welds are also typically the more
Longitudinally Welded Pipes - wermac.org
Longitudinally welded tubes are used for: posts, drilled posts, mooring posts/fenders, jetties. Pipes welded under powder coating (LSAW) have been used for decades to transport large quantities of hydrocarbons over long distances.

2. LONGITUDINAL WELDS. The highest category for longitudinal welds, 140, applies only where there are "no significant flaws". This implies automatic welding, no stop/start positions, no slag inclusions or blow holes - near perfection "demonstrated by specialist inspection".
The choice of transducer refractive angle (K value) for ultrasonic testing of curved longitudinal welds is affected by the pipe diameter and wall thickness, and the selection is based on ensuring that the sound beam can achieve full coverage of the entire tube wall weld and heat
Longitudinal Welding Made Easy with this Complete Solution.
Jul 11, 2016 · Longitudinal welding can be undertaken using various welding processes. These include MIG, TIG, plasma (PAW) and submerged arc (SAW). Used in applications such as pipe welding, water tanks, boilers, cryogenic tanks and storage tanks, …
longitudinal submerged arc welding processes | Total Materia
Longitudinal Submerged Arc Welding is a specific welding technique used in pipe production where the finished product requires a particularly high wall thickness due to high internal or external pressures.
Welding Techniques: Circular Seam Welding vs. Longitudinal Seam Welding ...
Sep 27, 2023 · Two commonly used welding techniques are circular seam welding and longitudinal seam welding. Each method has its own unique characteristics and applications. In this article, we will explore the differences between these two welding techniques and their respective advantages and disadvantages.
