To weld pipe with GMAW, you will need a welding machine, a welding gun, a wire electrode, and shielding gas. The process of GMAW is relatively simple: To begin welding, connect the welding machine to the power source to provide the necessary electrical power to the arc.
Pipe welding involves joining pieces of curved metal, making it much more challenging and complicated compared to flat metal sheets welding. It uses a gas-shielded arc welding process to bring together cylindrical metal tubes. TIG welding is the number one go-to option for pipe welding applications.
In this video, our welding expert Christer and material expert Torbjörn will show you how to weld Kanthal® AF strip and wire elements together using a TIG weld and argon as protection gas, as well as how to attach the terminals to ensure solid structural integrity.
Although post weld heat treatment (PWHT) of piping and pressure vessels may be performed in a furnace, weldment size and/or other issues may preclude such heating. In such cases, the weld and adjacent material may be locally heated by one of the methods discussed. Specifically,
2 Ιουλ 2023 · In this article, we’ll delve into the nitty-gritty of pipe welding joints – from socket welds to butt welds and even flanged joints. With this knowledge in your toolbox, you’ll be applying these techniques with confidence and precision, reaping the maximum benefits every single time.
RECOMMENDED PRACTICE FOR LOCAL POST-WELD HEAT TREATMENT. 1. Scope. 1.1 This standard describes recommendations regarding procedures for local post weld heat treatment of welds on pipe fabrication. 1.2 The project contract and specification shall dictate when post weld heat treatment is required.
Pipe Welding Steps. Pipe welding involves several essential steps to ensure a strong, reliable, and leak-free connection between pipes. The typical steps of the process include: Preparation and Fit-Up; Tacking; Welding Technique Selection; Welding; Weld Quality Control; Post-Weld Treatment; Inspection and Testing; Final Checks and Finishing
