This advanced facility has played a key role in enabling precise evaluation of the reliability of circumferential weld joints, optimizing welding processes, and enhancing the safety of oil and gas ...

The samples were welded by the semiautomatic flux cored and metal cored arc welding processes, which are being increasingly applied in tubular joints at site or pipe shop, due to its high productivity ...

Delve into the essential welding techniques for achieving strong, solid steel joints. This video covers various methods, including MIG, TIG, and stick welding, each suited for different ...

In view of the current situation that all-position welding of pipeline circumferential seams relies on manual welding and automatic welding, this paper proposes four automatic robot operation schemes ...

IRVING, Texas, July 08, 2024--Fluor Joint Venture Moves One Step Closer to Completion and Startup of LNG Canada Train One with Placement of Final Weld ...

The final weld took 48 hours of continuous work from teams of welders working in shifts. More than 380 pipe welders have worked on the project since construction began in 2018.

Most recently, the plant moved to full robotic welding. Four new robot welding cells (each with three welding robots and one handling robot) were installed to complete the bottom-to-shell and ...
