The cryogenics sector encompasses a range of applications including LNG storage, cryogenic pressure vessels, and piping systems. These applications operate at extremely low temperatures, typically around -196°C (-320°F). At such temperatures, many metals that are ductile at room temperature can become brittle, increasing the risk of cracking. Ensuring the integrity and reliability of welds in these conditions is critical to maintaining the safety and performance of cryogenic systems.
When welding for cryogenic applications, it is crucial to control heat input and achieve precise lateral expansion and Charpy V-notch values. These parameters are essential to avoid brittle microstructures and ensure the durability of the materials used. The cryogenics sector requires welds that can withstand extreme cold without compromising the integrity of the structure.
The Spool Welding Robot (SWR™) ensures high-quality welds while carefully controlling heat input, making it ideal for applications that operate at extremely low temperatures.
