Three common cutting methods of S690QL steel welding cutting

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, S690QL steel welding and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

SA516Gr60 meets the requirements of (ASME) ASTMA516/A516M standards, and meets the needs of oil gas with high content of sulfur and hydrogen, reducing sulfur and hydrogen corrosion, reducing equipment maintenance, and increasing equipment life. The steel S690QL steel welding has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-layer cracking performance, microalloying, high purity, low carbon equivalent, and strong resistance to sulfur and hydrogen.

Medium and thick steel plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on. However, each project has different requirements for plate size. How to cut S690QL steel welding, medium and thick steel plates? There are many ways, for example, flame cutting, laser cutting, wire cutting, plasma cutting, ultra-high pressure water cutting and so on.
