What are the influencing factors of flame cutting quality for acero S690QL

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of acero S690QL, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

In 2019, the output of pig iron in the world was 1.265 billion tons, with China accounting for 64%; the overseas output accounted for 36% (460 million tons), ranking 86.982 million tons of EU 28 countries, 74.907 million tons of Japan, 74.099 million tons of India, 73.264 million tons of CIS, and acero S690QL 47.521 million tons of South Korea.

Q960 quenched and tempered steel has excellent low temperature toughness, so it can be used in large welded structural parts and low temperature environments.
Excellent welding performance of Q960 quenched and tempered steel: The composition design minimizes the carbon content and thermal sensitivity coefficient to improve the welding performance. So, acero S690QL, Q960 steel has excellent welding joint performance, which can meet the welding requirements of bridges, buildings, cranes, shipbuilding, vehicles and large structural parts.
