Welding The steel is suitable for all known welding methods. The material temperature should be at least room temperature. We recommended the following preheating temperatures: for plate thicknesses > 20mm up to 75C, > 40mm up to 100C, > 60mm up to 150C and > 100mm up to 175C. Interpass temperature should be between 150C - 225C.

S690QL. S690 QL is a high yield structural steel grade produced in compliance with EN 10025:6:2004. The material is heat treated using the quench and temper process and has good bending and welding properties.
S690QL is a high strength, low alloy structural steel with good weldability and bending properties. This high yield, high tensile versatile product is often chosen by designers to reduce weight in structures.
case of S690QL steels it is generally 6 15 s. Based on the previous statements, we made welding experiments on S690QL quenched and tempered base metal with 30 mm thickness (R p0 ,2 = 809 MPa, R m = 850 MPa, A = 17 %). The aim of the welding experiments was to qualify our welding technology, and make usable welded joints
Welding Weldox or RQT or (generic) S690 Steels. Weldox, RQT and S690 are the same steels and are usually known by the trade name Weldox. They are very high strength steels but have lean compositions (low alloy). Their strength is achieved by thermo-mechanical means: rolling and quenching and tempering (RQT).
Welding can be carried out directly on the excellent Weldox and Hardox primer, due to its low zinc content. The primer can easily be brushed or ground away in the area around the joint. Removing the primer prior to welding can be beneficial, as it can minimize the porosity in the weld and can facilitate welding in

In welding, equivalent carbon content (C.E) is used to understand how the different alloying elements affect hardness of the steel being welded. This is then directly related to hydrogen-induced cold cracking, which is the most common weld defect for steel, thus it is most commonly used to determine weldability.
S690QL S890QL S960QL ASME /ASTM grades and specifications are available to order. Hot forming It is recommended that the RQT range of steels is NOT hot formed. Machining The RQT range can be machined and drilled using high-speed steel or cemented carbide tools. The approximate hardness of the RQT range can be obtained from the
The high yield plates are S690QL and S690QL1 to EN 10025-6 with additional stocks with yields at S890QL, S960QL and S1100QL. These plates are typically used by crane manufacturers, in jackup rigs for the oil and gas industry and in a variety of structures where high yield steel is required for additional strength and/or to save weight.
