Optimal welding technology of high strength steel S690QL In this paper is presented the detailed procedure for defining the optimal technology for welding the structures made of the high strength steel S690QL. That steel belongs into a group of steels with exceptional mechanical properties.
Prior to presenting the proposed welding For the S690QL steel, the recommended technology, some of the most important preheating temperature should be 150 200 C; recommendations regarding the welding process while the maximum interpass temperature are enumerated [1 - 5]: should be Tinterpass = 250 C in order to prevent 1.
Welding of our S690QL Plates is beneficial, as it reduces substantial material cost, processing and handling expenditures. 2. Lightweight and durable. We specialise in fashioning Structural steel plates in S690QL and S700MC grades, which are notably light weight. Our buoyant and agile steel plates play a great role in manufacturing feather weight structures and machines, consistent enough to provide excellent durability and structural support that last life long.
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. The material is heat treated using the quench and temper process and has good bending and welding properties. Due to the materials high strength nature, using S690QL will promote leaner designed structures with increased payload capacity and energy efficiency.
Our S690Ql is a structural steel grade and is produced to give high yield strength during usage. The material can be heat treated using quench and temper techniques. These EN 10025-6 Plates have good forming and welding properties. S690QL plates have higher payload capacity and are energy efficient, hence can be used in leaner structures. This steel is used in other applications such as heavy transportation, construction industry, machine building, and lifting equipment.
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).

Production flow. furnace. The raw iron is transported in torpedo cars to our own steel shop, where the LD converter refi- nes the raw iron into steel by oxygen blowing, which lowers the carbon content of the iron. It is the carbon content that is the main distinguishing feature between raw iron and steel.
Fabrication of EN 10025 S690QL Steel Plate High strength quenched and tempered steel plate can be easily welded and fabricated but its high yield strength and tensile strength compared with mild steel means that it should be treated with some caution. We have provided information which is intended as a basic guide to various fabrication methods.
S690QL steel (EN steel number 1.8928) is a high yield strength steel which is used in construction and in shipbuilding to lighten structures. It has a guaranteed minimum yield strength of 690 MPa and is supplied in the hardened and tempered state. Its chemical composition is given in Table 1. The welding sheets used here have a thickness of 8 mm, a width of 400 mm and are 1000 mm in length.
Welding, bending and machining Recommendations are found in SSABs brochures on www.weldox.com or consult Tech Support, [email protected] Weldox 700 has obtained its mechanical properties by quenching and subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 580C.
The material is heat treated using the quench and temper process and has good bending and welding properties. Due to the materials high strength nature, using S690QL will promote leaner designed structures with increased payload capacity and energy efficiency. Please refer to the technical details below referring to S690QL.
S690QL Dillimax 690T is a fine grained quenched and tempered steel plate notable for its high strength. S690QL plates are used in a wide variety of engineering applications where strength is important including cranes, critical structural components in building and stadia and pipes and gates in hydroelectric projects.
Any conventional welding method can be used for welding these steels to any type of weldable steel. This brochure is aimed at simplifying, improving and boosting the efficiency of the welding process. It offers good advice on preheat and interpass temperatures, heat input, welding consumables, shielding gas and a great deal more.

D. Arsi et al.: Application of the S690QL class steels in responsible welded structures Materials Engineering - Materilov ininierstvo 20 (2013) 174-183 175 Steels of the S690QL class belong to a group of special, low alloyed steels, where the chemical composition is defined by the delivery
The high-strength structural steel at 700 MPa In the never-ending battle for improved performance of steel products, less weight wins. Strenx is stronger than ordinary steel, you need less material to achieve equivalent strengths in your products.
Filler material For welding of the S690QL steel by manual arc welding, one should use the covered basic redry electrode, or generally speaking, the welding methods that would guarantee low content of Hydrogen in the weld metal 312 V.
