With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Optimal welding technology of high strength steel S690QL. However, this steel has a negative characteristic - proneness to appearance of cold cracks. That impedes welding and makes as an imperative to study different aspects of this steel's properties as well as those of eventual filler metal.
S690QL Welding . S690QL steel is suitable for all current welding methods. The temperature of the material should be at least RT for welding. In addition, the following preheating temperatures are recommended for certain plate thicknesses: 20mm 40mm: 75C Over 40mm: 100C 60mm and over: 150C These indications are standard values only, in principle, indications of SEW 088 should be adhered to.
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.
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

welding with unalloyed or low-alloyed welding con-sumables. Solid wires used in MAG and TIG welding can produce these low hydrogen contents in the weld metal. The hydrogen content for other types of welding consumables can best be obtained from the respective manufacturer. Examples of consumables are given at www.ssab.

Welding Weldox or RQT or (generic) S690 Steels. 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). These days they find use in all sorts of fabrications from battery powered vehicles to skips,best welding s690ql
Basic Stick Welding Electrode Selection. A good example of what the strength of a weld is the rod numbers themselves. A 6011 rod using the first two digits (60XX) stands for a minimum of 60,000 pounds of tensile strength per square inch of weld. A 7018 is 70,000 pounds of tensile strength per square inch.
The t 8/5 times should be between 5 and 25 s, depending on the welding technique used. Should stress relief annealing be necessary for constructional reasons, this should be done in the temperature range of 530C-580C S690QL1 Quenched and Tempered Structural Steel
Aesteiron Steels LLP-As a popular distributor S690QL High Yield Steel, we export a wide variety of S690QL High Yield Steel in all over India and overseas, exporting best quality S690QL High Yield Steel to our clients.
Dillimax 690 (~S690QL) recommended H.I during welding is given below t 8/5 : Is the time in which the temperature of a bead drops from 800 C to 500 C is generally used to describe the heat cycles occurring during welding.
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.
(S690QL is similar to Weldox 700) and see what they advise for welding these materials. Always use heat imput as low as possible for same reason as why omitting PWHT, especially in case where fatigue also can become a problem. Best Regards, Herman Pieper.

S690QL plate is an excellent material. It is of high and consistant quality through out. It's flatness is good, and so is the surface finish. And it is also easy to machine. Neither welding nor blending ever gives any problem. S690QL is the best structural steel for larger trailers.
base material (c) and S690QL welded microstructure. C. Weldability of S690QL steels . The production of the high strength steels result in non-equilibrium microstructure, which alters the welding process irreversible, hence the original microstructure can be not repositioned after the welding. The heat affected zone can be easily hardened,
