UNDERSTANDING THE BASE As with any material, tomorrow's welders will have to understand the chemical and mechanical composition of high strength steel as a first step toward welding success.

9 Rules for Successful Weld Repair of High Strength Steel

Obtain the proper weld procedure from the manufacturer or from an engineer competent in welded Welding of HSLA Steels TWIThere are several reasons for this; a) The high strength of the parent metal means higher residual stresses during welding, b) To match the tensile strength and toughness of the parent steel, the filler metals need to be more highly alloyed and therefore will have a higher CE v, perhaps as high as 0.6CE v (IIW) if matching the tensile strength of a 700MPa yield steel with an E11018 G electrode.Extra High Strength Structural Steel Quend 7001 Steel description and applications Quend 700 is extra high strength structural steel produced as quenched and tempered with a minimum yield strength of 700 MPa.

Semih Genculu, P.E. Arc welding requires striking a low voltage, high current arc between an electrode and the workpiece (base metal). The intense heat generated with this arc melts the base metal and allows the joining of two components.

in strength and an increase in steel cost. Satisfaction was achieved in 1960 with the adoption of A3 6 structural carbon steel having a 36 ksi (248 MN/m2) minimum yield point and a carbon content limit of 0.29% (ladle).

WELDED CONNECTIONS 6.1 If the ultimate shear strength of the weld = fw Rn = fw ×0.707 ×a ×Lw Rn = 0.75×fw ×0.707 ×a ×Lw i.e., factor = 0.75 fw = shear strength of the weld metal is a function of the electrode used in the SMAW process. The tensile strength of the weld electrode can be 60, 70, 80, 90, 100, 110, or 120 ksi.

TWIYes, provided that the welding procedure, particularly any preheat, is designed for the high yield steel. This may mean using basic low hydrogen MMA (SMA) consumables. It is also a convention that the weld metal matches the strength of the weaker of the two components although this is not invariably the case.
