Which is the correct temperature for post weld heat treatment?
A post weld heat treatment (PWHT) at high solutioning temperature (1050-1100 °C = 1920-2010 °F) should be performed, followed by water quenching. The usual low temperature (600-650 °C = 1100-1200 °F) stress relief treatment as used for carbon steel is harmful and must be avoided.See all results for this questionWhat kind of steel is used in electroslag welding?Although electroslag welding is mainly used for the joining of mild and low-alloy steels, satisfactory welds have been made in high-alloy steels, titanium and aluminium. Consumable-guide welding is a much simplified version of electroslag welding.See all results for this questionWhat kind of heat treatment is used to weld stainless steel?For most of the Welding-duplex stainless, a matching composition of filler metal (similar to base metal composition) is used. A post weld heat treatment (PWHT) at high solutioning temperature (1050-1100 °C = 1920-2010 °F) should be performed, followed by water quenching.See all results for this question
Welding-duplex stainless must follow precise instructions
A post weld heat treatment (PWHT) at high solutioning temperature (1050-1100 °C = 1920-2010 °F) should be performed, followed by water quenching. The usual low temperature (600-650 °C = 1100-1200 °F) stress relief treatment as used for carbon steel is harmful and must be avoided.Weld Distortion | Lincoln ElectricThe use of mechanized welding equipment reduces welding time and the amount of metal affected by heat and, consequently, distortion. For example, depositing a given-size weld on thick plate with a process operating at 175 amp, 25 volts, and 3 ipm requires 87,500 joules of energy per linear inch of weld (also known as heat input).WELDING OF STAINLESS STEELS AND OTHER JOINING adjacent to the weld and any differences in the weld filler metal. For purposes of discussion, in welding there are three zones of principal concern: 1) The solidified weld metal, composed of either base metal or base metal and filler metal; 2) the heat-affected zone (HAZ) in which the base metal is heated to high
