The effect of post weld heat treatment on welds in steel structures

1983
The effect of post weld heat treatment (PWHT) on residual stresses, yield strength and toughness as well as on microstructural features of submerged are weld metal was studied with three types of C-Mn-steels. All techniques used for measuring residual stress reduction in PWHT were found insufficient to adequately characterise the stress distribution ...

Post Weld Heat Treatment of Oilfield 13Cr Stainless Steels

CONFERENCE 2024
Abstract Type 13Cr martensitic stainless steels are widely used for threaded and coupled oilfield casing and tubing because of their resistance to corrosion by dissolved carbon dioxide and their cost advantage over most other corrosion-resistant alloys. However, 13Cr used for welded downhole components requires careful planning.

The effect of post-weld heat treatment on microstructure of AISI 316L steel

2007
Excellent mechanical properties and good corrosion resistance of austenitic stainless steels may become affected by microstructural changes occurring as a result of welding followed by heat treatment. An investigation was carried out on welded AISI 316L steel joints produced by manual electric arc welding technique and then submitted to post-weld heat ...

Critical Factors in Optimizing Post-Weld Heat Treatment for Structural Integrity

Volume 4: Gas Turbines; Pressure Technologies; Robotics & Automation
Abstract The 2014 Edition of ASME B31.3, Process Piping, introduced significant changes to the post-weld heat treatment (PWHT) requirements for P-No. 1 carbon steel materials. According to the revised code, PWHT is no longer mandatory for any wall thickness, provided a minimum preheat of 95°C (200°F) is applied for nominal material ...
