Post Heating
About Post Heating
Post Heating is a heat treatment process performed immediately after the welding operation. The welded area is maintained at a controlled temperature to support the reduction of hydrogen content within the weld.
This controlled heating helps minimize the risk of hydrogen-related cracking and supports stabilization of the weld structure after welding.
Post Heating is particularly applicable to high-strength steels and critical weld joints, where controlled thermal treatment is important after welding.
How Post Heating Works
Applications
- High-Strength Steels : Used for suitable high-strength steel welding applications.
- Critical Weld Joints : Applied where controlled post-weld heating is required for critical welds.
Key Benefits
Why Post Heating Matters
Reduces Hydrogen Content
Controlled heating helps reduce hydrogen within the welded area.
Minimizes Cracking
Helps reduce the risk of hydrogen-related cracking.
Stabilizes Weld Structure
Supports stabilization of the weld structure after welding.
