In stainless steel fabrication, surface fractures often arise due to incorrect welding methods. One major issue is excessive heat buildup in the welded area, causing brittleness and eventual cracking.
Why Do Stainless Steel Welds Crack?
The welded area may appear overly thick due to multiple passes. This can lead to:
- Over-penetration of the weld
- Localized overheating
- Loss of material ductility
- Heat-Affected Zone (HAZ) brittleness
When stainless steel becomes brittle, especially near weld seams, it compromises the product’s strength and appearance.
Spot Welding – A Smarter Alternative
Instead of continuous welds, spot welding offers a cleaner, more controlled approach:
- Minimizes heat input
- Reduces material distortion and burn-through
- Saves time and material
- Enhances surface aesthetics
This is particularly useful for stainless steel pipes and tubes used in architectural, industrial, or furniture applications.
What Can Suppliers and Engineers Do?
If you’re manufacturing or sourcing stainless steel welded pipes, consider:
- Implementing spot welding in thin-walled applications
- Auditing weld quality to avoid overheating
- Choosing suppliers with experience in precision welding
