How do I troubleshoot common welding defects?
Welding defects can impact the quality and durability of your welds. Let’s explore some common welding defects, their causes, and preventive measures:
Weld Cracks:
- Cause: Excessive stress during cooling or poor joint design.
- Prevention: Proper joint preparation, controlled cooling, and avoiding abrupt changes in direction.
Porosity:
- Cause: Trapped gas bubbles in the weld.
- Prevention: Clean base metal, proper shielding gas, and correct electrode handling.
Undercuts:
- Cause: Excessive current or incorrect travel speed.
- Prevention: Maintain consistent travel speed and adjust parameters.
Overlap:
- Cause: Incorrect weaving motion or excessive current.
- Prevention: Proper weaving technique and optimal current settings.
Excessive Spatter:
- Cause: Molten metal splattering during welding.
- Prevention: Adjust voltage, clean surfaces, and use anti-spatter compounds.
Remember, regular inspection and adherence to best practices help prevent these defects.
