Join Jonathan and Alex for a new episode of ALPHA Welder! In this video, we showcase the laser welding repair of a worn impeller, focusing on a deep inside diameter (ID) buildup using the ALFLAK 1200 fiber laser, paired with turn & tilt optics and the AL-DV wire feeding system.
The challenge? A 4.5″ diameter hole over 6″ deep that requires precise welding from both sides. The solution? High-precision laser buildup in multiple layers (60 thou per side), maintaining part integrity and avoiding distortion.
Benefits:
- Deep and accurate welds even in hard-to-reach areas.
- Minimal heat input = reduced risk of cracking or warping.
- Clean, repeatable results with minimal post-processing.
- Visual real-time control and fine-tuned pulse settings (21 Hz).
This episode covers:
- Multi-layer wire welding inside small-diameter components.
- Smart handling with 180° part rotation for full access.
- Consistent process development using certified WPS procedures.
- Real-world repair strategies with measurable results.
Discover how laser welding is revolutionizing repair work in the industrial sector—saving time, reducing cost, and preserving critical components.
