Repair Laser welding on ID of an Impeller | ALPHA Welder

Join us for a new episode of ALPHA Welder as we return to Phoenix Laser Solutions in Meadville, Pennsylvania!

In this episode, we demonstrate 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.

Why choose laser welding for impeller repairs?

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)

Using the ALPHA LASER system, we highlight:

✅ 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.
