In this episode, Jonathan and Alex demonstrate a unique application: welding 420 stainless steel onto copper – a process widely used in the injection molding industry.
In this video, you’ll learn:
- The challenges of welding stainless steel to copper.
- How to adjust parameters to avoid cracking.
- How ALPHA LASER’s recommended settings help you get started faster.
Why this matters?
- Copper molds transfer heat very efficiently but wear out quickly because copper is soft.
- By adding stainless steel along the parting line, the mold’s lifetime is significantly extended.
For this kind of application, we recommend the AL-Flak (from video), ALM & AL-IN laser welders.
