Wire-Arc Deposition with ER70S Wire — Cell View and Close-Up
MAG wire-arc deposition with 1.2 mm ER70S wire, as the caption on the clip states: first the torch in the cell, then a close-up of the torch and the melt pool moving along the bead.
Short, tapered profiles such as a gear tooth are a demanding test for WAAM: accumulated heat has nowhere to escape and slumping shows up first. In the close-up you can follow the torch and the melt pool along the bead; that pool has to solidify enough to support the next bead before it lands, while still fusing to the layer beneath. Get the balance wrong and the part either bulges as the pool sags or leaves cold, poorly bonded interfaces. The lever that controls this is interpass temperature: hold each new layer within a defined window and the near-net-shape stays true and the microstructure stays uniform, which is why measuring layer temperature between passes — not just at the start — is central to keeping a WAAM part printable and inspectable.
What you see
- The torch at work in the cell, then a close-up camera following it along the bead.
- MAG deposition with 1.2 mm ER70S wire, as the caption on the clip states.
- The melt pool under the torch and the glowing bead it leaves behind.
- A vertical clip of 15 seconds.
Monitor it with Therness
- HeatCam thermal sensors read layer and interpass temperature live.
- HeatCore AI flags overheating and process drift before a layer fails.
- Layer-by-layer thermal records build QA evidence for every part.
- Works on carbon steel, titanium, and nickel WAAM builds.
