What is WAAM (Wire Arc Additive Manufacturing)?

WAAM is a Direct Energy Deposition (DED) process that uses an electric arc and wire feed to build metal parts layer by layer. Quality depends on stable heat input, melt pool behavior, shielding, and interpass control.

What should you monitor during a WAAM build?

Key signals include thermal history (heat distribution and cooling profiles), melt pool behavior, and interpass temperature. These factors influence bead geometry, microstructure evolution, distortion risk, and defect likelihood.

How can thermal monitoring improve WAAM quality assurance?

Thermal monitoring can detect drift early, highlight hotspots/cooling delays correlated with defects, and create traceable layer-by-layer records (images and metrics) to support QA and qualification review.

WAAM Monitoring Camera for Additive Manufacturing Quality

Wire Arc Additive Manufacturing (WAAM) is a Direct Energy Deposition (DED) process—so quality depends on stable thermal history, melt pool behavior, and interpass temperature. Therness helps teams run in‑situ monitoring and build layer‑by‑layer evidence for qualification.

In‑situ monitoring

What to monitor in WAAM / DED builds

In additive welding, the goal is repeatability. Monitoring focuses on signals that influence geometry, microstructure, and defect risk.

Thermal history

Heat distribution and cooling profiles (layer-to-layer) influence microstructure evolution and distortion risk.

Melt pool behavior

Abnormal melt pool size/shape and unstable behavior can indicate parameter drift and fusion issues. An embedded WAAM monitoring camera such as the HeatCam IR-S captures this layer by layer for repeatable qualification.

Interpass temperature

Interpass control supports repeatable deposition and helps prevent overheating and geometry drift on tall builds.

From monitoring to qualification evidence

WAAM qualification requires repeatability. Monitoring helps you link parameters and thermal response to part quality, and build traceable records for review.

Early drift detection

Catch instability and thermal drift before defects propagate across layers.

Layer-by-layer scoring

Build a quality trail (images, metrics, anomalies) for each layer and each run.

Engineering + QA alignment

Shared dashboards and reports reduce ambiguity between R&D, production, and quality teams.
