Powder Sphericity

The sphericity of the powder describes how round the particles are. Round particles flow better and lead to a denser packing.

Physical-Chemical Mechanism of Action

The sphericity of metal powder determines how well the particles fit together and can be applied in layers. Round particles have a higher fluidity and fill gaps better.

Metallurgical Relevance & Welding Risks

Low sphericity leads to uneven powder deposition, which can cause porosity and inconsistency in the weld. This can affect the strength and toughness of the joint.

Shop Practice & Action Items

For optimal weld quality, use powder with a sphericity of at least 80 %. This ensures a dense, uniform deposit, leading to a quality joint.
