A metal additive method, comprising directing one of sonic and ultrasonic energy from a probe that is directed toward a melt pool during solidification of the melt pool and formation of a layer, wherein a solid portion of an object on which the pool is positioned at least partially surrounds the melt pool.
A system comprising:
- a welder configured to form a melt pool on at least a first part;
- an acoustic noise probe configured to direct acoustic noise toward the melt pool during solidification of the melt pool and formation of a first layer on the first part;
- and
- a controller configured to position the noise probe proximate the melt pool and generate the acoustic noise.
A controller for controlling a welder, the controller configured to:
- cause the welder to form a weld pool on at least one part;
- direct an acoustic noise probe toward the weld pool during solidification of the weld pool;
- and
- position the noise probe proximate the weld pool and generate acoustic noise during formation of a first layer on the at least one part.
