Where abrasive waterjets shine

September 14, 2004

By:

Abrasive waterjet's cold-cutting and omni-directional capabilities make it especially well-suited to cutting unusual shapes out of exotic and heat-sensitive materials. Also, because abrasive waterjet is a cold-cutting process, it does not create a heat-affected zone (HAZ), which can make it more difficult to execute downstream processes, such as welding.
