Waterjet is an alternative cutting option. Each cutting process has its strengths and weaknesses; however waterjet is not always the most cost-effective method. As a rule, if the finished product is presently being acceptably cut using laser, plasma or another form of cutting and no secondary work is required, then waterjet is likely not required. When secondary work such as threading a hole, clean up of slag or finish milling, closer tolerance or removal of heat affected zones (HAZ) is needed, then waterjet is the solution.
