WaterJet & Fabrication

Abrasive waterjet cutting (AWJ) and fabrication go hand-in-hand. But while AWJ is a specific cutting technique, that uses very specific equipment, fabrication refers to a wider range of techniques.

Abrasive Waterjet Cutting

AWJ uses a high-pressure, high-speed jet of water to cut material by what is termed rapid erosion. Unlike the various thermal cutting processes, it doesn’t use any form of high-temperature melting or oxidation of the metal that typifies oxygen fuel gas cutting. It does though sometimes utilize finely ground abrasive materials that are included in the jet of water.

Waterjet cutting produces a cut that is very similar to one that has been flame cut. Additionally, the way the jet of water is directed to the surface of the material to be cut is very similar to the technique used with oxygen fuel gas cutting torches. The solid stream of water also acts in a way that is very similar to the stream of oxygen produced during thermal cutting.

AWJ has become a popular alternative to the thermal cutting processes and it is frequently the process of choice for automatic shape-cutting machines because it produces cut parts that have a contoured shape. There are other advantages of waterjet cutting including the fact that no lateral force is needed. Also, because no heat is involved, there are no metallurgical changes on the cut surface of metals, and heat thermal distortion isn’t a problem. And above all, it isn’t only metal that can be cut. Other suitable materials include plastics, glass, wood, rubber, stone, and even cardboard, so it’s a good option for packaging products.

Fabrication Techniques

Basically, when items are fabricated, they are made from raw or semi-finished materials. Other manufacturing processes involve assembling items from ready-made components or parts.

Metal products are commonly fabricated either by cold working (hammering, pressing, rolling, bending, or by being drawn) or by hot working by soldering, brazing, or welding.

MESH Automation’s Waterjet and Fabrication Services

MESH Automation has a Flow Mach 3 abrasive waterjet that uses 60,000 psi to cut materials as thick as 8” with a cutting envelope of 60” x 120”. Its dynamic head feature compensates for taper (within .003” on 1” thick material.) This will produce two-dimensional (2-D) parts with tighter tolerances at higher speeds than other waterjets without this feature.

Our waterjet equipment can handle a wide range of materials including:

  • All metals
  • Plastics
  • Polycarbonate
  • Ceramics
  • Foam
  • Phenolics
  • Wood
  • Granite and marble

MESH Automation’s welding capabilities include metal inert gas (MIG), tungsten inert gas (TIG), and manual metal arc (MMA) or stick welding of aluminum, stainless steel, and carbon steel, with all work performed by our skilled tradesmen to American Welding Society (AWS) standards.
