 high-quality joints with a small heat-affect- ed zone, consistency in weld duplication and faster weld times. The process, note Coldwater officials, also is environmentally cleaner and safer with no filler material, spatter, smoke, radiation or shield gasses.
“With the move toward lightweighting, OEMs are looking for the most effective way to cut weight without sacrificing quali- ty or safety,” says Tim McCaughey, Coldwater Machine president. “The existing tech- nologies needed to process these lighter materials typically add weight or cost, result in low weld strength, or have porosity defects. Our friction spot-welding system overcomes these issues and is efficient enough to run in a production environment.”
SpotMeld friction-stir spot welders can be configured to application specifics and mounted on any industrial robot, with a vari- ety of weld recipes available on demand via the robot controller. www.coldwatermachine.com
Waterjet Intensifier
Pump for Shops
with Limited Power
Jet Edge, Inc., St. Michael, MN, has developed a waterjet-cutting pump for shops that desire the reliability of a hydraulic intensifier pump but have limited power. Dubbed the iP60-30, the 60,000-psi, 30-hp (22 kw) pump draws only 37 full-load amps at 460 VAC (60Hz), or 74 full-load

amps at 230 VAC. It can produce 0.6 gal./min. of ultrahigh-pressure water at a continuous operating pressure of 55,000 psi.
the iP60-30 features a tie-rod design that eliminates threads on the high-pressure cylinders, end caps and hydraulic cylinders. This reduces the likelihood of cracking and increases component life. The pump includes a hydraulic accumulator to provide smooth hydraulic pressure, reduce spikes and prolong hydraulic pump life. www.jetedge.com
Ideal applications, say Jet Edge officials, are rural fabrication shops, research and development labs, schools, and small budget-conscious waterjet-cutting shops.
Like all Jet Edge intensifier pumps,
