CO2 vs. Fiber Lasers

CO2 vs. Fiber Lasers

One of the hottest topics in metal fabricating in recent years has been the growth of fiber laser technology. As often happens with emerging or evolving concepts, there’s a lot of debate and curiosity about the merits of the new machines. Production managers naturally want to know if fiber lasers are better than traditional CO2 lasers, and if so, where and how do they fit?

Stargon SS Meets Customers' Availability Needs

Stargon SS Meets Customers' Availability Needs

It’s hard to believe, but the second-most common element in the universe is getting difficult to come by. Helium has long been considered one of the manufacturing industry’s go-to gases, but today, it’s used for much more than fabrication. Helium has become a critical component in a wide range of applications — everything from party balloons and parade floats to MRI machines and advanced scientific research.

The Microbulk GDS Advantage

The Microbulk GDS Advantage - Praxair

After decades of running his business on compressed air and cylinder packs, Les Ezra is making the switch to a Praxair Microbulk Gas Delivery System (GDS). "I started Ezra Welding Shop in 1968, and in 1993, we changed the name to Metal Fab Engineering, Inc. when we started making parts for automotive restoration,” Les Ezra, Company Founder and President. Metal Fab Engineering’s move to lasers may have been driven by a need to produce consistent, high-quality parts for old Model As and early Fords. But one thing Les didn’t anticipate was the interest in one-off, job shop work.

Your Reliable Source for Acetylene

Your Reliable Source for Acetylene

Acetylene, an “old reliable” among fuel gases in metal fabrication, is experiencing something of a renaissance today. Users are increasingly employing acetylene in processes such as flame hardening in oil and gas field operations and vacuum carburizing for heavy machinery and automotive parts. The semiconductor and glass industries, among others, are creating new uses for this traditional colorless, highly flammable — but highly practical — fuel gas.
