Characteristics of electron beam welding

December 13, 2005

By: ,

Electron beam welding is useful for many applications -- steel, aluminum, and exotic metals; thick, structural sections or thin, delicate components; and harsh conditions such as alternating loads and low temperatures. A programmable controller allows engineers to tailor the electron beam's power distribution, thereby creating a unique weld for each application. EBW often is used in applications that have stringent joint tightness and strength requirements and, in some cases, it is used for welds that cannot be done with any other joining method.

In the loop on closed-loop roll forming?

December 13, 2005

By:

In roll forming, non-stop punching and shear systems have traditionally employed simple open-loop control methods. Closed-loop (also called servo-based) systems can overcome many limitations of the open-loop design and yield higher line speeds, reduce downtime, and reduce scrap.

Looking to higher power for laser speed?

December 13, 2005

By:

Laser beam sources with higher output powers and improved beam qualities have expanded the range of laser applications. Most system's lasers have power higher than 2 kW. Higher power does not always increase the speed, however. Increasing the power during thermal cutting value may cause increased heat-affected zones on the material and place higher demands on the motion system, thus limiting the cutting speed. A new patented cutting machine, the diffusion-cooled CO2 slab laser, may offer improved beam quality and smaller focus diameters under conditions comparable to conventional fast-axial-flow CO2 laser with 4-kW output power.

Creating an efficient offline band sawing system

December 13, 2005

By:

Planning an offline band sawing system can be complicated because it can affect, and is affected by, many interrelated factors. Breaking it down to infeed, sawing, and outfeed helps to frame the planning by breaking it down to three subprocesses. Furthermore, answering 15 pertinent questions can help you tailor an efficient sawing operation to your specific facility and sawing applications.
