CO2 lasers were used predominantly for cutting flat sheet metal for many years. Advancements in laser beam quality, power, manipulation, and material handling features have propelled the CO2 laser into new areas of fabrication. Multidimensional cutting, increased cutting capacity, and the ability to cut a wider range of material types make the CO2 laser a popular thermal cutting process in today's metal fabrication industry.

Editor's Note: This article is Part II of a four-part series covering flatness and stability in cut-to-length, slitting, and tension leveling operations. This article discusses flattening solutions and the anatomy of a bend. Part I, which appeared in the October issue of The FABRICATOR®, discussed how flat-rolled metal gets unflat; Part III in the December issue will address how coil processors can make metal flat so it stays that way; and Part IV in the January 2003 issue will discuss new applications and options in leveling equipment.

Metal cutting lasers continue to evolve at an amazing rate, largely based on the demands of OEMs and job shops, while profit margins shrink because of increased competition and lower pay rates. To help fabricators meet the demands placed on them, laser manufacturers are creating new laser features that help fabricators differentiate themselves, speed up productivity, and get more out of their laser machines.

This article discusses the history of lasers and material handling equipment with relation to unattended operation. It specifically examines material load/unload devices, sheet separation and detection devices, the auto-focus laser lens, raw material storage and retrieval systems, automatic part sorting systems, problem notification systems, cut control devices, and nozzle cleaning equipment.

Here's some food for thought on lasing gases: How are they created? What are their potential impurities? Which impurities and how much of them are of concern? What lasing gases should be used? How do you protect yoiur high-quality lasing gases from contamination? Giving these items some attention could save you some trouble down the road.

The most common power levels ranged between 1,500 and 2,000 watts. However, a statistical survey conducted by the AMT Laser System Product Group indicates a steady increase during the last 12 months of installations for high-power 3,000- to 4,000-watt laser systems and a decline in sales of lasers with power levels less than 2,000 watts.

Applying a laser or any other high-density heat source to the surface of a metal sheet for a short time will distort the metal. If this distortion could be predicted, the laser could be directed so that the sheet metal would form the desired shape. This idea opens up many possibilities, including...
