Japanese metal fabrication: Manufacturing on a bedrock of data

October 14, 2008

By:

Overseas, metal fabricators have many of the same issues as those stateside, including lack of skilled labor and outsourcing to low-labor-cost countries. In Japan, fabricators tackle those issues by taking automation to new levels.

Pallet changer, tower, or shelving system with that laser?

October 14, 2008

By:

When fabricators decide to automate material handling in their laser cutting operations, they have several choices to make. The decision on whether to automate—and what kind of system makes the most sense—will depend on the shop's capabilities, its production capacity, and available floor space. The options cover the full spectrum, from basic systems that simply unload one pallet and bring in another to large racking systems that maintain a full inventory of raw material and cut parts and can transfer those parts to other machines in the shop.

Welding with diode lasers

October 14, 2008

By:

High-power diode lasers are just beginning to make an impact on welding applications. They are also physically smaller than other lasers, and their initial capital cost is not as large as it might be for traditional welding lasers because diode lasers have fewer system components.
