No substantiation, no deduction

August 15, 2002

By:

Fabricators should keep records carefully to avoid disallowed deductions and the ever-escalating amounts that add up until the lack of records, documentation, or supporting information is eventually discovered.

Longer slabs, lower costs

August 8, 2002

By:

Unshored, deep steel decking that spans 20 feet—it's a good concept on paper, but can it serve customers in the real world? At least one engineer is convinced it can, and he's taking his message to the masses.

Science Nonfiction

August 8, 2002

By:

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.

Breathing easier

August 8, 2002

By:

Welding smoke and fumes can be dangerous, but there are several types of equipment designed to clean the air welders breathe. Capturing airborne pollutants at the welding source is the most effective technique available. Common designs include source capture arms, portable source capture air cleaners, downdraft or sidedraft tables, and smoke extraction systems. Other air purification devices include ambiant air capture systems and breathing masks and respirators.

Creating finger tooling for three-axis transfer presses

July 25, 2002

By:

Designing finger tooling that will work effectively with a transfer press die is now easier with the advent of modular, off-the-shelf finger tooling components. Through computer-aided design, stampers can minimize trail-and-error adjustments and reconfigure finger tools or modify die components to make part transfer possible.

Camber-free slitting for successful stamping

July 25, 2002

By:

For large volume parts runs, problems such as misfeeds, off-center hits and inadequate transfer webbing can cause slitting-induced strip camber. The production of camber-free slitting requires proper material selection, tooling, techniques and inspection practices.

Estimating your cutting costs

July 25, 2002

By:

In comparing cutting costs associated with precision plasma, punch-plasma, and laser cutting, it's important to account for labor costs, operating costs, and depreciation. All three of these processes have benefits and drawbacks cost-wise, depending on how they're deployed.

Embracing change

July 25, 2002

By:

Automakers are constantly trying to improve automotive designs, making vehicles lighter and stronger, using thinner materials, and redesigning points of strength for better crash resistance. At the same time, welding equipmentmakers who serve the industry are focusing on this quest for quality by developing the equipment to weld hydroformed parts, aluminum, and coated materials: critical components that affect how vehicles are made today.

Reinventing the wheel - Chrome plater develops automated wheel polishing process

July 25, 2002

By:

Kuntz Electroplating, a Kitchener, Ontario-based independent OEM chrome-plating supplier of automotive wheels and bumpers, the management watched as hundreds of its workers manually polished its wheels. Because this made it difficult for the company to find, train, and retain the workers it needed, it decided to develop its own automated process for wheel finishing.

Some 'near-jig' ideas

July 25, 2002

By:

In-process sampling and between-process checks can prevent problems at the production stage. Although using an inspection jig can be costly, some testing approaches that are not as rigorous as using an inspection jig are: stacking and blocking a sheared batch in order to scan the batch for variations; weighing castings; touring a customer's facility; and doing small batch inspections.
