The American Conference of Governmental Industrial Hygienists recently recommended a tenfold decrease in exposure limits for manganese, which are present in welding fumes. This is big news because OSHA typically uses these recommendations as the basis for future regulation updates. Big changes could be coming for metal fabricators
Modern plasma systems can do more than just cut. They can gouge, mark, remove welds, and more. And this applies whether plasma processing occurs using a hand-held torch or a machine torch mounted on a CNC table, robotic arm, or automated track.

Plate and angle rolling remains extremely dependent on operator skill. According to a U.S. roll shop roundtable discussion held at a Davi angle rolling event in Italy, that skill really is what sets a custom rolling operation apart.

Perfectly accurate inventory records will help you improve turns, which frees up cash; improve customer service, because you know what you have when a customer calls; increase shop productivity, because material will be available when needed; and increase profitability, because you won’t be writing off inventory that isn’t there.

When communication is visual, we see together, know together, and therefore act together.
Lubrication plays an important role in sheet metal forming by affecting metal flow and reducing the possibility of fracture during forming. A number of tests are used to evaluate lubricant performance, including the strip draw test, the twist compression test, and the cup drawing test.The cup...

A fabricator’s marketing function shouldn’t be about tradeshow booths, brochures, and websites. It’s not there simply to serve the sales function. Instead, marketing reinforces a fabricator’s value proposition and, ultimately, helps drive the direction of the business.

Tooling is of course a significant cost driver in roll forming. But reducing costs takes more than scrutinizing the number of passes a roll formed cross section requires. It also calls for looking at the big picture and questioning the status quo.

Miter cutting tube and other workpieces can be extremely critical, especially when dealing with frameworks and other large assemblies. One seemingly small error in a miter cut can throw a large assembly significantly out of tolerance. This is where automation and precision control in sawing come into play.

Laser welding is a great process for delivering high-speed joints with a small heat-affected zone, but it requires consistency in gap size. Gas metal arc and tandem welding, on the other hand, handles those inconsistencies in gap size much more easily. Combining the processes has proven to be a manufacturing success for some automakers.
