Does a punch/laser combination system make sense for your operation? For the answer, consider these five factors: part geometry; process throughput; lean manufacturing; process flexibility; and automation.

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.

There’s always room for improvement in any operation. Following these seven steps can help you identify areas that need improving and put your shop on the path to optimal efficiency, increased productivity, and less waste.
How many lasers and punch presses do you have? How many press brakes? Determining the best ratio isn’t as straightforward as it once was. It’s a puzzle that must be looked at holistically. The trick is discovering which pieces fit best for your operation.

Earlier this year Worthington Specialty Processing, a toll processor serving the automotive industry, among others, installed a continuous-feed, coil-fed laser blanking line. An idea with roots in the 1990s has finally become reality.

Honda used Gestamp’s in-die “softzone” hot stamping process to form strategic zones of the 2016 Civic sedan’s rear frame rails to 1,500-megapascal (MPa) (shown in red), while cooling other zones (shown in pink), at a different pace to render them to a lower tensile strength to satisfy crush mode and performance targets.

After peaking in June, steel prices continue to decrease. Metal fabricators should keep an eye out for price increases from the mills. When they are announced, service centers will begin increasing their own prices.

Q: I find myself rejecting a lot of welds. I don't want to fail them and find out that I misinterpreted something. When there are small amounts of undercut throughout the length of the weld, I'm still not clear on what AWS means by "... in 2 inches up to 12 inches" [AWS D1.1, Table 6.1(7)]. So I...
Q: A majority of our welding is done on 1/4 to 5/8-in.-thick carbon steel that has a weldable primer. Most of the welding is done on basic partial joint penetration (PJP) T-joints without any joint prep. We use an E70T-1 0.052-in.-dia. flux-core wire with a 75 percent Ar/25 percent CO2 shielding...

This month’s topic doesn’t deal specifically with welding aluminum, but I think you will agree it has important implications in the design and fabrication of aluminum structures. This topic and its associated problems have come up in conversations twice in the past two months. It deals with...

Vehicular weight reductions that automakers have made largely have been attributed to the use of advanced high-strength (AHS) materials—and the stamping manufacturers forming them. Stampers have muscled the Olympian feat via many approaches, including using servo-driven mechanical presses. Servo presses have evolved and moved from the fringe into the mainstream. Four servo press manufacturers weigh in on how servo press technology has advanced to spot stampers in helping them meet the challenges inherent in forming superstrong metals with low formability and high work hardening.

The SUPERB™ factory in Sugarcreek, Ohio performs surprisingly high-tech operations in a traditional village in Amish country, including stamping components for next-generation power grid storage units for Alevo. To meet the demand to stamp and assemble 100 million battery components, the manufacturer installed automated assembly equipment.
