FABRICATION
Today’s fabricating technology promises the ability to produce high-quality components job after job, in a variety of applications. And, in each issue, MetalForming is committed to informing you on how fabrication equipment delivers.
This month, MetalForming’s Fabrication section covers a variety of topics, including grinding tips and tricks, the applications where plasma cutting shines, and the tricky task of resistance spot welding advanced high strength steel in automotive applications. In addition, we profile TOA USA, a Tier-One auto supplier that recently upgraded its enterprise resource planning software to better track and analyze internal operations as well as its supply chain.

Handheld 3D Scanner Offers High-Speed Data Capture and Processing
The new Artec LEO 3D scanner from
Exact Metrology, Inc. can scan both
expansive areas and fine details, as well
as a variety of objects, including small
parts. Offering onboard automatic pro-
cessing with an integrated touch panel viewer, the handheld scanner frees users from being tied to a com- puter for data capture.
The scanner features a rapid 3D reconstruction rate
of 80 frames/sec., reportedly making it the fastest pro-
fessional scanner on the market, and provides
a large field of view. Data acquisition reaches
4 million points/sec., with a working range of
0.35 to 1.2 m. It provides 3D resolution to 0.5 mm and 3D point accuracy to 0.1 mm. State-of-the-art technologies incorporated into the Artec LEO include its internal computer, the Nvidia Jetson platform, and a built-in 9 DoF inertial system, including an accelerometer, gyro and compass, that allows the scanner to understand its position and environment. And, a two-in-one optical system is designed to specify the most exact texture-to-geometry mapping.
With no need to connect to a computer or to plug in to a main power source, users can hold the scanner and walk around freely, scanning without worrying about wires or additional equipment. Artec LEO’s battery pack allows users to scan for 3.5 to 4 hr., while supplementary battery modules permit unlimited 3D scanning in remote areas. Exact Metrology, Inc.: www.exactmetrology.com
Twin-Wire GMAW Ups Productivity in High-Deposition Welding
Lincoln Electric’s HyperFill, a patent- pending twin-wire gas metal arc welding (GMAW) product developed for semi- automatic and robotic applications, increases the usable deposition rate as compared to traditional single-wire GMAW while delivering improved weld quality and puddle stability, according to company officials.
With its twin-wire design, HyperFill
can utilize two smaller-diameter wires
to produce a larger weld droplet and arc cone. In return, this generates a large weld puddle that is easier to manage and control, reportedly allowing operators on average to increase usable deposition rates to 50 percent as compared to traditional single-wire processes.
And, unlike traditional twin-wire processes, which typically require dual power sources or dual contact tips, HyperFill uses a single power source, feeder, gun liner and contact tip. This allows operations to improve weld deposition without complex system setup.
