Using 95/5 Shielding Gas During Low-Alloy Filler Rod Conformance Testing
In filler metal qualification tests where argon/oxygen shielding gas mixtures are used, Regis Geisler of Lincoln Electric explains why and how to leave some wiggle room in contracts to make adjustments as the situation warrants, instead of stipulating how welding will take place with a particular blend.
Robotic 3D Cutting Combined with Welding
Flexible systems from Wolf Robotics switch between arc welding, plasma cutting, oxyfuel bevel cutting, pre-heating, etc. using precision tool changers to automate complex parts that once required multiple robots or systems.
Miyachi Unitek Explores Laser Micro Welding Technology at Workshop
The laser technology manager covered the basics of laser micro welding, material and plating selection, part fit-up considerations, and ideal fiber and pulsed Nd:YAG micro welding applications.
Lincoln Electric Names Director of Marketing for North America
Bruce Chantry will oversee all core functions for North American marketing of arc welding products, robotic arc welding systems, fume extraction equipment, plasma and oxyfuel cutting equipment.
ESAB Hosts Legendary Racer at SEMA
Rod Saboury will be the special guest at the show as he receives a 1968 Chevrolet Corvette street racer with a customized 800 hp crate motor that was built using ESAB welding equipment and filler metals.
Storage & Re-Drying Considerations of Low Hydrogen SMAW Electrodes
While executing proper welding technique is the most obvious way to avoid porosity or other defects in low hydrogen SMAW welding, Joseph Murlin of Lincoln Electric explains how the success of the job actually starts well before the first arc is struck.
Best Practices for Using Low Hydrogen SMAW Electrodes
Follow the guidelines in this primer from Joseph Kolasa and Joseph Murlin of Lincoln Electric for applications where base metals have a tendency to crack, where thick sections are to be welded or where the base metal has an alloy content higher than that of mild steel, such as high carbon and low alloy steels.
The Myth of Low-Price Grinding Wheels
To improve your overall cost position, David Long of Saint-Gobain Abrasives examines how premium grinding wheels, cut-off wheels, flap and fiber discs are competitive opportunities for lowering your tooling cost, improving your quality and eliminating the time and cost involved in a key labor area of the operation.
Focus on Proper Weld Size When Developing WPS Parameter Ranges
The fabricator and the erector must determine the most appropriate range of travel speeds for a particular application, rather than relying blindly on published product certs. However, following the methodology presented here by Regis Geisler of Lincoln Electric provides another possible blueprint on how this may be achieved.
Magnets Clamp Steel Gussets and Panels
These unique gusset magnets from Strong Hand Tools allow plane alignment, locating, and clamping of steel gussets and panels and are ideal for assembly, tacking, and welding operations.
Modular Fixturing for Welding
New Titanium-Aluminum angles are part of the latest technology in precision welding tables, components and modular fixturing used for welding from Bluco.
Brush-On Polymer Seals Porosity in Welds
This high-performance brush-on methacrylate compound from IMPCO is formulated for sealing porosity in welds that will contain gases under pressure or liquids.
