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.
Premium Tungsten Electrodes
These 2 percent lanthanated tungsten electrodes from Weldcraft provide similar characteristics as the 1.5 percent lanthanated tungsten electrode, but with improved arc starting and stability, and less tip erosion. They are also a good substitute for 2 percent thoriated tungsten electrodes.
Automated Welding Increases Productivity
The Franklin plant of mining equipment manufacturer Joy Mining increased productivity and reduced costs in their bit block assembly by converting to automated welding systems from Lincoln Electric.
A Call to Action: The Need to Reform Secondary Education
Parents, schools and private industry can play a key role in better equipping our students for life after school and the full pursuit of the American dream. Nick Peterson of Miller Electric discusses the need to reform the way we think of secondary education and the path it leads to for our children and students.
Finishing Touch: Integrated Plasma Cutting
As the next natural progression in the evolution of mechanized plasma cutting, Jim Colt of Hypertherm explains how many shops are changing the roles of their programmers and the operators by switching to integrated CNC plasma cutting systems that draw more expertise from the CAM database to achieve cut consistency, increased productivity and lower cutting costs.
Welding with Robot Vision
Weld fixtures not repeatable? Inconsistent weld joints? Robots can now automatically adapt to solve these issues and more. Heath Suraba of Lincoln Electric shares some tips on how to see the best return from your vision investment.
