Super Bowl XLVI in Indianapolis earlier this year featured athletic prowess and classic gridiron toughness with a little speed and finesse. But also on display outside the stadium throughout the heart of downtown was a combination of strength and artistic flair that only a metal art sculpture can provide.

A truly remote-controlled foot pedal for TIG welding sounds like the perfect tool for job site fabricators, but welders that work in a small cell are also finding advantages associated with cutting the welding control cord.

The concepts of positioning are the same for all weldments, large or small. A properly positioned weldment, regardless of the size, reduces welder fatigue, increases safety, improves weld quality, and saves on production floor space.

Portable calibration units allow you to perform quality assurance maintenance themselves by calibrating critical welding variables on-site. These remote servicing capabilities bring support closer to the jobsite, improving the uptime and functionality of the power supply and eliminating the need to send it off-site for calibration.

After working for a few years making leather belts and belt buckles, Anthony “AJ” Patti moved on to designing and manufacturing leather goods for Harley-Davidson, then went on to pewter casting to make jewelry for the venerable motorcycle manufacturer. An artist always striving for efficiency and mass production, Patti’s latest venture is making sculptures and adornments for gardens.
Welding novices might be confused by terminology commonly used by fellow welders but not found in standard glossaries. This article defines some of these terms used in shielded metal arc welding.

The major cause of a crack is when internal stresses exceed the strength of the weld metal, the base metal, or both. Knowing the basics behind why cracks happen, a welder can prevent those cracks from occurring in the first place.

The push for lighter, corrosion-resistant components has brought aluminum to the forefront of the minds of traditional steel fabricators. Those that approach the material the same as steel often run into weld quality issues that can prove costly. But those who are committed to putting together a topnotch, aluminum-friendly system before striking an arc—from equipment and setup to material preparation and welder education—are better equipped to find success afterward.

A career in code-level welding involves an odd concoction of hands-on work, excellent hand-eye coordination, on-the-job focus, and a dash of lawyerlike thinking. Some can be loud extroverts who get the most attention, but others can be quiet introverts. Many share a dedication to the welding craft, and the best strive to do the job right the first time.

Cup walking, a tube or pipe gas tungsten arc welding (GTAW) technique suitable for some stainless steels, can improve weld quality. The method involves resting the torch’s cup on the workpiece and making a weaving motion across the weld joint. Used properly, it also reduces operator fatigue and can improve weld speeds.

Metal-cored wire typically costs more than solid wire, but the benefits often offset the per-unit price. In reality, any consumable comprises a relatively small portion of overall welding costs; in fact, material and labor make up the lion’s share of welding expenditures. But in the right application, an increase in filler metal costs may lead to greater savings elsewhere.

In a 2010 survey from the Fabricators & Manufacturers Association, respondents cited welding as the most sought-after, difficult-to-find technical skill. But at Mitchell's Specialized Fabrication, managers don't look for that experience. They look for someone with a good attitude, eager to learn.
