Many fabrication shops that do a lot of stainless steel tube and pipe welding are in a bit of trouble these days. The problem isn't a lack of work, of course—it's a matter of trying to handle too much work with too few resources (skilled welders). They can ask their fabricators to work harder or faster, but that goes only so far. Can a new technology help them get more output from their existing employee base?

A new grant program promotes education for the welding technician. The program focuses more on welding theory behind the various processes--and less on hands-on training.

Today several companies offer technologies that help beginning welders get that hand motion just right. None claims that the technology will replace the real thing, of course, but they do say that training in the virtual world can give students a significant leg up by the time they weld for the first time. It helps teach students what really happens between the welding arc and workpiece, why certain hand motions produce good beads while other motions don't. And it also may help introduce welding to students who wouldn't have given the trade a second thought.
A new resource tool takes away the guesswork and the apprehension when welding titanium: The American Welding Society (AWS) D1.9/D1.9M Structural Welding Code—Titanium. Released in July 2007, the code goes beyond the limitations of previous documents by providing the information required to engineer a structural titanium product from start to finish.

Think you want to learn TIG welding, also known as GTAW? To master the craft and avoid injury, it's imperative that you receive proper instruction. TIG is not a process that lends itself to self-teaching. This overview compares TIG with other welding processes and outlines some important steps of the process.

Welding workpieces with circular components can leave welders spinning, literally. By keeping three considerations in mind, welders can stop spinning and start welding.

Who can inspire a young person to pursue a welding career better than a peer who welds? How about a peer who also is a stock car driver? Racer and welder Brennan Palmiter has teamed up with the Fabricators & Manufacturers Association (FMA) Foundation and Practical Welding Today® magazine to introduce more young people to manufacturing careers.

Welding around any kind of circular piece can be a challenge. To make a fillet weld in the horizontal position, you will have to maneuver around the workbench, maintaining a constant arc if you wish to make a continuous weld. This type of work may be acceptable if you need only a few pieces, but can become tedious on production runs. One solution is to rotate the workpiece past the welding arc with a rotating welding positioner, such as a small- to medium-size benchtop machine.

Arming yourself with basic information about flux-cored wires can help you decide if these consumables are right for your welding application. Available in gas-shielded and self-shielded, flux-cored wires require less skill to use than other filler metals and commonly are used for general fabrication, pressure vessels, petrochemical piping, and heavy-equipment manufacturing
