When a well-known architect was hired to design student housing complex at California State University San Marcos (CSUSM), she teamed up with Lisa Schirmer and a fabricator to develop a fence-and-gate system that would look good, invoke local flora, and provide security for the residents. The result is part fence, part art.

A welder tackling gas tungsten arc welding of thin aluminum for the first time might find it more difficult, but in reality, it's just different from the gas metal arc welding that he or she originally learned. Following these guidelines can help the welder make a smooth transition into thin aluminum welding.

If you are considering making the change to self-shielded FCAW from SMAW, remember to consider the proactive measures you’ll need to take to make that transition successful. It’s important to have a solid understanding of the characteristics and operating requirements of the new filler metal being used to weld successfully with it.

An automobile enthusiast since he has a youngster, Ariel Banco started developing custom-made air intakes after he graduated from college. Eventually he had such a backlog that he quit his professional career to become a full-time fabricator, making air intakes for automobiles, motorcycles, and occasionally airplanes and personal watercraft.
When welding process pipe, welders need to determine which wires can provide the most appropriate results for every weld pass—root, fill, and cap—and be certain that they are selecting the highest-quality filler metal.

Not everyone involved in welding wields a torch. Welders’ helpers play integral parts in welding projects and sometimes command a higher salary than the welder.

Gas metal arc welding is an effective method for joining thin-gauge materials-- from 24-gauge to 0.1875-in. carbon steel and 18-gauge to 0.1875-in. stainless steel. But extra attention should be paid to the equipment and the welding technique to minimize burn-through and distortion.
Gas tungsten arc welding, a joining process developed decades ago, has been improved by many technology developments over the years, but the essentials are unchanged: It uses an electric arc between a nonconsumable tungsten electrode and the workpiece to produce a weld pool, and it uses a shielding gas. Experiments with brushing on or pasting on mixed metal oxide slurries have shown how this decades-old process can improve dramatically in penetration and speed.
