Arc Welder

The welder’s helper

August 5, 2013 | By Vicki Bell

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.

Choose wisely when welding thin sheet

August 1, 2013 | By Jerry Mathison

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.

Improving GTAW for producers, fabricators

July 19, 2013 | By Dr. Yehuda Baskin, Dr. Ian Harris

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.

Underwater aluminum GMAW

May 3, 2013

The U.S. Navy has been searching for new weld-repair methods on its aluminum-hulled ships beyond dry docking, which is impractical and costly. Phoenix Intl., an underwater services company that has held the Navy’s Diving Services contract for the past 15 years, may have found one: underwater aluminum GMAW in a hyperbaric chamber.

New guideline reduces manganese exposure limit dramatically -

New guideline reduces manganese exposure limit dramatically

April 19, 2013 | By Kimberly Gates, Scott Larson

Chronic exposure to manganese oxide fumes, which occur when manganese metal is heated and reacts with oxygen, can lead to damage to the central nervous system. Welders are especially susceptible to this disease, called maganism by the National Institutes of Health, because manganese is found in many welding rods and filler metals to promote hardness. The American Conference of Governmental Industrial Hygienists recently issued guidance that dramatically reduced suggested threshold limit values. Because many metal fabricators use this guidance to manage worker exposure, they now are having to rethink how they approach personal protective equipment.

3 ways to boost submerged arc welding performance

April 19, 2013 | By Steve Massey

Submerged arc welding is known as a process that can result in high welding speeds and deposition rates. However, in today's manufacturing reality, engineers are always looking to boost productivity—even for already productive processes. Fortunately, companies have three common approaches to consider to increase the performance of their submerged arc welding systems.

The broader implications of modular weld fixturing

April 17, 2013 | By Pam Farley

A shop is only as productive as its constraint process—that is, its bottleneck. All that adaptability in upstream processes may not make a part cost less if it takes days or weeks to build a new weld fixture. A modular approach to weld fixturing can help.
