The arc welding technology area focuses on the most commonly used arc welding processes, mainly GMAW/MIG, GTAW/TIG, SMAW/stick, and plasma. The articles and press releases cover processes and power sources, plus all of the related items—electrodes and wire, wire feeders, fixtures, manipulators, positioners, and power sources. If you need information on personal protective gear, ventilation systems, and safety practices for welders, see our Safety coverage area.

"Titanium need not be all that hard to weld!"The American Welding Society (AWS)1said it, and I agree. Well-done titanium welds look like frozen mercury: shiny and reflective. A couple of basic factors make titanium different from other metals. These unique characteristics, and a lack of...

The Santa Ysabel Ranch entry arch and gates, Paso Robles, Calif.Creating an entry gate for a new housing development doesn't sound like such a tough assignment until you toss in historical references as design constraints. Using the lore and symbolism of the Chumash Indian tribe that once settled...

The demand for flux cored arc welding (FCAW) has grown significantly over the past 10 years. Manufacturers who weld carbon, stainless, low-alloy, and high-alloy steel are turning to this process primarily because:It has a high deposition rate.It can be used to weld in all positions with designated...

The Jos. L. Meyer GmbH shipyard in Papenburg, Germany, built its first wooden sailing ship in 1795. Today the six-generation, family-owned shipbuilding company designs and builds large metal cruise liners, gas tankers, and ferryboats. These floating behemoths can be as large as 162.5 by 975 feet (50 by 300 meters), and 162.5 ft. (50 m) high.

Mixing oxygen with fuel gases for brazing, cutting, heating, and welding metal has been around since the early 1900s. Oxyfuel processes have remained in use over the years despite the introduction of other metal fabrication processes, such as arc welding, plasma cutting, and laser materials processing. Finding the most economical method for supplying oxyfuel gases requires a basic understanding of the process.

Two years after the terrorist attacks of Sept. 11, 2001, most people's lives have returned to some degree of normalcy, but what happened on that day will never be forgotten. For one metal sculptor, remembering has become a crusade to create from steel salvaged from the World Trade Center a lasting memorial of the tragic event and the resilience of the human spirit.

The metal fabrication industry has used compressed gases for more than one hundred years. Oxy-fuel cutting and welding have existed since the beginning of the 20th century. The more automatic welding processes, such as gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW), began as early as 1920.

One of the stupidest things I ever did as a parent was to buy my son a book about kyusho-waza (pressure point attack) written by master martial artist, George A. Dillman. I then became the recipient of painful ambushes in the hall, kitchen, and even driving down the road in my truck. I...

Businesses feel a constant pressure to gain an advantage and control their processes better. However, the decision to embrace new technology often leaves them feeling vulnerable. In the realm of hand-held metal cutting operations, one such decision is choosing between traditional technology and an inverter-based plasma cutting system.

Watching the sparks fly as his dad welded a temperamental posthole digger mesmerized Derek Arnold. "I found the immediacy of something so permanent absolutely fascinating," he said. "I knew I wanted to weld."A hands-on welding education on the family farm drove Arnold to take his skills and creativity to the next level. In 1993 he graduated from the Maryland Institute College of Art in Baltimore. "I've been welding regularly since my freshman sculpture class," he said.
