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.

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.

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.

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.
