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.

Four of 1,000 welders lose their lives each year, and many more are seriously injured because they fail to follow safe welding practices. Welding hobbyists who follow the examples set on television are particularly susceptible to injury. In this article, Marty Rice reflects on moments in his welding career that illustrate the importance of welding safety.
Ultrasonic metal welding, around since the 1950s, has proven itself useful in a variety of industries where joining applications involve thermally conductive materials. While the process does have its disadvantages—joint configurations, thickness limitations, and difficulty welding high-strength materials, to name a few—ultrasonic metal welding has a bright future with the rising popularity of lightweight materials in the automotive and aerospace industries. This overview of the process will outline the principles of ultrasonic metal welding, describe the key weld process parameters, and note a number of process applications.
