Although oil extraction around the world has grown by 50 percent in the last 30 years, it was basically flat in North America until 2008. Higher oil prices have made tar sands oil economically viable, and new extraction techniques have been a boon to U.S. producers. Interviews with a variety of vendors in the forming and fabricating industry reveal the many trends that are driving changes in the equipment and supplies used in the petroleum business.
Arc performance and electrical efficiency have driven various advances in inverter-based welding power sources. These improvements have led to present-day digital welding systems that allow for repeatable, high-precision, low-spatter welds on a variety of materials.
