On Jan. 30, 2026, U.S. Army Corps of Engineers - Far East District’s Mr. Shin, Chang, Engineering Technician for the Quality Assurance Branch (QAB) led a welder and brazer qualification tests for a $43 million satellite communication building at Camp Humphreys, South Korea. Candidates welded thick pipes using Gas Tungsten Arc Welding (GTAW), a process that joins metal with a hot tungsten tip and gas to make a clean, precise weld and brazed 3 inch copper pipes in horizontal and vertical uphill positions, showing they could work in any orientation. The brazing required heating the pipes to about 1,200 degrees Fahrenheit. After visual inspection, samples were tested by bending, X-ray, cutting and peeling to confirm joint strength, qualifying the workers, and certifying the welding and brazing processes. Additionally, to recertify for individuals who failed to meet acceptable performance standards or who demonstrated an inability to continue the same welding or brazing process for more than six months.
