高速钨惰性气体（t.i.g.）ARC已经表明需要实验来确定它们的熔化性能。为了实现这一点，一个新的设备已经建成，其中的工件是相当厚的，而不是使用薄的工件作为工件的早期测试。该装置还具有量热能力，其允许确定总热输入的大小。数据描述的变化的焊缝熔深，宽度和横截面在很宽的范围内的电弧条件（电流，速度，尖端角度，电弧间隙）已被确定。此外，有趣的观察已经作出了关于在某些电弧条件下的热输入的变化分布。
Previous work with high-speed tungsten-inert-gas (t.i.g.) arcs has shown the need for experiments to determine their melting performance. To achieve this, a new apparatus has been built in which the workpiece is of substantial thickness, rather than the earlier tests which used thin shims as the workpiece. The apparatus also has a calorimetric capability, which allows the magnitude of the total heat input to be determined. Data describing the variation of the weld penetration, width and cross-section over a wide range of arcing conditions (current, speed, tip angle, arc gap) have been determined. Additionally, interesting observations have been made concerning the changing distribution of heat input under certain arcing conditions.
