焊工(焊接操作者)及定位焊的合格试验,取决于试验者个人的能力,即在试验中是否能按照焊接的工艺、材料、流程,焊接出验收合格的焊缝。图1所示是管道角焊缝不同的试验位置,具体说明如下:图1A是一种用于管道连接的环形角焊缝试验位置,此时管道轴线与水平成近似45°,管道作轴线旋 Welder (welding operator) and positioning welding qualified test, depending on the test individual ability, that is, in accordance with the test welding process, materials, processes, welding out qualified welding seam. Figure 1 shows the different test locations for fillet welds in pipelines, as specified below: Figure 1A is a test location for a toroidal fillet weld for pipe connections where the pipe axis is approximately 45 ° from horizontal and the pipe is axis-swirled
