1g position in the 1g welding position the pipe is in the horizontal position and can be rotated along the horizontal x axis. Sheet fillet welds are divided into. Different welding test positions based on aws and iso qualification based on test plates and pipes. Autoplay when autoplay is enabled a suggested video will automatically play next.
