A special design of narrow gap SAW machine is developed in order to weld straight and circular joints at flatposition.
研制了适合水平直焊缝和水平圆形焊缝的窄间隙埋弧焊专用焊机。

NC machine is used to ensure that longitudinal and circular weldings are produced at a constant speed and the welding point is always in flatposition.
数控主机用于保证箱底纵、环焊缝焊速恒定并使焊接点始终处于平焊位置。
