对于管道或管尺寸4英寸（10.2mm）OD和下方，条带进料到一组成形辊，该成形辊由水平和垂直辊组成，使得从平坦的条带逐渐逐渐逐渐进入管道，然后将其逐渐逐渐被允许通过焊接电极。电极是连接到旋转变压器组件的次级的铜盘。铜盘电极在接缝的每一侧接触，温度升高到焊接点。通过切割工具在管离开电极的情况下通过切割工具去除外部闪光灯，通过空气锤或通过在管冷却后通过焊接管通过心轴来除去闪光。这称为电阻焊接或ERW管/管道。

钢管制造商和出口大量of ERW Galvanized Steel Tubes & Steel Pipes. For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks connected to the secondary of a revolving transformer assembly. The copper disk electrodes make contact on each side of the seam and temperature is raised to the welding point.

Outside flash is removed by a cutting tool as the tube leaves the electrodes, inside flash is removed either by an air hammer or by passing a mandnel through the welded tube after the tube has been cooled. This is termed as Electric Resistance Welded orERWtube/pipe.
