Coking in welding
WebThe invention provides a coking tower transition portion and a processing and welding method. The transition portion is divided into N portions, wherein N is more than 2; vertical notches are arranged at two ends of a finished product of each transition portion, and the section of each notch is rectangular; the width of each notch is 1/2 of the width of a U … WebDepending on the severity and duration of the arc, each time an arc ignites, contact erosion occurs. This erosion causes a loss of contact material which will result in one of two conditions. Figure 1. Condition #1. Condition #1 is where so much material is lost from the contacts that they fail to electrically close the load circuit.
