Transitional feature of the arc and metal droplet in the welding process with steam shielded arc is investigated by means of analysing the waveforms of welding voltage and current under different welding regimes and it is found that there are two types of arc process behavor ? " arc starting - arc blowing out - short - circuiting " and " arc - starting - short - circuiting ". under the condition of constant diameter of welding wire and its feeding speed, the arc process behavor can be changed by adjusting the inductance of welding circuit as well as the voltage of power supply. if arc process behaves as alternative process of " arc starting - arc blowing out - short - circuiting " with minimum time duration of arc blowing out and maximum frequency of short - circuit transition, the welding process will be stable with less spatter and smooth weld bead
通過分析不同焊接規范下的焊接電壓和電流的波形.研究了水蒸氣保護下電弧及熔滴過渡的特點，發現其電弧過程行為有「燃弧?熄弧?短路」和「燃弧?短路」兩種形式.在焊絲直徑和送絲速度一定的情況下，通過調節焊接迴路中的電感量和電源電壓，可以改變電弧的過程行為形式.若電弧過程呈「燃弧?熄弧?短路」交替進行，並且熄弧時間最短時，短路過渡頻率最高，在這種情況下，飛濺小，焊道成型好，焊接過程穩定 -

Switches play transmitting and cutting electrical current role during the working electrical net as a hinge, the important role will be brought into effect by the key part in switches - arc contact. if the contacts have invalidated and could not accomplished the important role during the working electrical net, switches would detonate, which result in the paralysis of whole net linked by the switches, the higher the transmitting voltage of net is, the bigger the affected area is, therefore, in order to decrease or avoid the arc eroding and invalidation during the net working, it is necessary to study the arc eroding and invalidation mechanism of contacts, sequentially make the whole net stable
可以說是電網中樞紐，而實施斷路器重要作用的核心部件就是弧觸頭，如果在動態使用中由於觸頭的失效而不能有效開斷的話，斷路器就會整機爆炸，後果就是它所連接的整個電網處于癱瘓狀態，電網的輸變電電壓越高，波及的面積越大，所以有必要對觸頭的動態燒損和失效進行詳盡的分析，減少或避免實際使用過程中的燒損和失效，從而穩定整個電網。
