As plasma, welding arc has well electric character. exterior magnetic field can affect shape and movement of welding arc. and the welding bead and drops transfer can also be changed to improve the welding process and advanced the productivity
電弧作為一種等離子體,具有優良的導電性,用外部磁場可以改變電弧的形態和運動特性,影響焊縫熔池和熔滴過渡形式,大大改善焊接工藝,提高焊接生產效率。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
