Abstract : with the aids of computer ' s hardware, executive mechanism of weld arc length automatic controller of all - position pipe welder and additional software, an automatic system for arc striking has been developed, in which touch - starting method using tiny current is introduced. utilizing this method, the ablation ratio of tungsten electrode and tungsten inclusion ratio of welded seam is far smaller than normal touch - starting method. and the successful ratio of arc striking is high
文摘:用全位置自動焊管機弧長自動控制系統的計算機硬體和執行機構，僅增加部分程序，設計了採用小電流接觸引弧法的自動引弧系統，鎢極燒損和焊縫夾鎢遠小於普通的接觸引弧方式，引弧成功率很高。 -
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 -
