中文拼音 [hànjiēhuílù]
焊接迴路
英文
welding circuit-
The main loop of the welder uses a thyratron transistor non - contact switch circuit, quick and reliable close time, accurate timing of welding, high precision of welding, good repeatability, bring a high quality welding
焊機主迴路採用晶閘管無觸點開關電路，關斷時間快、可靠，焊接定時精確，焊接精度高，重復性好，可實現高品質焊接。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Using the digital technology improves the performance traditional thyristor welding machine, according to the characters of the double inverse star from rectifier circuit, set the parameters with micro - controller accurately, design the dependable trigger circuit, lead the feedback of voltage for the operation program, so the voltage of main circuit be carried out very steadily
摘要利用數字控制技術對傳統晶閘管焊接電源進行改進，根據雙反星型晶閘管整流電路的特點，採用單片機進行精確設定，設計了高可靠性觸發迴路，結合電壓反饋進行程序運算控制，實現了主電路輸出電壓的精確調整和可靠運行。Found in 1990 by chairman johannes rehm, the company has since become a leading supplier of manufacturing technology for the electronics industry. rehm is setting standards in the development of design and fabrication of customer - specific applications for economic printed circuit board manufacturing, and the development of insert gas inflow soldering systems
