  1. But there are some technical difficults for the welding of aluminium alloy such as some broken bits being easily found, a large welding distortion can happen easily, hard to distinguish the difference between the solid metal and liquid metal colour, hard to control the temperature, a lot of air holes can be seen in the welding line and so on

    但是鋁合金熔化技術難點在於:時易引起夾渣,變形大,金屬固態和液態色澤不容易區別,操作時控制溫度困難,容易產生氣孔等等。如果工作不是很好,檢測氣孔往往超標。
  2. At last, an experiential power supply was made, and a series of experiments is done. a lot of high - frequency pulse current was superposed on dcen current, modulated the welding current waveform we required and optimized the energy distribution, which satisfied the basic requirement of cathode cleaning

    最後製作了一臺實驗電源,並進行了一系列電弧實驗,通過在變極性電源電流dcen基礎上疊加一系列脈沖電流,調制出所需電流波形,實現輸出能量最優分配,在滿足陰極提下,最大限度地提高效率。
