我們根据苏联建筑業先进生产者代表团团員克馬洛夫所介紹的焊鉗結構,試制了一种構造更加簡單的电弧焊钳。实际应用証明,这种焊钳有这些优点:更换焊条便利、使用輕便、安全。这种焊钳主要有三个部分(請看附圖)。上部分用φ8×70公厘的圓鋼弯成,一端焊在角鋼腹內,一端要比角鋼凸出3公厘。下部分是用廢鉄板做成的角鋼(如果有紫銅
According to the structure of the welding torch introduced by Kemalov, member of the delegation of advanced producers in the Soviet construction industry, we tried to create a simpler arc welding torch. Practical application shows that these welding tongs have these advantages: easy to replace the electrode, the use of light, safe. There are three main parts for this type of welding gun (see the photo). The upper part is made of a round steel with a diameter of φ8 × 70 mm. One end is welded to the inside of the angle steel and the other end protrudes 3 mm more than the angle steel. The lower part is made of scrap iron angle (if there is copper
