发动机打火器上的“白金”触点,即接触点,过去用乙炔氧气焊接或用喷灯焊接。经研究试验后,改用接触点焊,防止了触点的氧化和提高了效率,效果很好。被焊零件为全长35毫米的M4黄铜螺钉,触点是外购的银钨合金(W90%,Ag10%)。焊剂是用银铜合金(ПCP-44 ΓOCT8190或ΠCPK-44-8TyMMT 17999-54)。为便于焊接,必须对焊机的下焊头进行改
“Platinum ” contact on the engine lighter, the contact point, in the past with acetylene oxygen welding or welding torch. After research and testing, the switch to contact welding, to prevent the contact oxidation and improve efficiency, the effect is very good. The part to be welded is a M4 brass screw with a total length of 35 mm. The contact is a purchased silver-tungsten alloy (W90%, Ag10%). The solder is made of silver-copper alloy (ПCP-44 ΓOCT8190 or ΠCPK-44-8TyMMT 17999-54). In order to facilitate the welding, welding head must be changed under the welding
