The function of soldering flux is (1) to clear oxide on metal surfaces, 92 to reduce tension on the solder surface so as to enhance the diffusion capacity.

助焊剂的功能为（1）清除金属表面氧化物，（2）降低焊锡表面张力，增加其扩散能力。

Engine work, if crude oil filter was a serious blockage of impurities, or due to low temperatures when the oil viscosity changes, the main oil缺油Road will be the engine will lose lubrication, this is very dangerous, especially in the main bearings and connecting rod bearings, if there is no oil will be burned, bearing alloy heat due to friction loss and even journal welded together, eventually forcing the engine to stop working.

发动机工作时，若机油粗滤器被杂质严重淤塞，或者由于气温低而机油粘度变大时，主油道就会缺油，发动机就会失去润滑，这是很危险的，特别是主轴承和连杆轴承，如果没有润滑油会烧坏，轴承合金会因摩擦发热而流失，甚至和轴颈熔焊在一起，最终迫使发动机停止工作。

The hidden welding of box frame member's dummy plate should use Electro-slag Welding.

箱型构件中隔板的隐蔽焊接，需采用电渣焊焊接。
