如果发动机上的油管(紫铜管、铁管)断了,而您手头又没有焊接设备,怎么办?遇此情况,您不妨采用下述方法:先找一些焊料,如焊粉(硼砂)、φ5毫米以下的黄铜丝30～50毫米、拳头大小的焦炭一块,然后再用随车携带的喷灯作焊枪对油管施焊。施焊时,将焦炭砸成碎片,把需焊接的油管放在焦炭堆上,用喷灯对油管和焦灰同时加温(没有焦炭时,直接加热管子),当油管已呈赤色时,把黄铜丝也加热一下,然后迅速沾上焊粉,并立即放在油管的焊缝上,待焊丝(即黄铜丝)熔化并充满焊缝时止。移开喷灯,稍待冷却即可。如果被焊件是紫铜管并需作弯时,可先趁热放入冷水中淬火(因紫铜管越淬火越软),淬火后就可随意作弯了。
What should I do if the tubing (copper tube, iron tube) on the engine is broken and you have no welding equipment on hand? In this case, you may wish to use the following methods: Find some solder, such as solder powder (borax) φ5 mm below the brass wire 30 to 50 mm, the size of a fist piece of coke, and then with the car carrying torches for the welding torch on the tubing. When welding, the coke smashed into pieces, the tubing to be welded on the coke heap, with a torch on the tubing and coke heating at the same time (no coke, the direct heating of the pipe), when the tubing has been red, the yellow The copper wire is also heated for a moment, then quickly dipped into the solder powder and placed immediately on the tubing seams until the welding wire (brass wire) melts and fills the weld. Remove the torch and allow it to cool slightly. If the piece to be welded is a red copper tube and needs to be bent, the first hot into the cold water quenching (the more quenching the more soft copper), after quenching can be free to bend.
