过去铝芯线焊铜鼻子多用A型焊药焊的,施工麻烦,质量不保征,工效低。最近,我们参考了一些有关“低温反应腊焊”的资料,并在宝安氮肥厂对铝芯线焊铜鼻子进行多次试验,效果良好,过去用A型焊药焊一个多股铝芯线铜鼻子需用一个多小时,现在用低温反应腊焊,同样的多股铝芯线铜鼻子,一小时可焊几个,而且质量比过去好。该厂经过一段时间运行证明,凡采用此方法焊接的接头。从未有发热和其他异常现象发生。低温反应腊焊在广州氮肥厂早已应用(焊药外购),反映亦称很好。现把宝安氮肥厂的经验介绍如下: (一) 焊接方法 1.将铝芯线头绝缘剥开(不必另加处理)。
The past aluminum core wire with more A-type welding flux nose welding, construction trouble, the quality does not guarantee levy, low efficiency. Recently, we have referred to a number of “low-temperature reactive wax welding,” the information, and Baoan nitrogen fertilizer plant aluminum core wire copper nose for many tests, the effect is good, the past with A-type welding flux welding a multi-strand aluminum copper wire Noses need more than an hour, now low-temperature reaction with the Lantian, the same multi-strand aluminum core copper nose, an hour welding a few, and the quality is better than in the past. After a period of operation of the plant to prove that where the use of this method of welding joints. No fever or other abnormalities have ever occurred. Low-temperature reaction wax welding in Guangzhou nitrogen fertilizer plant has long been used (welding drug outsourcing), also known as very good reflection. The Baoan nitrogen fertilizer plant now experience are as follows: (A) welding method 1. Aluminum core wire insulation stripped (without additional treatment).
