前言 我所研试成功的“ZH”焊接方法,是一种操作简便,成品合格率高。成本低,机械强度大,对环境无污染的钎焊万法。已大批量进行生产加工,具有推广的价值。已向中国专利局申请了专利。 此种焊法与传统的“电炉闪光焊”和“氧+乙炔喷焊合金”及“等离子堆焊合金”的质量相比均有独到之处,其优点如下: ①保证焊接处的金相组织为冶金结合。 ②精加工后端面无气孔。 ③不需使用价格昂贵,且对皮肤有污染及过敏反映的着色探伤,更不需在暗室中进行萤光探伤。 ④仅需采用随机抽样按样本大小和规定的水平作超声波无损擦伤。
Preface The “ZH” welding method that I have successfully researched is a kind of simple operation and high qualified rate of finished products. Low cost, high mechanical strength, pollution-free brazing method. Has a large number of production and processing, with the promotion of value. Has applied for a patent to China Patent Office. This welding method with the traditional “flash furnace welding” and “oxygen + acetylene spray welding alloy” and “plasma surfacing alloy” compared to the quality of the quality of the original, the following advantages: ① to ensure the welding of the microstructure For metallurgical bonding. ② Finished non-porous end face. ③ do not need to use expensive, and the skin is contaminated and allergic reaction to the coloring test, but do not need fluorescent test in the darkroom. ④ Only a random sample according to the size of the sample and the required level for ultrasonic nondestructive abrasion.
