在合金焊剂层下堆焊修复“吉尔”—130曲轴本来可以采用修复吉尔—164曲轴的规范。两种曲轴都用45号钢制成,可是其轴颈尺寸(长度、直径)及其它结构元件(集垢孔等)有所不同。这对堆焊在轴颈上的金属的自行淬火过程及其金相组织的转变过程有很大影响。它的堆焊规范和工序也取决于轴颈金属质量的再分布和尺寸。采用与修复吉尔曲轴相同的加入2.0%粉状6号铬铁和2.5%粉状石墨的 AH—348A 焊剂,用
Surfacing welding under the alloy solder layer to repair “Jill” -130 crankshaft could have been used to repair Jill -164 crankshaft specifications. Both crankshafts are made of 45 steel, but their journal size (length, diameter) and other structural elements (fouling holes, etc.) are different. This has a great influence on the self-hardening process of the metal surfacing and the transformation process of its microstructure. Its surfacing specifications and procedures also depend on the re-distribution and size of the journal metal quality. AH-348A flux with 2.0% powdery ferrochromium-6 and 2.5% powdered graphite, same as Fix Jill crankshaft, was used with
