摘要
引进产品980S装载机铲斗采用国产新钢种HQ130与QJ63焊接而成.介绍了CO_2焊、手弧焊条件下,HQ130-QJ63接头的力学性能、抗裂性能试验结果及金相组织分析.试验结果表明,采用H08Mn2SiA焊丝在不预热条件下进行Ar+CO_2焊,接头强度达到美国CAT公司样机同等水平.
The loading shovel is made by welding from domestic steels HQ130 and QJ63 to match imported 980S loading machine. The mechanical properties, the cracking resistance and metallography analysis arc introduced for HQ130- QJ63 sted joint welded with CO2 welding, Ar + CO2 welding and manual arc welding methods. The results show that the pint strength can reach the same level as QJ63 steel and welding quality fulfill same status of American CAT Co. model machine as Ar+ CO2 welding with H08Mn2SiA wire welded under cold state procedure is used.
