摘要:
以HQ130钢为参照对象,在22SiMn2钢用于装载机铲斗焊接的接头时,研究不同匹配与不同工艺参数条件下获得的焊接接头的抗拉、抗弯、抗冲击、抗裂性等力学性能.研究结果表明,22SiMn2钢采用H08Mn2SiA填充材料,Ar+CO2气体保护焊,通过合理的工艺选择,可以得到强度,韧性都能符合工程要求的焊接接头,并且接头有一定的塑性储备,强度等级达到HQ130钢的接头同等水平,具有冷裂倾向.
Abstract:
The mechanical properties such as tensile resistance,bending resistance,impact resistance and crack resistance of the welding joints which are obtained under the condition of different matches and different process parameters are investigated,when 22SiMn2 steel is used in the welding joints of a loader bucket replacing HQ130 steel.The investigation results have shown that the welding joints have some certain potential plasticity,an equivalent strength grade of HQ130 steel,and a tendency of cold cracking,the strength and toughness of which can meet the engineering requirements,if H08Mn2SiA is used as the filling material for 22SiMn2 steel,Ar+CO2 gas shielded welding is used,and reasonable process is selected.
