中文摘要:R5级系泊链钢是一种对焊接工艺要求较高的材料,为保证系泊链产品力学性能合格,通过大量试验对其闪光焊接参数进行了研究。结果表明,烧化量、顶锻量、焊接速度和二次空载电压是影响焊接接头质量的重要参数;要保证产品性能,必须将闪光焊接参数控制在一个非常窄的范围内,并获得了其最优化的焊接工艺。
英文摘要: The effects of flash butt welding parameters on properties of products were explored for Grade R5 mooring chain. It is shown that the change of the flashing length, upsetting length, flashing speed and no-load secondary voltage which are the parameters of the flash butt welding have a significant influence on quality of weld joint. Through this work, flash butt welding condition of the ?准84 mm R5 mooring chain for the offshore structure was presented.
