摘要

为了比较光纤激光及CO2激光焊接特性,采用2 kW 光纤激光器及2.4 kW CO2激光器对590 MPa 高强钢板进行焊接试验,通过改变离焦量及焊接速度等焊接参数,研究了两种焊接方法的熔深变化情况。结果表明,当焊接速度和输出功率相同时,光纤激光与CO2激光焊接相比可获得更大的熔深;在负离焦条件下,离焦量在焦深以内时可使熔深增大;功率一定时,熔深随着焊接速度的增加而减小,但是CO2激光焊接的熔深减小比率大于光纤激光焊接。

Abstract

In order to compare the welding characteristics of fiber laser and CO2 laser, a 2 kW fiber laser and a 2.4 kW CO2 laser are used to weld 590 MPa high strength steel plates. By changing the defocusing distance and the welding speed, the penetration depth is investigated. The results show that with the same welding speed and the same output power, the fiber laser welding gets more penetration depth compared with CO2 laser welding. With a negative defocusing distance, the penetration depth becomes greater when the defocusing distance is within the range of focal depth; the penetration depth increases with the decrease of welding speed when the power is constant, and the penetration depth using the CO2 laser welding decreases faster with the increase of welding speed than fiber laser welding.
