摘要
对Cr13Mo1Si1V1钢进行激光焊接,研究脉冲能量和脉冲宽度对焊缝横截面尺寸的影响规律。结果表明,当激光脉冲能量增大时,焊缝熔宽明显增大,熔深和下凹深度稍有增加,焊缝深宽比减小;当脉冲增度增加时,熔深有所增加,但在其他工艺条件不变的情况下,脉冲宽度的增加有一个临界值,脉冲宽度增至临界值后,熔深反而变浅。
The pulse energy and the pulse width are main technical parameters of pulse laser welding process.They make a great imquence on the weld appearance and size.The welded joints of Crl3MolSilV1 steel are made by laser welding process.Researched on the effect of the pulse energy and the pulse width for weld cross section size.The results showed that, when the laser pulse energy increased,the weld width increased obviously,the penetration and the concave depth increased slightly,weld depth to width ratio decreases.When the pulse width increased, depth of penetration increased ,but in other conditions remain unchanged, the pulse width increases has a critical value, the pulse width to the critical value, the penetration became lighter.
