摘要:
采用水平对焊的方式实现了孕镶金刚石锯片刀头与钢基间的高强度激光焊接,研究了激光焊接工艺参数对金刚石锯片焊接质量的影响,激光焊接工艺参数包括:光束模式,激光功率,焊接速度,离焦量,等离子体控制和光束偏离量。试验结果表明,光束模式,激光功率,焊接速度,离焦量,等离子体控制能显著影响激光焊接深度;光束偏离量则会影响焊缝中的气孔数量。
Abstract:
The diamond impregnated segments and the steel core were laser welded in a horizontal arrangement to achieve very high bond strength between them. A parametric investigation was conducted to evaluate the effect of several essential variables on high power laser beam Welding, which include beam mode, power level, weld speed, focal Point position, Plasma Suppression and beam alignment.
The results showed that beam mode, power level, weld speed, Plasma suppression along with focal point position are the Primary parameters, which can influence the depth of penetration of laser welding. Beam alignment can greatly affect the amount of pores in the welded seam.
