高功率CO2激光深穿透焊接的研究
Study on laser deep penetration welding of metallic materials
摘要
本文采用3～5kW(低阶模3～4kW)高功率CO_2激光束对18CrMnTi低合金钢进行了深穿透焊接的研究,焊缝深宽比接近2,焊接穿透深度达到5.5mm以上,对影响激光深穿透焊接效果的各种焊接工艺参数进行了研究。找到克服激光焊缝区缺陷的一些有效措施。
Abstract
Experimental results on the welding of low alloying steel (18CrMnTi) and 45 steel with 3-5kW CO2 laser are discussed. The depth/width ratio being about 2, the maxium penetration depth is about 5.5mm. Various technological parameters influencing the effect of laser deep penetration are studied and some effective measures for overcoming the defect (crack, gas hole) of aser deep penetration welding have been found.
