碳纤维/不锈钢的激光焊接与组织性能研究

Study on laser welding and microstructure and properties of carbon fiber/stainless steel

为了发挥碳纤维和不锈钢各自的性能优势,对碳纤维/不锈钢进行了激光焊接处理,研究了激光功率、焊接速度和离焦量对碳纤维/不锈钢剪切性能的影响。结果表明,碳纤维/304不锈钢适宜的激光焊接工艺:激光功率为400 W、焊接速度为600 mm/min、离焦量为+10 mm,此时碳纤维/304不锈钢具有最大的剪切强度,约36.2 MPa。

To give full play to the advantages of carbon fiber and stainless steel,the carbon fiber/stainless steel was welded by laser.The effects of laser power,welding speed and defocusing amount on the shear properties of carbon fiber/stainless steel were studied.The results showed that the suitable laser welding process for carbon fiber/304 stainless steel was:laser power was 400 W,welding speed was 600 mm/min,defocusing amount is+10 mm.This is when the carbon fiber/304 stainless steel has the maximum shear strength,which is about 36.2 MPa.
