Welding experiments of DP980 high strength steel plate with fiber laser have been processed. The influence of welding parameters on welding quality has been investigated. As well as microstructure and mechanical character of welding seam has been analyzed. It is showed that the joint appearance of DP980 high strength steel welded with fiber laser has good performance and the mechanics property is good. The microstructure of weld bead is columnar crystals; Heat-affected zone is narrow and the grain grows with little size; the measured micro-hardness values of the sample decrease smoothly from weld center to base metal.
