Abstract
This paper compares the weld seam formation of large thickness electroslag strip overlay welding by using EQNiCr-3 and EQNiCrFe-7A,and analyzes the reasons why EQNiCrFe-7A is not suitable for large thickness electroslag strip overlay welding and the key technologies that affect the quality of overlay welding.The study has determined reasonable process parameters of EQNiCr-3 large-thickness electroslag strip overlay welding and checked property of the overlay welding layer.
