The figure shows the seam cross-sections, penetration ratio, and heat input with different EP/EN ratios. Intermetallic trails are observed near the Ti-6Al-4V side owing to the flflow of the melting pool. The heat input trend is consistent with the penetration ratio to maintain a con-stant stick-out.
