Summary: Effect of laser welding parameters on weld properties are studied in fillet and lap configurations. The results indicate the interlateral relationship between laser process parameters and responses (weld fillet size, penetration depth, concavity size, liquation density and HAZ dimensions) and fundamental differences between the fillet and lap laser welding.
