The Dutch were trailing Anna Flannagan’s early penalty corner goal at the breather before coming into their own in the second half with two goals in quick succession to trigger excitement into the match.
Skipper Maartje Paumen scored a customary short corner goal before Roos Drost stunningly put the Oranje brigade ahead.
Soaring in confidence after two quick strikes, the Netherlands went for broke and scored the third goal through Kitty van Male in the 52nd minute.
Maartje Paumen once again got into the goal-scoring act netting the fourth goal with another set-piece opportunity. Welten rounded off the last rites scoring the fifth goal to cap off a fine win built on a strong second half performance.
Meanwhile, hosts Argentina had to settle for the fourth position after they lost their second consecutive shootout to England 2-4 after both teams were tied 1-1 in regulation time.
Laura Unsworth gave England the lead before Argentina drew level when a cross from the right found the stick of Sally Walton en route to the English goal.
England had the last laugh in the penalty shootout.
