Welling showed plenty of heart and desire but ultimately a lack of firepower in the final third saw Dover win the Kent Senior Cup for the first time in 26 years at The Gallagher Stadium Maidstone.
It was a much changed line up for Welling with six changes made from the lacklustre defeat at Bath on Saturday.
As you would expect Dover started brightly and one of a number of ex Wings players on show Moses Emmanuel shot straight at Chris Lewington when well placed before Pinnock hit an effort from range that was always rising and went high over the bar.
Having survived the opening exchanges Welling settled into the game and ventured forward themselves.
A smart ball from the lively Tom Richards played in Ali Fuseini who hit a low shot that was heading in but Mitch Walker another former Welling man, made a smart save.
Richards was in the thick of all the Welling play and he was was in played in behind by Dan Walker, before cutting into the area but hitting his effort straight at namesake Mitch Walker.
Welling were enjoying a good spell of possession as Fuseini played a great pass to Dan Walker but he dragged his shot wide.
Sam Hatton then missed a glorious chance having made space for the shot he twisted and turned before dragging an effort just wide that looked to be creeping in.
As the game drew towards half time Dover almost went ahead Sam Magri heading the ball across the goal when he was well placed to nod home as Welling scrambled the ball clear.
Into the 2nd half and Welling should have gone ahead within 2 minutes. Alex Cathline did well to power his way into the box before choosing to shoot at goal when a pull back for the waiting Harry Crawford would have surely resulted in a goal.
This miss proved costly as in the 54th minute Ross Lafayette showed the quality needed to win football matches. The former Wings fans favourite picked the ball up 25 yards from goal with his back to goal he turned, before curling an effort into the top corner, a goal good enough to grace any cup final.
The Wings never let their heads dropped and actually had a lot of the ball without threatening too often.
They did have the odd chance as Harry Crawford saw a rifled shot saved by Mitch Walker before Dan Walker had his shot saved by the legs of Walker as Welling tried to push for an equaliser.
Dover sub Peter Skapetis could have scored with an audacious bicycle kick but his effort went just wide.
Welling sub Jamie Slabber almost scored with his first touch of the ball but he put a header just wide of the post. But Dover won the final when in the 86th minute Aswad Thomas got on the end of a Joe Healy cross to head pass Lewington at the back post.
The Wings now face a summer of rebuilding as they prepare a new squad for the 2017/18 season.
Welling: Lewington, Richards, Johnson (Joseph-Dubois 71mins), Fish (Slabber 82mins), Waldren, Hayles, Fuseini, Hatton, Cathline, Crawford, Walker. Subs not used: Leacock, Francis, Agu.
