I apologise if this has been asked before but I don't have a computer and my iPad don't display a search button.
I have recently got into d&d with my friends, we are all new to it and loving it. But I feel that we are doing the save throws wrong. We understand the mechanics behind them, but what we don't know is when exactly you make a saving throw, is it after every hit or only at certain times? Some help on this would be appreciated 
Thanks,
Spee,
You make a saving throw when an effect calls for you to make one. Many spells will require a subject to make a saving throw to avoid or reduce its effect, for example. When triggered, most traps will also require their victims to make saving throws to dodge or withstand their effects.

Page 62 of the basic rules PDF talk about saving throws.
Saving throws are generally used to avoid damage from specific (but not all) spells, traps and trap-like effects (like falling down if moving full speed through an area someone has scattered ball bearings to avoid falling).
You generally make either an attack, or a saving throw.
Weapons generally use attacks, spells generally use a saving throws, but not always.
Completely answered my question thanks so much guys!!
