The Belfast feather defeated England’s Karriss Artingstal in the opening session of the tournament in Sofia.
Artingsal, of the Royal Air Force, put up a good fight in their Round of 32 encounter and looks one to watch but was beaten by Walsh in a competitive bout with started slow and finished fast.
It was quick return to the ring for Walsh who won Commonwealth silver in Australia less than two months ago and the extremely dediated Monkstown fighter is back looking for a third successive medal at a major championships following EU bantamweight gold last year and her recent Gold Coast silver.
In an extremely cagey opener, Artingstal stood off and looked to counter – with Walsh doing much the same – before a very strong final thirty from the Irishwoman which saw her stamp her authority on the bout, scoring with a nice check hook before surging forward with a number of flurries.
A more open second saw the English fighter begin to come forward. Artingstal did have some pockets of success but Walsh was proving elusive and her sweeping backhand right scored well to both body and head.
The slightly longer Artingstal came out firing at the start of the third, her best round, and Walsh granted her war wish, going toe-to-toe and sinking in some heavy-looking body shots mixed with periods of smart back-foot boxing
Going to the cards Walsh was awarded a fully-deserved 5-0 unanimous decision and now proceeds to the Last 16 where she will face Alessia Mesiano of Italy.
Kelly Harrington and Grainne Walsh are next up for Ireland, fighting in the last 16 on Thursday.
Dublin lightweight Harrington faces Czechian Katerina Humlova while Offaly welter Walsh boxes Russian former underage star Yaroslava Yakushina.
All three Irish fighters are now just one win away from securing a spot at the 2019 European Games in Belarus. Should they be defeated in the Last 16 theystill have a shot at qualification for Minsk should their defeator progress to the final here.
