Weldon was born in Santo André, São Paulo. In his early career, he represented four clubs in quick succession: Santos Futebol Clube, Brasiliense Futebol Clube, Sport Club do Recife and Associação Atlética Ponte Preta, before moving abroad in 2004 with Al-Nassr FC of Saudi Arabia.
In the following year Weldon signed for Cruzeiro Esporte Clube: he went on to be loaned several times for the duration of his link, including twice in the French Ligue 1, with FC Sochaux-Montbéliard and Troyes AC, where the player was rarely used – only ten games and one goal in two season halves combined.
After an aborted three-year move to Botafogo de Futebol e Regatas, Weldon completed a two-year move to S.L. Benfica of Portugal (he had already played in the country the previous year, with C.F. Os Belenenses) on 21 July 2009. On 16 August he made his official debuts for the Reds, rescuing a point at home against C.S. Marítimo for the season's opener (1–1); during the club's victorious campaign he served almost exclusively as backup to Óscar Cardozo and Javier Saviola, but made the most of his minutes, namely scoring twice in a 4–2 win at Associação Naval 1º de Maio on 5 April 2010, and another brace in another away triumph (3–2 against Académica de Coimbra).
