He made a third attempt at a British title on 4 May 2018, against Tommy Langford at the Walsall Town Hall. Welborn won via split decision (SD) over twelve rounds to capture Langford's British middleweight title. Two judges scored the bout 114–113 to Welborn, while the third scored it 115–113 in favour of Langford. He defended his British middleweight title on 8 September 2018 in a rematch against Tommy Langford at Arena Birmingham.

On 1 December 2018, he faced undefeated unified light-middleweight champion Jarrett Hurd for the WBA (Super), IBF, and IBO titles at the Staples Center in Los Angeles, California, losing via fourth-round KO. Welborn started the fight as the aggressor, pressuring the champion on the front foot throughout the first round which saw Hurd being defensive, taking clean punches and a solid right hand. The second round saw Hurd pick up the pace, with Welborn still out working the champion. The third round was much of the same, with Welborn backing Hurd up against the ropes. In the fourth, Welborn started fast as he did in the previous rounds, once again backing Hurd up against the ropes. Untroubled by Welborn's power, Hurd took the centre of the ring and began to throw heavy punches, ending with an accurate shot to the body that put Welborn down. He managed to get to his feet at the count of ten but referee Lou Moret waved the fight off.
