Welling was born in Putnam Valley, New York. His father is a retired General Motors executive and his mother a home engineer. He has two older sisters, Rebecca and Jamie, and a younger brother, Mark, who is also an actor. His father's job often required relocation, first moving from Putnam Valley, New York (his birthplace) to Hockessin, Delaware, then settling in Okemos, Michigan at the beginning of Tom's sophomore year in high school.
Welling was active in many team sports including baseball, basketball, and excelling in soccer, playing the position of goalkeeper. He graduated from Okemos High School in 1995. After graduation he worked as a construction worker and continued to live with his parents.
In 1998, Welling was discovered by a catalog shoot scout who suggested he try modeling. In 2000, Welling relocated to Los Angeles where he modeled for Tommy Hilfiger and others, while simultaneously pursuing an acting career. Welling's first major role was six episodes on Judging Amy in 2001, playing opposite Amy Brenneman, and as a love interest and karate teacher. He later appeared in Special Unit 2 and Undeclared. He was chosen as Clark Kent in Smallville after a nationwide search.
In December 2003, Welling played the oldest son of Steve Martin in the big screen adaptation of Cheaper by the Dozen. He has now since appeared in the sequel Cheaper by the Dozen 2, and the horror remake of The Fog. Despite rumors that have swept the internet, Welling was not considered for the part of Superman in the movie Superman Returns. Director Bryan Singer was searching for a fresh new face to play the role and had specifically stated in an interview on the movie's website that Welling had not been considered.

Aquaman and his new wife Mera team up with Clark to free Oliver. Lois is frustrated when Clark continues to push aside her offers to help the team and sets out to prove she can play with the big boys.
- Booster (written by Geoff Johns) - After everything that happened with the VRA, Lois tells Clark it's best to make "Clark Kent" forgettable and awkward so people don’t suspect he’s The Blur. However, the two are stunned when a fame-hungry superhero from the future, Booster Gold, sweeps into town and begins making saves and posing for press ops, completely winning over the city of Metropolis. Booster begins his campaign to take The Blur’s place as the "World’s Greatest Superhero" and tries to charm Lois into writing a story about him, but she’s not having his antics and begins her own campaign for The Blur. During one of Booster’s saves, an alien weapon in the form of a scarab falls from a truck and fuses itself to a boy named Jaime Reyes, turning him into the Blue Beetle. Unfortunately, Jaime is unable to control the suit and Blue Beetle starts attacking Metropolis.
