Early life 
Welker was born in Denver, Colorado, but attended college in California. He performed in numerous college plays and formed his own stand-up comedy act which led to him touring in concerts with performers such as The Righteous Brothers and Sergio Mendes. He later performed in areas such as Los Vegas and Lake Tahoe as the opening act for such headliners as Sonny and Cher, Diana Ross and Loretta Lynn.

Voice acting career 
Welker has done over 1,200 voices since the late 1960s, earning him the title of "voice acting god" from some of his fellow voice-over artists. One of Welker's earliest voice-over roles was the Pushmi-pullyu in the film Doctor Dolittle, which starred  guest actress Samantha Eggar. One of Welker's most famous voice roles is that of Fred Jones in the various Scooby-Doo cartoons. He first played "Freddie" in the 1969-1972 series Scooby-Doo, Where Are You!, and has continued voicing the character ever since. Since 2002 (starting with the series What's New, Scooby-Doo?), Welker has been the voice of both Freddie and Scooby-Doo (co-starring with Grey Griffin). 

Welker is also strongly affiliated with The Transformers. He provided the voice for ten of the Decepticons on the 1980s series: Megatron (the Decepticon leader), Soundwave, Skywarp, Mixmaster, Laserbeak, Buzzsaw, Rumble, Frenzy, Ravage, and Ratbat. He also voiced a few Autobots: Mirage, Trailbreaker, Blades, Chromedome, Groove, and Sludge.
