Ronald "Ron" Welty (born February 1, 1971, in Long Beach, California) is the former drummer for the American punk rock band The Offspring. Of all the band's drummers, Welty's tenure was the longest, as he was in the band from July 1987 to March 2003.
He had replaced their second drummer James Lilja, and was only 16 at the time of his joining. However, he left to form his band Steady Ground, in which he played drums and co-produced. His departure was announced on March 18, 2003 on The Offspring's official website.
He had played on The Offspring's first six studio albums before departing, which were their self-titled album, Ignition, Smash, Ixnay on the Hombre, Americana, and Conspiracy of One. He left the band when they were in the midst of writing and recording Splinter, their seventh studio album released in December 2003.
On February 26, 2006, Steady Ground released three demos on Myspace, entitled "Everyone's Emotional", "I Can't Contain Myself", and "You Better Close Your Eyes." In 2007, the band released the studio album Jettison, and in the same year they broke up.
