Abstract of Disclosure A method for controlling a bead, in one-side automatic welding wherein a backing metal strip is adhered to the back side of a pair of work pieces through an inorganic material and arc welding is applied to the work pieces on the surface side thereof, comprises: detecting an electrical signal between the work pieces and the backing metal strip to control a weld current 80 that the detected electrical signal can be equal to a predetermined reference signal: and detecting the controlled weld electrical current and putting the detected weld electrical current into a formula of V1 = VO?IL/ILO to calculate a welding speed and to control the welding speed, where V1 represents the welding speed, VO an initial value of the welding speed, IL the detected weld electrical current and ILO a predetermined reference weld current. The electrical signal can be an electrical signal or a voltage signal.
