PURPOSE: A welding supporter having bead grooves formed on the upper and lower faces in the different shape and size is provided to apply bead grooves on the upper and lower faces to two types of gap between two welding workpieces and to conveniently attach a release paper on the upper and lower faces. CONSTITUTION: Bead grooves(11a,11b) are formed on the upper face and the lower face of a welding supporter(10) in the different shape and size. An aluminum tape(20) attached with a protection release paper is attached to both faces(12) of the welding supporter. The aluminum tape is divided into upper and lower protection release papers(22a,22b). A middle adhesive face(21) of the aluminum tape is attached to the welding supporter. The bead grooves are selected depending on the gap between two welding workpieces.
