摘要： A clamping device includes a backing member (4) having an upper face (44) pressing against two work pieces (1) having a welding gap (11) therebetween. A rod (3) extends through the backing member (4) and has an exposed upper portion (3A) extending through a narrower portion (13) of the welding gap (11) into a wider portion (14) of the welding gap (1). An elastic element (34) is mounted between a bottom face (46) of the backing member (4) and an abutting portion (32; 32A) on a lower portion (3B) of the rod (3) to bias the backing member (4) to press against the work pieces (1). The upper portion includes a hooked section (31; 31A) having a first width (W1) smaller than a width of the narrower portion (13) and a second width (W2) perpendicular to and larger than the width of the narrower portion (13). The rod (3) is turnable to a position in which the second width (W2) of the hooked section (31; 31A) presses against the work pieces (1) under the action of the elastic element (34).
