FIELD: welding, namely, apparatus for welding bodies of self-propelled transport vehicles. SUBSTANCE: apparatus for welding bodies of self-propelled transport vehicles or body parts such as walls had been assembled insufficiently tightly includes two rotary drum 13 for rapid change of frames 12 in order to place members to be welded in operative position for their welding according with type of construction being welded. Different mounting frames rotated by rotors 19 are directed along annular track 23 on each rotary drum 13. Portion 25 of each annular track 23 may be separated and displaced along line of conveyor for constructions being welded in order to locate mounting frame in operative position. EFFECT: enhanced serviceability of apparatus. 5 cl, 6 dwg
