Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding device for a container tank body. Background Art

[0002] Metal container tanks are often used in today's chemical and other industries. They can withstand high pressures and are often used to store gases, liquids or mixtures. The tank body of a container tank is generally a cylinder, and these tank bodies usually need to be welded. When the tank body is produced, the metal plate is first cut into the required size, and then the metal plate is curled into a suitable arc, and then the two unbent sides of the metal plate are aligned and welded to form the cylindrical body of the tank. When welding the opposite sides of the metal plate, in order to prevent the thermal stress generated during welding from causing the metal plate to shift and affect the neatness of the welding, it is necessary to first perform spot welding and fix it, and then perform overall welding. When welding the tank body, the weld needs to be aligned and then spot welding is performed. However, the tank body will shift during welding, affecting the accuracy of the welding, and the tank body needs to be fixed. Utility Model Content
