A kind of welding method of thin plate and thick plate

Abstract

The invention discloses a welding method for a thin plate and a thick plate, and relates to the technical field of welding. By fixing the position of the thin plate to be welded and the position of the thick plate to be welded, the position of the thin plate to be welded is flanged, the flanging distance is 2-4 times that of the thin plate, the flanging angle is 30°-90°, and the The welding equipment is prepared, the flanging position on the thin plate is moved, and the flanging position of the thin plate is fitted with the position to be welded on the thick plate, and the edge position after the flanging is welded by the welding equipment, after welding , cool for a certain period of time, remove the welding slag on the surface, check the integrity of the welding, and the welding is over, which solves the problem that the thermal stress generated by welding will cause a large overall deformation of the product, the accuracy cannot be guaranteed, and the quality of the weld seam is not easy to guarantee. The overall deformation of the bracket affected by the stress is small, which ensures the accuracy, and at the same time, the quality of the weld is easier to guarantee.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding method for a thin plate and a thick plate. Background technique [0002] Welding, also known as welding, is a manufacturing process and technique that uses heat, high temperature, or pressure to join metal or other thermoplastic materials such as plastics. [0003] There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. In addition to its use in factories, welding can also be performed in a variety of environments, such as in the field, underwater and in space. Welding, wherever it occurs, can pose a hazard to the operator, so proper precautions must be taken when welding. Possible injuries caused by welding to the human body include burns, electric shock, visual impairment, inhalation of toxic gases, and excessive ultraviolet radiation. [0004] The traditional welding method of thi...
