[0002] Since the sheet metal material factory produces materials with certain specifications, most of the material width specifications are between 1000 mm and 2000 mm. When large sheet metal materials with a width of more than 2000 mm are used in the production process, riveting, Bite, manual welding and other methods not only have high work intensity, but also have certain restrictions on appearance

Embodiment Construction
[0030] The present invention will be further described below in conjunction with embodiment (accompanying drawing):
[0031] In the welding method of large metal sheets of the present invention, the metal sheets include metal sheets or rolls, and the method includes the following steps:
[0032] a. For the coiled sheet, firstly, the coiled sheet metal material is uncoiled and unrolled by the uncoiling device;
[0033] b. Guide the unfolded sheet metal material or sheet metal to the crimping device;
[0034] c. The two sides of the sheet metal material are curled up symmetrically through the curling forming device, and the curling height is 2mm-8mm;
[0035] d. Lay at least two sheet metal materials of the curling side by side, and align the adjacent curling edges of every two adjacent sheet metal materials, and weld the adjacent curling edges of the two sheet metal materials It is melted and welded into a whole, and finally the materials of the required specifications are ta...

Abstract
The invention discloses a welding method and a device for large-sized metal sheets. The sheet metal materials are weldable metal materials such as stainless steel, titanium alloy, aluminum alloy, copper plates, galvanized plates or carbon steel plates being 0.20 to 4.5 millimeters in thickness. The implementation process flow of the welding method and device consists of an uncoiling device A, a transition platform B, a crimping molding device C and an automatic welding device D. The method comprises the following specific steps: (1) symmetrically crimping both sides of a sheet metal coil stock (or plate) upwards, wherein the crimping height is 2 to 8 millimeters; (2) crimping and aligning two pieces of crimped materials on a flat plane, and melting and welding the two pieces of crimped materials into a whole with a welding gun; (3) continuously performing aligning, melting and welding in order to produce large-sized metal sheet materials which meet demands. By adopting the welding method and device, the problem of specification limitations on the metal sheet materials is effectively solved, and meanwhile the appearance quality of automatic welding is superior to the appearance quality of the conventional method.
Description
technical field [0001] The invention relates to an urban domestic sewage treatment project, a transfer storage of urban domestic drinking water, and a large-scale environmental protection project; a large-scale liquid (pure water, beer, beverage, liquor, etc.) storage tank; ; and the processing method and device of large metal sheet that can be used in fields such as aircraft, trains, and large passenger car shells——the welding method and device of large metal sheet. Background technique [0002] Since the sheet metal material factory produces materials with certain specifications, most of the material width specifications are between 1000 mm and 2000 mm. When large sheet metal materials with a width of more than 2000 mm are used in the production process, riveting, Bite, manual welding and other methods not only have high work intensity, but also have certain restrictions on appearance. Contents of the invention [0003] The purpose of the invention of this patent is to ...
