| description | The invention relates to a resistance welding process and structure for a barrel and a sealing cover, and the resistance welding process comprises the following steps: S1, preparing the barrel and the sealing cover, and preforming a structure suitable for welding on the barrel and the sealing cover; s3, welding is conducted, an upper electrode descends to press the sealing cover, a nugget area is formed at the contact position between the sealing cover and the barrel, after the pressure reaches a set value, a resistance welding machine discharges, large current passes through the nugget area to enable the nugget area to be heated and liquefied, and after liquefied metal is cooled, the barrel and the sealing cover are fixedly connected into a whole; and S4, material taking. Structures suitable for welding are formed on the barrel and the sealing cover in advance, welding flux and welding flux do not need to be added, shaping treatment does not need to be conducted on the barrel or the sealing cover before weld |
