Description

Technical Field

[0001] The utility model relates to the technical field of kettle production, in particular to an argon arc welder for kettle processing. Background Technique

[0002] Most kettles used in families are made of stainless steel, which are not only durable but also beautiful. However, in the production process of stainless steel kettles, some structures with curved surfaces cannot be directly shaped and need to be integrally spliced by an argon arc welder. For example, the lid of a stainless steel kettle is argon arc welded to the kettle body.

[0003] Argon arc welding technology is based on the principle of ordinary arc welding. By using argon gas to protect the metal welding material, a high current is used to melt the welding material into a liquid state on the base material to be welded to form a molten pool, enabling the base metal and the welding material to achieve metallurgical bonding. Since argon gas is continuously supplied during high-temperature melting welding, the welding material cannot come into contact with oxygen in the air, thus preventing the oxidation of the welding material. Therefore, it can weld stainless steel, iron and other metal hardware.

[0004] For the welding of the kettle lid and the kettle body, the kettle lid needs to be pressed tightly on the kettle body through a pressing device, and then the contact position between the kettle lid and the kettle body is welded by an argon arc welding gun. During the welding process, the kettle lid and the kettle body need to be closely connected at the weld position. However, for thin-walled kettle bodies and kettle lids, due to their thin wall thickness, it is not easy to accurately align the kettle body and the kettle lid during pressing and welding, and the relative position of the contact between the kettle body and the kettle lid is likely to change during the welding process, resulting in unsatisfactory welding effects and a high defective rate. To facilitate the accurate butt welding of the kettle body and the kettle lid, we propose an argon arc welder for kettle processing. Content of the Utility Model
