Description

Technical Field

[0001] The utility model relates to an air duct welding technology, in particular to a highly sealed air duct automatic welding device. Background Art

[0002] Metal ducts are often used for ventilation and air supply ducts, oil fume and dust removal ducts, and the connection between ducts is usually fixed by welding. Manual welding of ducts is usually done by two people, one person uses a tool to drive the duct to rotate, and the other person operates the welding equipment to weld the two ducts. The work intensity is high, and the close-range operation is more harmful to the human body.

[0003] In the prior art, there are already air duct welding equipment with automatic functions, such as patent CN116117423A, but the air duct welding equipment proposed in the patent has a low degree of automation and is only applicable to thick-walled air ducts that are not easily deformed, and has a small scope of application.
