Description

Technical Field

[0001] The utility model relates to an oblique welding head type welding machine tool. Background Art

[0002] There are many different welding machines available on the market, but the most common one is a straight-up, straight-down welder. Because of this straight-up, straight-down structure, this type of welder can only operate on workpieces with flat surfaces and is not suitable for plastic cover plates, which affects the versatility of this type of welder. For example, a wiper motor requires soldering contact plates to the cover plate. This cover plate has a bumpy surface and a structure that is not suitable for straight-up, straight-down welders. With existing technology, employees can only use a soldering iron to solder the contact plates, which can easily cause poor soldering and continuous soldering. Furthermore, soldering is inconvenient with two hands, and the cover plate is difficult to secure, which increases the difficulty of the employee's work and reduces production efficiency.
