Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a welding transfer mechanism for an automatic welding machine. Background Technology

[0002] Most components today are made of metal, but welding is an indispensable machining process in component manufacturing. Welding, also known as fusion or melting, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding uses a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound.

However, manual handling is time-consuming and labor-intensive, which greatly reduces the machine's working efficiency and limits its practicality. Therefore, we propose an automatic welding transfer mechanism to solve this problem. Utility Model Content
