Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a multi-point welding workbench. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Welding achieves the purpose of joining through the following three methods: Fusion welding, which heats the workpieces to be joined to partially melt them to form a molten pool, and the molten pool cools and solidifies to form a joint. Filler material can be added if necessary. It is suitable for welding various metals and alloys and does not require pressure. Pressure welding, which requires pressure to be applied to the workpieces during the welding process, is suitable for the processing of various metal materials and some metal materials. Brazing, which uses a metal material with a lower melting point than the base metal as a filler metal, uses liquid filler metal to wet the base metal, fill the joint gap, and diffuse with the base metal to achieve the connection of the workpieces. It is suitable for welding various materials, as well as different metals or dissimilar materials. During the welding process, the workpiece and the filler metal melt to form a molten area, and the molten pool cools and solidifies to form a connection between the materials. Pressure is usually required during this process. There are many energy sources for welding, including gas flame, electric arc, laser, electron beam, friction, and ultrasound.

[0003] Currently, existing product parts require multi-point welding. The original process involves fixing the parts on a welding fixture and then using a suspended spot welding machine to weld multiple points. However, the suspended spot welding machine is cumbersome to operate and requires two people to operate, resulting in low welding efficiency and wasted manpower. Especially in the welding of rings, welding needs to be done around the outer circumference of the ring, which involves a large amount of welding and high labor intensity. In response, this utility model provides a multi-point welding workbench. Utility Model Content
