Description

Technical Field

[0001] This application relates to the technical field of welding tooling, and specifically relates to a tooling and a welding device for welding and fixing. Background Art

[0002] The temperature control equipment in the semiconductor industry has high requirements for airtightness and zero tolerance for the phenomenon of missed welding during welding. Therefore, high requirements are placed on the parallelism and perpendicularity of the end faces of the welded parts during welding, and the welded products do not deform. This poses a great challenge for manual welding, and there are certain unstable factors in manual work.

[0003] Currently, welding such products with a robotic device is a better choice. Replacing manual labor with a robotic device can reduce the hidden danger of leakage caused by welding, thereby improving product quality.

[0004] However, the inventors of this application found that the welding and fixing tooling during the welding of the current robotic device is usually manually fixed. Using a manual welding and fixing tooling for fixing parts may result in certain errors in the parallelism and perpendicularity of the end faces of the welded parts, thereby causing a hidden danger of missed welding during the welding of the robotic device and reducing the welding quality.
