Technical Field

[0001] This utility model relates to a metal welding device, specifically an automated welding auxiliary device for metal parts. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technique that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure.

[0003] Chinese patent (CN 109848628 U) discloses a welding auxiliary device for automated processing of precision mechanical parts. This patented technology provides a welding auxiliary device for automated processing of precision mechanical parts.
