Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of metal guardrail welding, and particularly relates to a metal guardrail welding device. Background Art
[0002] During the welding process of metal guardrails, traditional welding methods often require manual centering of various components. For example, when welding an empty tube to a column, due to the size difference between the empty tube and the column and the lack of an effective positioning device, it is difficult to ensure that the empty tube is accurately located in the center of the column. This can easily lead to an unstable metal guardrail structure after welding, affecting its overall strength and aesthetics. A large amount of smoke and dust is generated during the welding process, which not only harms the health of the operator, but also affects the working environment and reduces work efficiency. At the same time, the temperature of the welding gun is too high during welding, and long-term continuous work may damage the welding gun, affecting its service life. Traditional welding devices lack effective dust reduction and cooling measures. Most welding devices currently on the market can only perform a single welding function, and there is no device that integrates functions such as centering, fixing, dust reduction and cooling. This results in the need to use multiple devices or tools to complete the entire welding process when welding metal guardrails, increasing the complexity and cost of the operation.
