Description

Technical Field

[0001] This utility model relates to the field of hose joint welding technology, specifically a semi-automatic hose joint welding device. Background Technology

[0002] Hose connectors are widely used in the shotcrete industry and are essential components for connecting multiple shotcrete hoses. There is a large market demand for them. They are produced by two processes: welding and casting. Due to the thin wall thickness of the workpiece, the casting process is prone to casting defects, low yield, and high overall cost. Therefore, the welding process is now generally used for mass production. In the welding process, a pipe body of standard thickness and length is welded together with a machined disc body.

[0003] However, welding is generally done by hand-held positioning and manual welding, which results in low production efficiency. Manual positioning and manual welding can easily cause injury to the human body, and the welding quality is unstable, with a high scrap rate, uneven weld seams, and an unsightly appearance.
