This invention discloses a welding device and process for producing corrosion-resistant stainless steel flexible metal hoses, specifically relating to the field of flexible metal hose welding technology. Before the mesh sleeve and corrugated pipe are pressed together with the clamping ring, they are coaxially positioned and assembled. During the first descent, the stop block within the clamping fixture in the group feeding unit pulls the edge of the mesh sleeve inward, concentrating it away from the subsequent welding area. This prevents the mesh sleeve edge from becoming loose and outward, thus avoiding obstruction of the welding between the joint and the corrugated pipe end. Simultaneously, the unit moves, further limiting the already pulled-together mesh sleeve edge to maintain it in a pulled-together state. The clamping ring, far from the welding area, is then pressed together, providing ample welding space and reducing welding interference. The arc-shaped support drives the flexible metal hose to rotate around its own axis, allowing the welding position to pass sequentially through the welding torch, facilitating the formation of a uniform and continuous annular weld, and improving the stability and consistency of the welding.
