Description
Technical Field
[0001] The present application relates to the technical field of corrugated pipe production, and in particular to a welding device for producing corrugated pipes. Background Art
[0002] Pipes come in a variety of shapes, each with its own specific operating environments. Bellows are tubular elastic sensitive elements formed by folding corrugated sheets connected along the folding and contracting direction. Bellows are widely used in instrumentation, primarily as measuring elements in pressure gauges, converting pressure into displacement or force. Bellows have thin walls and high sensitivity, with a measurement range from tens of Pa to tens of MPa. The open end is fixed, while the sealed end is free. A supplementary coil spring or reed is used to increase elasticity. During operation, the pipe expands along its length under the influence of internal pressure, causing the movable end to move in a manner proportional to the pressure. This movable end drives a pointer, directly indicating the pressure level. Bellows are often combined with displacement sensors to form pressure sensors with electrical outputs and are sometimes used as isolation elements. Because bellows expansion requires a large volume change, their response speed is slower than that of conventional bellows. Bellows are suitable for measuring low pressures. Bellows are typically welded from 0.5 mm thick spiral stainless steel stampings, requiring laser welding at the joints. Due to the existing welding process, it is difficult to control the stamping accuracy, elastic deformation, welding thermal deformation and tooling positioning during production, resulting in many welding defects. The existing welding equipment has low welding efficiency and a long welding time. Utility Model Content
