Description

technical field [0001] The invention relates to the technical field of spiral finned tube production, in particular to a numerically controlled spiral finned tube laser welding forming device and a welding forming method thereof. Background technique [0002] Spiral finned tubes are used as heat exchanging elements, and they work under high temperature flue gas conditions for a long time. Performance. Such as anti-corrosion performance, wear resistance, low contact thermal resistance, high stability and anti-dusting ability, etc. [0003] There are several traditional production methods for spiral finned tubes. [0004] 1. Set of fins: The process of set fins is to pre-process a batch of individual fins, and then use manual or mechanical methods to set the fins on the outer surface of the tube by interference fit according to a certain fin distance. The coordination effect is poor, and the heat conversion efficiency is low. [0005] 2. Inlaid spiral fin: The inlaid spira...
