Problems solved by technology
The parallel tube bundle is composed of multiple capillaries. During the processing, the capillaries need to be welded to the end cover plates on both sides, but the traditional welding device cannot accurately position the capillaries, and they need to be welded one by one during the welding process. Welding, its welding efficiency is very low
On the other hand, due to the surface tension of the welding liquid, the traditional welding device is not easy to fill the gap between the end cover plate and the capillary, and it is also difficult to weld the inner hole of the capillary. This problem leads to the welding of the capillary. It is easy to desolder
The traditional welding device cannot adjust the wire output speed according to the diameter of the welding wire, which may easily cause insufficient or excessive welding fluid

The invention discloses a capillary anti-dissoldering welding device for a tubular heat exchanger, which relates to the technical field of capillary welding and includes a fixed component, a moving component, a welding component, an end cover positioning component, a bottom plate, a moving component, an end cover positioning component and a bottom plate The upper surface is fastened and connected, and there are four groups of fixed components and moving components. The four groups of fixed components are respectively installed on different moving components, and the welding components are installed on the fixed components. The present invention can keep the welding wire output per unit time in a relatively stable state through the timely correction of the welding wire output speed, and the stable welding wire output provides the basis for the welding to reach the standard. The invention completely fills the welding gap by means of negative pressure diversion, and also welds the end cover plate and the inner hole of the capillary tube, which greatly improves the welding strength and prevents the occurrence of desoldering.
Description
technical field [0001] The invention relates to the technical field of capillary welding, in particular to a capillary desoldering prevention welding device for a tubular heat exchanger. Background technique [0002] The tube heat exchanger is a typical partitioned wall heat exchanger, which has a very long history in industrial application, and still occupies a dominant position in all heat exchangers. The tubular heat exchanger is mainly composed of a shell, a tube bundle, a tube sheet and a head. fixed on the tube sheet. The parallel tube bundle is composed of multiple capillaries. During the processing, the capillaries need to be welded to the end cover plates on both sides, but the traditional welding device cannot accurately position the capillaries, and they need to be welded one by one during the welding process. Welding, its welding efficiency is very low. On the other hand, due to the surface tension of the welding liquid, the traditional welding device is not e...
