Problems solved by technology

[0002] At present, for many heat pipes, such as various types of water-immersed heat pipes, when the temperature control and heat conduction part of the flange is connected to the heat pipe, the ordinary heat pipe flange is only connected to the temperature control part with a hole, without any additional Parts with good heat transfer performance need to be electroplated or sandblasted after welding, so the production efficiency is not high and the cost will increase accordingly

Embodiment Construction

[0030] The specific implementation of the present invention is as follows: stainless steel heating tube, including stainless steel electric heating tube 5, flange piece 8, screw column 12, heat conduction copper sheet 11, the whole welding process comprises the following steps:

[0031] (1) Connect the screw post 12 to the flange piece 8 by butt welding;

[0032] (2) Butt weld the heat-conducting copper sheet 11 on the groove position 9 of the flange sheet 8;

[0033] (3) Connect the pit temperature control position heat conduction part 4 on the flange sheet 8 with the stainless steel electric heating tube 5 by butt welding;

[0034] (4) The nozzle 1 of the stainless steel electric heating tube 5 and the hole 3 of the flange 8 are welded by laser.

[0035] Wherein, steps (1) and (2) can also be moved to steps (3) and (4).

[0036] First of all, the three screw columns 12 are connected with the flange piece 8 in a triangular form by the method of butt welding, and the welding...

Abstract

The present invention discloses touch welding process between the flange for stainless steel pipe and the electrically heated stainless steel pipe. The flange has at least one raised spot in the notched part to raise the touch welding efficiency and reduce the influence on the surface color of welded stainless steel pipe. Compared with common welding process, the touch welding process is firm, high in welding quality, fast, saving in material. Laser welding may be further used after touch welding. One kind of heating stainless steel pipe for the said technological process is also disclosed.

Description

technical field [0001] The invention relates to a production and processing process of a heating tube, in particular to a welding process of a stainless steel heating tube. The present invention also relates to a stainless steel heating tube using the above process. Background technique [0002] At present, for many heat pipes, such as various types of water-immersed heat pipes, when the temperature control heat conduction part of the flange is connected to the heat pipe, the ordinary heat pipe flange is only connected to the temperature control point with a hole, without any additional Components with good heat transfer performance need to be electroplated or sandblasted after welding, so that the production efficiency is not high and the cost is correspondingly increased. At the same time, the welding process of the two nozzles of the heating tube and the flange piece of the submerged heating tube is traditional welding torch, furnace welding or argon arc welding. Burning...
