Description
Technical field
The present invention relates to electrothermal tube manufacture technology field, is the welding procedure of a kind of electrothermal tube semi-finished product and ring flange specifically.
Background technology
Electrothermal tube is applied commonplace in life, in the production and assembly process of half-finished electrothermal tube and ring flange, in order to improve installation quality and the production efficiency of semi-finished product cell heat pipe and ring flange, need technological process and the operating procedure of an optimization, and welded and installed also has other parts on ring flange together with semi-finished product cell heat pipe, in order to improve bonding strength and the installation quality of different parts and ring flange, need different technical parameters to coach.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the welding procedure of a kind of electrothermal tube semi-finished product and ring flange.
Technical problem to be solved by this invention realizes by the following technical solutions:
A welding procedure for electrothermal tube semi-finished product and ring flange, this technique comprises the following steps:
(1) prepare: qualified ring flange, sleeve pipe, Nut column, magnesium rod frame, temperature tube, semi-finished product cell heat pipe are placed in corresponding spare part frame;
(2) print mark: on ring flange, print mark, and one end of temperature tube is flattened, adopt afterwards argon arc welding shutoff;
(3) spot welding is reinforced: by drawing, first sleeve pipe point is welded on two pore positions of flange back side regulation, then by 3 reinforcings of mode spot welding of argon arc welding, afterwards the parts such as Nut column, magnesium rod frame are welded by the mode of argon arc welding respectively with ring flange successively, adopt the mode of argon arc welding or Laser Welding to weld respectively with ring flange successively electrothermal tube semi-finished product, temperature tube again, tighten up sleeve pipe afterbody simultaneously;
(4) soldering: the root of all ring flange back side metal tube fixtures is all stamped to Ni-based soldering paste, then carry out high temperature brazing through furnace for brightness.
The technical parameter difference of taking for the welding of different parts, specific as follows:
(1) mash welder: sleeve pipe and ring flange: 320 ± 20V/0.3 ± 0.1MPa;
(2) argon arc welding machine: argon pressure is: 0.15MPa;
(3) laser welder: electrothermal tube semi-finished product and temperature tube and ring flange: 190 ± 10A/4.2 ± 0.2ms/14Hz;
(4) furnace for brightness welding: electrothermal tube semi-finished product and temperature tube and ring flange: 1065 ± 10 ℃/28 ± 3Hz.
The invention has the beneficial effects as follows: the present invention has improved the welded and installed intensity of semi-finished product cell heat pipe and ring flange, improve the welding efficiency of semi-finished product cell heat pipe and ring flange, different welding assemblies adopts different welding manners and solder technology parameter to improve the bonding strength of all parts and ring flange, has guaranteed welding quality.
