Abstract
The invention provides a welding technology for an ultra-thin wall inner-threaded TA2 titanium heat dissipating pipe, belongs to the technical field of titanium inner-threaded pipe manufacturing and particularly relates to the cold extrusion, cold rolling forming and high-frequency welding technologies. The production technology comprises the following steps of (1) unrolling; (2) shearing butt welding; (3) first speed matching; (4) turning of a material storage loop; (5) secondary speed matching; (6) first embossing; (7) third speed matching; (8) second embossing; (9) fourth speed matching; (10) hole type planning; (11) V-shaped angle forming; (12) high-frequency induction welding; (13) cooling scar scraping; (14) pipe shape finishing; (15) welding line correcting; (16) eddy flaw detection; (17) shearing blanking; (18) waste material removing; and (19) finished product conveying and rolling. By means of the technological method, the ultra-thin wall inner-threaded TA2 titanium heat dissipating pipe can be efficiently produced, the surface of a part to be welded does not need to be cleaned before welding, and good welding line texture and performance can be obtained.
Description
Technical field [0001] The invention relates to a welding process of an ultra-thin-walled internally threaded TA2 titanium radiating tube, belonging to the technical field of titanium internally threaded tube manufacturing, in particular to the technical fields of cold extrusion, cold rolling and high-frequency induction welding. Background technique [0002] my country is very rich in titanium resources and is a big country in titanium resources. However, for a long time, due to the complex extraction process and difficulty in extraction, the development speed of the titanium industry has been lagging behind that of iron, aluminum, magnesium and other metal industries. At present, my country's titanium and titanium alloy pipe fittings are mainly used in industrial corrosion resistance and shipbuilding fields, such as nuclear power, seawater installations, ships, and salt-alkali industries. [0003] At present, the main manufacturing methods of titanium and titanium alloy seamless...
