Medical grade titanium alloy Marine titanium welding process

In recent years, many new ships began extensive use of titanium alloy . With the increase in the amount of titanium alloy materials , shipyard welding to enhance efficiency , product quality and stability , the need to develop some efficient titanium welding process. TA5 two kinds of titanium Shanghai Jiangnan Shipbuilding in titanium grade 4 thickness of 4mm Ti70 and 16 mm for welding object, plasma arc welding , laser welding and laser - arc hybrid welding seamless titanium tube welding three high energy density of the process carried out explore, get the excellent performance of welded joints
A plasma arc weldingPlasma arc welding is the use of plasma arc welding method as a heat source . Gas heated by the arc generated from the solution , a nozzle at high speed compressed by water , and increasing the energy density of the solution from forming a plasma arc. Its stability , heat and temperature are higher than the arc , and thus has a greater penetration power and welding speed .

Titanium bars Performance and titanium alloys are widely used in industry

titanium grade 2 sheet because of its high strength, heat resistance, corrosion resistance, widely applied in industry . Especially in aviation, aerospace , shipbuilding and other industries , mostly used in the manufacture of titanium alloy key components , its performance is good or bad usually determines the level of the product . Therefore , national research institutions to put a lot of manpower, material and financial resources to carry out its melting alloys and equipment , forming process research and development , writing papers , and many thousands of monographs . However, the study of titanium melting process with little , limited studies have limited studied. Titanium because of its high melting point, titanium grade 4 chemical activity , thermal properties between the elements of the big difference , so the smelting process of melt composition and temperature control is very difficult, and the melt composition and temperature directly determine the quality of titanium . Therefore , to identify qualitative and quantitative variation of melt composition, temperature and process parameters , alloy itself between thermal parameters have important practical significance for guiding titanium melting , smelting practice for other alloys also have important reference value
