Cutting - like a punch in the desired shape punched out the hair department. Concentric shape of titanium, the maximum titanium grade 2 sheet cutting thickness of 3.2 mm, the maximum thickness of the irregular shape of the wool is 1.3 mm. 1.3 mm thick titanium plate below, filling the mold with the soil to create a tolerance of 0.1 mm; But for titanium wins 3.2 meters below, shall tolerances down to ± 0.025 mm. Warming will reduce the thickness of titanium cutting edge cracks. Die should titanium plate having rigidity, the upper and lower guide post to maintain the exact relative positions of the mold. When the material thickness increase, such a requirement is more urgent. Less rigid medical titanium process equipment will cause mold damage and cattle production sheet metal edge
1 . Full titanium : Frame in addition to the screws and plastic gloves for outside , all metal parts made of titanium material .2 . Nickel titanium package : Borders titanium material, grade 2 titanium wire the surface material using a nickel package , and now this frame no longer exists.
3 . Assembled Titanium: Due to the high cost of production of nickel and titanium package to update the device , it is not updated before , assembled titanium frames as the situation , but this product is dangerous because each metal has a different melting point, literally Putting it together will be very fragile. Early nickel- titanium frame thin titanium sheet package passes flattened angle , it 's not like a factory original border distribution of production so mean , so after use , nickel, and titanium -coated layer that will break out and no way to weld repair , titanium also includes assembling such a situation .
4 . Nickel-plated titanium : In order to reduce costs, make it easier on the production, but also come up with a factory nickel plated titanium . So then processed using conventional welding techniques .
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 .
