Titanium alloy wire mesh according to the use: pure titanium wire can be divided into titanium welding wire, industrial pure titanium wire, hanging with pure titanium wire, medical pure titanium wire. (1) Titanium welding wire is a special welding wire used in welding reactor titanium, storage of acidic or alkaline materials titanium tank, titanium equipment. 1. Construction personnel and welders shall wear clean white gauze gloves (cotton thread gloves are strictly prohibited). 2. It is strictly prohibited to touch iron articles by hand in the treated welding area. 3. Titanium alloy wire mesh welding should be carried out indoors as far as possible, and the ambient wind speed should be ≤0.5m/s to avoid being affected by draught. 4. Short arc welding should be adopted as far as possible, small welding heat input should be adopted, and the Angle between nozzle and welding parts should be maintained at 70 ~ 80 degrees. 5, titanium alloy wire mesh on the joint positioning welding, the butt clearance is generally about 0.5mm. 6. Each weld shall be welded as once as possible. The weld that must be welded shall be cleaned before welding. 7. During welding, the welding torch shall not swing from side to side, and the melting end of the welding wire shall not move out of the gas protection zone. 8. When applying arc welding, air should be supplied in advance; when arc extinguishing, the torch should not be lifted immediately; air supply should be delayed until the temperature drops below 250℃. 9. The distance between gas shield and welding torch should be very short, and the clearance between gas shield and pipe wall should be very small. In pipe butt welding, in order to meet the requirements of single-side welding and double-side forming, the welding is divided into two parts: one is the backside welding (the backside welding can be done without filling material), and the other is the forming welding. For multilayer welding, wait until the previous pass is completely cooled before welding the next pass.
Pure titanium wire in titanium alloy wire mesh is a general term of pure titanium wire. Generally, titanium ingots are produced by sponge titanium smelting, and large diameter titanium rods are produced by spinning titanium ingots. It is a kind of filamentous titanium material produced by drawing multiple molds. In the industry, the base material with a diameter larger than 5.5mm is called titanium rod; the base material with a diameter less than 5.5mm is called titanium wire; the base material with a diameter less than 1.0mm is called micro titanium wire; and the cost ultra-fine titanium wire with a diameter less than 0.1mm.
Titanium alloy screen to achieve high precision, high efficiency filtering speed. When the moisture in the filtration environment is greater than 5, if the material is unconditionally dried, the screen surface and screen hole of the stainless steel screen should be selected for drying. When the moisture content is greater than 8, wet screening should be used. For the material with more flake particles, it is necessary to change the crushing method of the material and the particle size allocation of different crushing method.
