titanium wires surface reasonable, mainly referring to the titanium wire surface degreasing and paint,surgical implant titanium remove dirt and other foreign residues. Provide surface clean wool. To avoid contamination and scratches in the thermoforming process. Avoid contamination of fine parts in the heat treatment, welding and other thermal processing step, and to ensure a good surface coating and plating. Available gasoline, acetone,medical grade titanium alcohol and other solvents to clean the surface of titanium wire, but this method is not ideal. Using three ethylene steam degreasing atmosphere, plus inhibitor during degreasing, very good. Sodium hydroxide solution and the like is also useful as a cleaning agent, an alkaline degreasing method.
Chen oil or cleaning,titanium plates for sale parts or wool available water film surface quality inspection method test. The part is immersed in cold water, then put the parts from the water one, if the parts clean surface water film will connect into pieces; if the surface of the oil at the end of divisible, then the water film is not continuous.
titanium wires is a silvery white metal that has many excellent properties. The density of titanium is 4.54g/cm3, 43 percent lighter than steel, lighter than the prestigious magnesium slightly heavier.

Note the use of titanium welding wire
1, construction workers and welders should wear clean white fine gauze gloves (non-wearing cotton gloves).
2, the weld area treated and non-contact touch iron items.
3, welding work as much as possible in titanium bar supplier the room, the ambient wind speed should ≤0.5m / s, avoid the drafts affected.
4, welding wire when titanium welding with short arc welding, the use of small heat input welding, the welding nozzle and the holding angle of 70 to 80 degrees.
5, taking over the position welding,grade 3 titanium butt gap is generally about 0.5mm.
6, each weld should be possible once finished welding, seam welding must be connected before the weld interface should be clean, weld meat lap length is 10 ~ 15mm.
7, when the welding torch should not swing around, wire melting end not out of gas reserves.
8, ahead of the welding arc when aspirated, not lifted immediately when the torch extinction, should be delayed gas, until the temperature drops below 250 ℃.
9, a gas mask and protective distance drag the torch should be the shortest better,Titanium tube supplier seek contact with the wall of the smallest gap. When the tube butt welding, forming side welding in order to achieve the requirements of the welding carried out twice: once for the back cover welding (welding when you can not back fill material), and another for forming welding. When the multi-layer welding, must wait before a weld completely cooled, then the next weld bead.

titanium welding wire operation essentials
1, manual welding, weldment between the wire and should be kept to a minimum angle (10 ~ 15 °).medical titanium alloy Wire along the pool front smooth, uniform into the pool, not the end of the wire out of the argon gas reserves.
2, titanium welding wire welding torch without substantially horizontal swing, the swing when required, the frequency is lower,Medical titanium bar the swing amplitude is not too large, in order to prevent the effects of the protection of argon.
3, when the arc and weld finishing off, to continue through argon, until the weld metal and heat affected zone is cooled to remove the gun before the time below 350 ℃.
