When the diameter of the titanium metric screw is less than 30mm and the center line is offset within 30mm, you can first use oxyacetylene to bake the bolt red, and then use a sledgehammer to bend the bolt (or bend it with a jack). Prevents recovery when the bolt is tightened.
If the spacing of the titanium bolts is not correct, you can use a sledgehammer to bend them after being baked with an oxyacetylene flame and weld a steel plate in the middle to reinforce it, and then fill it to death in the subsequent grouting.
For large displacement of large bolts (diameter above 30mm), the bolts should be cut off first, and a steel plate should be welded in the middle of the bolts. If the bolt strength is not enough, two reinforcing steel plates can be welded on both sides of the bolt. 3 to 4 times smaller than the diameter of the bolt.
Titanium is a new type of metal. The properties of titanium are related to the content of impurities such as carbon, nitrogen, hydrogen, and oxygen. The purest titanium iodide has an impurity content of no more than 0.1%, but it has low strength and high plasticity. The properties of 99.5% industrial pure titanium are: density ρ=4.5g/cm3, melting point 1725℃, thermal conductivity λ=15.24W/(mK), tensile strength σb=539MPa, elongation δ=25%, section shrinkage Rate ψ=25%, elastic modulus E=1.078×105MPa, hardness HB195.
