When the diameter of the titanium screw is less than 30mm and the center line is offset within 30mm, you can first bake the bolt red with oxyacetylene, then use a sledgehammer to bend the bolt (or use a jack to bend it). After correction, use a steel plate to weld it firmly and reinforce it. Prevent recovery when tightening bolts.
If the spacing of the titanium bolts is wrong, you can use an oxyacetylene flame to bake them red and then use a sledgehammer to bend them, weld a steel plate in the middle for reinforcement, and fill them in during subsequent grouting.
For large bolts (diameter above 30mm) when there is a large deviation, the bolt should be cut off first and a steel plate should be welded in the middle of the bolt. If the bolt is not strong enough, two reinforcing steel plates can be welded on both sides of the bolt. Their length must not be 3 to 4 times smaller than the bolt diameter.
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 its strength is low and its plasticity is high. The properties of 99.5% industrial pure titanium are: density ρ=4.5g/cm3, melting point 1725℃, thermal conductivity λ=15.24W/(m.K), tensile strength σb=539MPa, elongation δ=25%, and cross-sectional shrinkage Rate ψ = 25%, elastic modulus E = 1.078×105MPa, hardness HB195.
