What Are The Main Properties Of Cutting Gr5 Titanium Plate For Welding?

(1) High-temperature cracks: the high-temperature cracks mentioned here refer to the cracks related to welding. High-temperature cracks can be broadly categorized into condensation cracks, microcracks, cracks in the HAZ (heat-affected zone) and reheating cracks.
(2) low-temperature cracks: low-temperature cracks sometimes occur in martensitic cut titanium plates and some ferritic cut titanium plates with martensitic arrangements. Because the primary cause of its onset is hydrogen dispersion, the degree of bonding of welded joints and the hardening arrangement, so the solution is to reduce the dispersion of hydrogen in the welding process, suitable for preheating and post-weld heat treatment and reduce the degree of bonding.
(3) resistance of welded joints: in austenitic cutting titanium plate in order to reduce the sensitivity to high temperature cracking, in the composition depicted on the usual residual ferrite 5% -10%. But the presence of these ferrites leads to a reduction in low temperature resistance. In the duplex cut titanium plate for welding, welded joints in the area of the austenite amount of reduction and the impact on the resistance. In addition, with the addition of ferrite, the resistance value has a tendency to decrease significantly.
