Copper, nickel and titanium
Copper, nickel and titanium – interactive engineering module focused on welding copper nickel titanium. Learning format: Decision guide · Active learning. Explains the principle, technical relationships and practical use.
Topic overview
These materials do not form one technology group. Copper removes heat rapidly, nickel demands strict control of cleanliness and solidification, and titanium reacts aggressively with the atmosphere when hot. Their common requirement is exact alloy identification and a qualified process regime.
Is the alloy unambiguously identified, and is the dominant failure mechanism known: inadequate heat, hot cracking, contamination or corrosion incompatibility?
Power and preheat must overcome rapid heat extraction without excessive overheating and distortion.
Trace contamination, unsuitable filler and a large pool promote segregation and hot cracking.
