Welding of titanium and titanium plate


Material characteristics and welding of Xinnuo medical titanium alloy and titanium alloys , and titanium and titanium alloy for welding prone to oxidation, cracking , porosity chip welding defects,
welding tests carried out . Can live for titanium and titanium alloy welding procedure specification of trial and error, and a reasonable analysis of the testing process
problems , summed up the characteristics of titanium and titanium alloy welding process and operating essentials . Weldability of nickel rod and titanium alloys , with many
notable features , these features are due to the welding of titanium and titanium alloy physical and chemical properties of the decision. At room temperature , titanium and
titanium alloys are relatively stable. However, the test table , in the welding process , the droplet and the pool of liquid metal having a strong absorption of hydrogen,
oxygen, nitrogen, role, and in the solid state , with these gases have a role. With increasing temperature , thin titanium sheet and titanium alloys absorb hydrogen , oxygen, nitrogen
capacity also will rise significantly , about 250 ℃ began to absorb hydrogen , began to absorb oxygen from 400 ℃ , 600 ℃ began to absorb nitrogen from these gases after being
absorbed, will directly cause embrittlement of welded joint is extremely important factor affecting the quality of welding .
