The production of titanium and titanium alloy welding wires in China mainly adopts Chinese national standards, American national standards, and Russian standards.
The establishment of titanium and titanium alloy systems in the United States is mainly for the aviation and aerospace industries. The US AWS welding wire material standard has established corresponding grades of welding wire for the titanium and titanium alloy grades involved in the United States, and the update speed of the standard is relatively fast. In the current version, the code regulations for welding wire are unified with ISO, which is convenient for promotion and use.
Russia has inherited the titanium and titanium alloy system established by the former Soviet Union, which is mainly used to serve the aviation, aerospace, ship, and nuclear industries. The established welding wire standards are different from the United States and ISO titanium welding wire standard systems due to differences in design concepts. , mainly used in the former Soviet Union and countries that introduced Russian titanium and titanium alloy systems.
The Japanese titanium and titanium alloy system mainly serve the civilian market, such as the chemical industry, building materials, and other fields. The established titanium welding wire standard system is matched with the titanium and titanium alloy processing system, and the welding wire grade and coding system are consistent with ISO.
my country's titanium industry started relatively late, but a complete system of titanium and titanium alloys has been established through the imitation of foreign materials and independent research and development. At present, there are more than 100 titanium and titanium alloy grades. The titanium welding wire standard mainly adopts the American AWS, Russia OCT190015, and other standards, and at the same time adds the welding wire requirements that are compatible with the independently developed titanium alloy grades; although the performance indicators of the international general grade titanium welding wire produced in my country have no gap with foreign advanced standards, they lack Perfect quality assurance system and supporting welding process.
