Titanium welding wire, as a special welding material, has excellent mechanical properties and corrosion resistance due to its titanium content, which makes it widely used in a variety of industrial fields.
What is titanium welding used for?
Laser filler wire welding: titanium welding wire in laser filler wire welding shows good weld shaping ability and organizational properties, especially in the welding of TC4 titanium alloy plate, you can get a high-quality weld.
Underwater welding: TC4 titanium alloy laser filler wire welding technology has been successfully applied in the underwater field, and high-quality underwater welds can be obtained after optimizing the welding parameters.
Aerospace: Titanium welding wire is used for the filler welding of turbine disks and blades of aviation jet engines, as well as the welding of the magazine.
Chemical industry: due to its corrosion resistance, titanium welding wire is used in the chemical, pharmaceutical, paper, and other industries for the repair of equipment and the manufacture of new equipment.
Medical industry: Titanium alloys have become one of the most successful metallic materials in the field of biomedical engineering, used in the production of orthopedic implants, dental restorations, and cardiovascular devices, among others.
Properties of titanium welding wire
Mechanical properties: By choosing the right titanium welding wire and optimizing the welding process, the overall performance of the welded joint can be effectively enhanced.
Corrosion resistance: Titanium wires contain alloying elements such as Ni, Co, Cr, Pd, Ru, etc. that significantly improve the corrosion resistance of the weld.
Microstructure control: laser wire filling welding technology can effectively control the distribution of needle martensite in the central zone of the weld and the grain size of the heat-affected zone.
Related Processes
Optimization of welding parameters: By adjusting parameters such as welding speed, wire feed speed, and laser power, well-formed, continuous, and stable welds can be obtained.
Pre-treatment methods: These include beveling, cleaning of bevels and wires, preheating before welding, and chemical treatment, which help to improve the quality of the weld.
Welding wire preparation methods: For example, the preparation method of Cu-Ag-Cr wire for titanium-pipeline steel welding can reduce the welding stress in the transition layer and improve the strong toughness of the weld.
Challenges
Water-port incrustation problem: This problem can be effectively solved by analyzing the causes of water-port incrustation of titanium-containing welding wire steels and improvement measures.
Pourability study: By controlling the process parameters, the pourability of the steel can be significantly improved and the quality of the welding wire can be enhanced.
