Due to the strong activity of the titanium tube, the welding temperature control, the protective effect of the shielding gas, the welding environment, and other aspects are strictly required in the welding of the Grade 3 Pure Titanium Tube. In severe cases, the product will be scrapped. The practice has proved that: by analyzing the main factors affecting the welding quality, determining the key welding process, and strengthening the control of the environment, personnel, welding parameters, and methods in the welding process, the welding quality of titanium tube materials can be effectively guaranteed to be further improved. Improve, and prevent the appearance of welding scrap.
In recent years, a new Grade 9 Ti3Al2.5V Titanium Tube material has been widely used. Due to the properties and characteristics of lightweight, high strength, and corrosion resistance, titanium alloys are widely used in the fields of aerospace, petrochemical, and machinery manufacturing, and are also used in the construction of surface ships for the first time. However, since titanium alloy is a highly active metal, it has a great affinity for oxygen, hydrogen, nitrogen, and other gases at high temperatures, that is, it has a strong ability to absorb and dissolve gases, especially in welding process. This ability is particularly strong with increasing soldering temperature. The practice has proved that if the absorption and dissolution of titanium alloy and oxygen, hydrogen, nitrogen, and other gases are not controlled during welding, the product will eventually be scrapped. Therefore, in the welding of titanium pipe joints, effective prevention and control must be carried out to meet the quality requirements of welding.
