How To Improve The Quality Of Titanium Tube Welding?

Due to the strong activity of titanium tubes, there are strict requirements for temperature control, gas protection, and welding environment in the implementation of titanium tube welding. A slight mistake can have a significant impact on welding quality, and in severe cases, it can lead to product scrapping. Practice has proven that by analyzing the main factors affecting welding quality, determining the key welding processes, and strengthening the control of the environment, personnel, welding parameters, and methods during the welding process, the welding quality of titanium pipe materials can be further improved, and the occurrence of welding waste can be prevented.
In recent years, a new type of titanium tube has been widely used. Titanium alloy, due to its light weight, high strength, and corrosion resistance, is widely used not only in aerospace, petrochemical, mechanical manufacturing and other fields, but also in the construction of pipeline systems for surface ships. However, due to titanium alloy being an active metal, it has a strong affinity for gases such as oxygen, hydrogen, and nitrogen at high temperatures, which means it has a strong ability to absorb and dissolve gases. Especially during welding, this ability is particularly strong as the welding temperature increases. Practice has shown that if the absorption and dissolution of titanium alloys and gases such as oxygen, hydrogen, and nitrogen during the welding process are not controlled, the product will be scrapped. Therefore, the welding of titanium pipe joints must be effectively prevented and controlled to meet the quality requirements of welding.
Welding requirements for titanium pipe joints:
Welding personnel should wear clean work clothes and there should be no oil stains present. Welding gloves should be made of white gauze, and wearing gloves made of cotton thread or other fabrics is strictly prohibited.
The layout of the welding platform and the wire brushes in the welding area of the welding joints should be made of stainless steel materials, and the use of other polluting materials such as carbon steel is strictly prohibited.
Welding sites should be set up indoors or in dedicated welding studios as much as possible. Smoking is strictly prohibited indoors. The environment should be kept clean and dry. The room temperature should not be lower than 5 ℃, and air convection should be strictly controlled.
In order to achieve good welding quality, the end of the docking pipe should be processed into a V-shaped groove as much as possible, and the welding area and welding wire surface should be degreased with acetone.
