Production Methods and Characteristics of Titanium Welded Tubes - Knowledge

Products Description

Currently, the production methods for titanium welded tubes mainly include high-frequency welding and argon arc welding.

In high-frequency welding, based on the different methods of current introduction, it can be further categorized into high-frequency contact welding and high-frequency induction welding. High-frequency contact welding is highly favored for its high production efficiency and capability for continuous production. Additionally, it features a narrow welding zone and a small heat-affected zone, which helps ensure welding quality. However, this welding method also has some drawbacks, such as high investment costs, complex equipment, and relatively poor weld formation. Therefore, an additional step to remove weld burrs is required during the production process. Moreover, if contact is poor, arcing can easily occur, potentially damaging the tube. In comparison, high-frequency induction welding also offers high production efficiency and is less likely to damage the tube, making it widely used in certain fields.

Argon arc welding is another important method for producing titanium welded tubes. This method provides good weld formation, stable quality, low investment costs, and simple equipment, making it easier for enterprises to reduce production costs. However, argon arc welding has relatively low production efficiency, and the weld microstructure is a cast structure with a larger heat-affected zone, which limits its application to some extent. Additionally, during and after welding, when the weld temperature exceeds 450°C, protection is required to prevent titanium from being contaminated by gases such as oxygen, nitrogen, and hydrogen. Currently, argon gas is generally used as the protective gas to ensure welding quality.

In summary, both high-frequency welding and argon arc welding have their own advantages and disadvantages. The choice of welding method depends on specific product requirements and production conditions.
