1. What is DSAW welding method?
DSAW is the abbreviation of double-side arc welding. This welding method uses the metal to be welded as one pole and the electrode as the other pole. When the two poles are close, an arc is generated, which melts the metal and the electrode to achieve welding. Aluminum alloy AC pulse double-sided arc welding is a type of DSAW. A large number of experiments have shown that this process can increase the thickness of a single weld, reduce heat input and significantly reduce post-weld deformation, and has a good application prospect.
2. What are the characteristics of DSAW welding method?
The single-power double-sided arc welding (DSAW) process composed of plasma arc (PAW) and tungsten arc (TIG) can obtain a weld with a large depth-to-width ratio. This process is characterized by high efficiency and low cost, and is an advanced welding technology. Through numerical simulation technology analysis, it can greatly increase the depth of penetration and improve the performance of the heat-affected zone.
3. What is the difference between DSAW welding method and other welding methods?
Common welding methods such as tungsten inert gas welding (WS) refers to TIG or GTAW, stick arc welding (DS) is SMAW, and DSAW is double-sided arc welding. Compared with traditional single-sided welding, DSAW can increase the thickness of a weld, reduce heat input and significantly reduce post-weld deformation; compared with some single arc welding methods, it can obtain welds with a larger depth and width.
4. What materials are suitable for DSAW welding method?
The double-sided arc welding process of aluminum alloy AC pulse is an application of DSAW, indicating that DSAW is suitable for welding aluminum alloy materials. In addition, for stainless steel, there is also a DSAW application such as stainless steel PA-GTA double-sided arc welding process, so DSAW is also suitable for welding stainless steel materials.
5. What are the application fields of DSAW welding method?
Since welds are usually used to connect the components or parts of steel structures, and DSAW can improve welding quality and reduce deformation, it may be used in the field of steel structure construction, such as large factories, venues, and super high-rise buildings. At the same time, this advanced welding method may also be used in high-precision manufacturing fields that require high welding quality and deformation control, such as automobiles, ships, aircraft, high-speed railways, etc.
