The automation characteristic of friction stir welding (FSW) is one of its core advantages. Through precise mechanical control and programming, the stirring probe can weld along predetermined paths and according to set parameters, reducing the impact of human factors on welding quality. This not only enhances the stability and repeatability of product quality but also reduces reliance on highly skilled technicians, addressing the issue of a shortage of skilled talents in the manufacturing industry. After introducing FSW technology, AMTD leveraged its automation features to standardize the welding process, significantly improving the stability of product quality while reducing dependence on experienced welders.
In terms of environmental protection, the welding process of FSW is characterized by the absence of radiation, fumes, and low noise, aligning with the global trend towards green development in manufacturing. As environmental regulations become increasingly stringent, traditional welding methods face growing pressure, while the environmental advantages of FSW give it a competitive edge in the market. For instance, in production workshops with high environmental requirements, such as those in the food processing equipment manufacturing and medical device manufacturing sectors, FSW holds broad application prospects. AMTD actively responded to the call for environmental protection by adopting FSW technology in production, not only meeting environmental requirements but also enhancing its corporate image and market competitiveness.
From the perspective of application scope, FSW is not limited to shaft-type components and can be used for butt and lap welding of flat plates, greatly broadening its application areas. In shipbuilding, FSW can be employed for welding large hull plates, improving welding efficiency and quality while reducing the weight and deformation of the hull. In the rail transit sector, using FSW for vehicle body welding can enhance the strength and sealing performance of the car body, improving the operational safety and comfort of trains. AMTD is also exploring the application of FSW in more fields, such as in the welding of components for semiconductor manufacturing equipment, utilizing the high precision and environmental-friendly characteristics of FSW to enhance product quality and production efficiency.
However, FSW also faces some technical bottlenecks. For example, the issue of stirring probe wear: due to the high stress and temperature variations experienced during high-speed rotation and friction, the service life of the stirring probe is limited, necessitating frequent replacements and increasing production costs. Additionally, the welding speed and effectiveness of FSW for some high-melting-point materials require further optimization. In response to these issues, AMTD is collaborating with research institutions to conduct optimization studies on stirring probe materials and processes, aiming to break through technical bottlenecks and promote the further development of FSW technology.
