"Quality, performance and cost-efficiency in aluminium and aluminium alloy assembly"
The basic principle of resistance welding is the assembly of two metal parts through fusion under force. This process offers considerable user advantages. Whilst all of these advantages have made resistance welding a very widely used process, particularly in the automotive industry, it has up until now, been difficult to use for welding aluminium. Now, with ARO’s technology and know-how, aluminium sheet assembly is an extremely viable option.
Advantages of Resistance Welding
- Cost efficency
- Environmental protection
Resistance welding demands no prior operation requirement, such as primary drilling or assembly of components, and it provides substantial resistance to mechanical stress.
ARO’s unique technology (iBox and servo-actuator with force sensor) manages thermal expansion and ensures formation of homogenous nuggets. Welding force is perfectly synchronized with the welding current; all welding parameters are managed through a single HMI, and can be documented for traceability.
A wide range of high power DC transformers allows manufacturers to apply the principles of resistance welding to almost any aluminium joining challenge, handling welding currents of up to 100kA for stationary applications, up to 80kA for robotic applications, and up to 50 kA for manual applications,
