Robotic Aluminium Spot Welding
The most robust welding solution for AL Resistance Spot Welding !
Aluminium Resistance Spot Welding
Several different types of alloys are used in Automotive, mainly from the 5xxx and 6xxx series. Depending on the applications, they can take the form of sheets, mould castings or extruded strips. They can be used in most parts of bodies, opening elements and battery casings. Various thicknesses and grades can be combined, with or without adhesive, whose use is fast growing to enhance the rigidity of assemblies. Then, in most cases weld is combined with structiral adhesive bonding.
A strong welding current is necessary to weld Aluminium almloys due to their high levels of electrical conductivity, but the welding time is very short (60 to 200 ms). The use of force profile ensure the best weld quality (force increase during squezze and forging).
State of the Art detailed in clear Welding Guidelines
The guidelines are established to support at early stage of the project. It describes how to implement RSW to parts design, how to determine robust welds : defines weld parameters (welding current combined to force profiles), weld stength, type and size of equipment required. In some case additionnal information can be provided, due to specific condition of parts configuration, pairing thicknesses distibution, structural adhesive or any other customized situation : our welding lab experts can support with trials and expertise.
Combining Weld Gun and Controller
Competitive complete work stations, covering part combinations ranges from thin to thick aluminium materials. Full compatibility, Clear and documented behaviour.
- Welding guns – stiff design – servo with force sensor and brake
- IBox controller driving the weld gun : forcel profiles – centralize management of all welding data and parameters.
High reliability & guaranteed performance and compatible with any robot. The full package can include the Robot F-Package, dresser and caps changer.
