Welding compacting process

How does work compacting process ?

Compacting in welding refers to the controlled application of force to maintain intimate contact between parts prior to and during the welding operation. This ensures a uniform interface for effective material bonding and minimizes gaps or misalignments.

Thermal processing method applied to stranded conductors, electrical cables, braids with cross-sections ranging from 0.5 mm² to 120 mm², as well as flexible busbars, in order to locally increase mechanical rigidity over a defined section.

This operation is typically carried out as a preparatory step prior to a subsequent assembly or integration process.

Compacting Process Technologies

Several technologies are available for the compacting process, the choice of process dependsl requirements, material properties, and overall project costs.

Depending on technical and production constraints, compacting can be implemented using either resistance welding or ultrasonic welding technologies. The final choice is determined by performance targets, material behavior, and industrialization parameters.

  • Resistance Welding:
    Parts are held between electrodes that apply a defined clamping force. The pressure ensures consistent electrical contact, allowing current to pass through the interface. This results in localized heating and fusion at the joint.

  • Ultrasonic Welding:
    Components are subjected to contact force under a vibrating sonotrode. The ultrasonic energy induces interfacial friction and localized melting, forming a strong metallurgical bond. Proper compacting ensures even energy transmission and uniform weld quality.
