I’m seeking guidance on the best techniques for welding copper bus bars to aluminum battery tabs for my current project. Given the different properties of these metals, I want to ensure a reliable and efficient connection.

I am looking for any insights on the following:

• Recommended welding process
• Key considerations for dissimilar metal welding
• Tips for preparing the surfaces and post weld treatment
• Considerations for material thickness and joint design
• Any tips for optimizing weld quality and minimizing distortion
