Wave soldering does not form a brittle intermetallic phase

Solder contacts between cells are more economical and reliable than screw contacts or double metal busbars. However, it is technically difficult to weld aluminum-copper contacts for surge protection because the greater the difference between the two metals, the more likely the resulting welded joints are to be cracked, a problem often encountered with conventional laser welding.
