Note: Flash butt welding is used for rails, rebar, and structural sections. Material is consumed during flashing and upset phases.
Reference
Flash Butt Welding:
Flashing distance ~ 1.0 x section width (carbon steel)
Upset distance ~ 0.5 x section width
Current density: 20-35 A/mm2 depending on material
Total loss = flash distance + upset distance
