The weldability of steels depends on its hardenability.
In general, the higher the hardenability, the lower the
weldability. Weldability can be evaluated theoretically by
use of the PCM value calculated according to:
PCM = C + Si/30 + Mn/20 + Cu/20 + Ni/60
+ Cr/20 + Mo/15 + V/tO + 5B.
Pcm is an acronym for critical metal parameter; it is related to equivalent carbon content in iron alloys.
Powertrain Control Module - 1995 and newer the PCM is mounted in the firewall on the passenger side - visible from the engine compartment
PCM => Powertrain Control Module, AKA the engine computer.
