MIG
Solid Wire Electrode BA-MIG 312 for MIG/MAG Welding
Classification:
EN ISO 14343-A: G 29 9
SFA 5.9 / AWS A5.9: ER312
Main Application
BA-MIG 312 is a solid wire electrode for GMAW, suitable for welding or surfacing hardly weldable steels. Suitable to weld buffer layers of hard depositions. The excellent mechanical properties and the notch resistance make this wire of general use.
