Dears,
In general, the self life of welding consumables depends on handling and storing
condition. Therefore it is mandatory for end user to understand and implement proper
handling and storing procedures. Handling and storing procedures implemented properly
extends the self life welding consumables.
Welding consumables can be divided in to two main groups, those utilizing flux and
those made of just solid wires. Stick electrodes and flux cored wires fall in to the first
category while GTAW rod, Submerged Arc (SA) wires, and GMAW wires to the second
one.
Each group has its own self life characteristic as stated below:
Group #1 (Stick electrodes, Flux cored wires, SA fluxes)
Self life: 5 – 7 Years (depends on type of flux type)
Group #2 (GTAW rods, SA wires and GMAW Wires)
Self life: Until certain level of rust/oxide occurred on the surface of wires.
Some of welding consumables have already been packed in Vacuum condition,
utilizing aluminized packing. This provides better protection against atmospheric
contaminations during storing and handling hence extends the self life even longer.
