How long must carbon steel electrodes be baked according to CSA standard W48?

Explanation:
Moisture control in electrodes is crucial because moisture inside or on the coating can release hydrogen during welding, leading to porosity or hydrogen-induced cracking. CSA W48 specifies that carbon steel electrodes must be baked to remove this moisture before use. The required bake time is two hours, typically at about 250°F (120°C). This duration ensures sufficient moisture removal so weld quality isn’t compromised. Shorter times wouldn’t fully dry the electrodes, while longer times aren’t necessary for this standard.
