TS EN ISO 2401

TS EN ISO 2401 is a welding consumables standard that defines how to determine the efficiency, weld metal recovery and deposition coefficient of covered electrodes. These three indicators are used together to describe how much of the electrode contributes to deposited weld metal, how much is effectively recovered, and how efficiently the consumable is converted into usable metal in the weld.

What the measured indicators mean

In welding practice, efficiency and recovery are practical measures of material utilisation. They help show how much of the electrode mass ends up as deposited weld metal versus how much is lost through spatter, stub loss, slag or other process-related effects. The deposition coefficient is a related performance indicator used to compare how much weld metal is produced per unit of consumable used. Together, these concepts are important when comparing electrode types and assessing manufacturer data in a consistent way.

Method framework defined by the standard

The scope of this document is to specify methods for determining these values for covered electrodes. In general technical terms, such a standard focuses on measurement consistency rather than on electrode design details. That makes it useful for benchmarking welding consumables under a common approach, especially when material utilisation and process efficiency need to be described in a repeatable and comparable manner.

In practice, TS EN ISO 2401 supports objective evaluation of covered electrodes for technical documentation, product comparison and laboratory assessment. It gives users a common basis for discussing how effectively a coated electrode converts consumed material into deposited weld metal.
