Which of the following electrodes falls into the flat and horizontal welding position category?

Concept:

Coding of Electrodes

It consists of the following letters and numerals and shall be followed in the order stated:

a) a prefix letter 'E' shall indicate a covered electrode for manual metal arc welding, manufactured by extrusion process

b) a letter indicating the type of covering

c) first digit indicating the ultimate tensile strength in combination with the yield stress of the weld metal deposit

d) second digit indicating the percentage elongation in combination with the impact values of the weld metal deposited

e) third digit indicating welding position(s) in which the electrode may be used

f) fourth digit indicating the current condition in which the electrode is to be used

From the chart, it is clear that the third digit i.e. 2 is for the flat and horizontal welding position category, so option 4 is the correct answer.
