Plug welding hole at the end of pin

[millimeters]

Hello all
Can I apply ASME B&PV sec IX procedure (6010 & 7018) to fill up 1/4" hole at the end of 1/5" pin? Kind of plugging the hole to prevent corrosion. Sketch of pin is attached.
Thanks!

As far as my knowledge goes, this configuration of welding is non-standard as per Sec-IX. It will be difficult to ensure complete fusion and removal of slags. Alternative suggestion is use properly fitting 1/4"x20 plug and seal weld at top.

You didn't get an actual answer, to a question that contained no context.
Where is the finished part going to spend the rest of its life?

Be very careful about your sketch: The question asks about a 1/4" hole in a 1/5" "pin" - but as-drawn, the pin looks like 3/32 (or smaller!) hole less then 1/4 inch in a relatively long 3 inch tapered dowel. But the dimensions call for a 1/4 inch tapped hole 0.75 inch deep in a 0.50 diameter dowel less than 2.0 inch long top of the dowel!

The recommended seal weld around the 1/4-20 NC tapped hole allows less than a 1/8 inch fillet around the 1/4 inch plug Does the dowel (pin) need to be removed later? What kind of alloy is the pin - this will control what kind of set screw and weld is allowable/needed.

Material is A36 and the tapered side of the pin is fillet welded on the distribution gas pipeline to abandon the service (100 psi max) using an in-service welding procedure. The sketch is not to scale. I am not considering plugging 1/4x20 threaded hole on top of the pin an in-service weld.
