Butt Weld on the pipe process 1 inch

[juncreek]

Dear Piping expert,
On one of the Spec document piping requires for join piping 1" shall use socket welding.
Could anyone advise, the consideration of the requirement.
What is the concern, and consequence of using butt weld.

Thanks for the sharing.

On process piping (High Pressure and Tempreture system) butt weld must be preferred applying GTAW Process,because finished weld joint can be examined by radiography technique.where as on Low Pressure and Tempreture system piping socket weld should be prefferred.

What about if the 1" pipe already done with butt weld. Is there any issue related and mitigation?
Is there any reason cannot doing butt weld.

1" buttweld is better, but requires better welding skills.
