[MW:9830] WELDING PROBLEM

Dear All,

Presently I am working in a cross pipeline project, an unexpected problem has occurred during the production,due to which the welding had to be stopped,but there is 19 joints which has completed only the (root + hot-pass),still there is (Filler 1 + Filler  2 + Capping) balance and the joints has been left open for more than 48hrs.

My doubt is, if I want to resume the welding now ,whether I have to cut out all the 19 joints and re-weld  ? 
or
Should I reheat and resume with the welding.?

If the joints has to be cut out where is it mentioned so (any applicable code)

The Pipe is = API 5L -Gr.X65 
Electrodes are E6010 (Root) and E7010(Filler+ Capping)
Code : API 1104.


Kindly please suggest your expert advices on this issue.

Thanking You,

Eldho Isaac.
