You will need to make sure the WPS you use was qualified on API 5L-X70 material per API 1104, 184.108.40.206 "When welding materials of two separate material groups, the procedure for the higher strength group shall be used".. Same for the repair WPS if you qualify them separately.
Yes you can weld them with conventional welding processes. The filler metal strength can either be matched to the higher strength or lower strength...thanks for looking into this, what are the codes that specify the methods you stated above? for example i know that B31.8 I-1.1(c) states to match...The Codes do not specify a particular strength filler metal for use, that is left up to the engineer of record and acceptable qualification of a WP...1What's the required Code?
