1. A downhole tool, comprising:
a first member, the first member having a first member inside diameter (ID1), a first member outside diameter (OD1), a first member thickness (t1), and a first member hardness value (HV1);
a second member, the second member having a second member inside diameter (ID2), a second member outside diameter (OD2), a second member thickness (t2), and a second member hardness value (HV2) the first and second members positioned proximate one another forming an overlapping space therebetween, wherein the first member forms at least a portion of a v-block of a multilateral junction and the second member forms at least a portion of a multilateral mainbore leg or lateral bore leg;
a crack compliant seal positioned at the overlapping space, the crack compliant seal having a compliant seal hardness value (HVcs) less than or equal to one or more of the first member hardness value (HV1) and second member hardness value (HV2); and
a high yield strength weld positioned at the overlapping space, the high yield strength weld having a yield strength of at least 50 ksi.
