  Superconducting Weyl semimetals present a novel and promising system to
harbor new forms of unconventional topological superconductivity. Within the
context of time-reversal symmetric Weyl semimetals with $d$-wave
superconductivity, we demonstrate that the number of Majorana cones equates to
the number of intersections between the $d$-wave nodal lines and the Fermi
arcs. We illustrate the importance of nodal line-arc intersections by
demonstrating the existence of locally stable surface Majorana cones that the
winding number does not predict. The discrepancy between Majorana cones and the
winding number necessitates an augmentation of the winding number formulation
to account for each intersection. In addition, we show that imposing additional
mirror symmetries globally protect the nodal line-arc intersections and the
corresponding Majorana cones.
