Throat cracks typically appear as relatively _, _ cracks along the centerline of the weld.

Throat cracks form along the weld centerline where the cross-section is smallest and cooling stresses are concentrated. Once such a crack initiates in the weld throat, it tends to propagate straight along the length of the bead under restraint, yielding a long, straight fracture path. That makes “long and straight” the best description. Short or curved cracks would suggest different cracking modes or irregular geometry, not the typical centerline throat crack.
