Technician A is correct because some exterior body panels, such as quarter panels or fenders, are designed to be replaced at the factory seams. This allows for easier installation and a more seamless appearance. 
Technician B is also correct because the size of the root gap needs to be determined by the metal thickness where the weld is being made. This ensures proper fusion and strength of the welded joint.
