Abstract
A system for manufacturing a drive shaft assembly comprises a welding apparatus configured to weld a tube to an end fitting to form the drive shaft assembly having an annular weld. A transport apparatus is configured to transport the drive shaft assembly away from the welding apparatus. A knurling apparatus receives the drive shaft assembly from the transport apparatus. The knurling apparatus is configured to knurl the weld of the drive shaft assembly. The knurling apparatus includes a pair of knurling plates having textured surfaces in facing relationship. One of the knurling plates is configured to move relative to the other of the knurling plates to roll the drive shaft assembly between the textured surfaces, thereby knurling the weld to improve an appearance and texture of the outer surface of the drive shaft assembly.
