Appearances across the corpus
Applications of inertia welding abound in the trucking industry. One of these is the fabrication of trailer brake cams by Rockwell [?]. Formerly forged in one piece, the cams are now inertia welded on a Model 250 machine at a rate of 60 per hour, reducing forging inventory and cutting part costs by 24%.
