For some time welding was seen as the only way to assure the integrity of joints in particularly demanding load-bearing or high-vibration structures. Not so today.
Historically, many companies manufacturing heavy-duty equipment or fabricating large, metal structures traditionally employed the process of welding joints together. However, today many of them are embracing an alternative to welding in the form of direct-tension installed, swaged lockbolts in the form of the HuckBolt®, manufactured by Howmet Fastening Systems. Star Fasteners are key Huckbolt suppliers and application experts. In this discussion paper, they take a detailed look at the question of welding versus lockbolts.
