The purpose of welding a square nut is to provide a secure and stable connection point for bolts or threaded rods. Square nuts have four sides that provide more surface area for a better grip and can resist loosening or rotation compared to hexagonal nuts.
Welding a square nut onto a workpiece can be particularly useful in situations where the nut needs to be fixed in place or where there is limited access to the backside of the workpiece. It can also be used to attach threaded components to materials that cannot be drilled or tapped directly.
Overall, welding a square nut can provide a strong and durable connection point, particularly in applications where other fastening methods may not be suitable or available.
