2. What nuts can I weld?
There are various types of weld nuts that can be welded, including round weld nuts, square projection weld nuts, tab spot weld nuts, tab projection weld nuts, hex-3 projection weld nuts, hex-6 projection weld nuts, flange weld nuts, stamped flange weld nuts, and floating cage weld nuts. These different types of weld nuts offer versatility for different applications.
3. How strong are weld nuts?

4. Can you weld regular nuts?
Regular nuts, such as structural nuts or those with high carbon content, are generally not recommended for welding. Structural nuts gain their strength through heat treating and should not be welded. Non-structural nuts are often made from steel that is not weldable due to its high carbon content.
5. Are welds as strong as bolts?
Welded joints are typically stronger than bolted joints. Welded joints do not have the perforations needed for bolted joints, resulting in higher strength. The manufacturing process plays a significant role in joint strength, with bolted joints offering simplicity, but welded joints providing superior strength.
