What Is a Cold Welding Machine and How Does It Work?

Cold welding may sound like a contradiction, but it’s a real and powerful process that joins metals without heat. While traditional welding relies on high temperatures to melt and fuse metals, cold welding machines operate under a different principle—solid-state bonding. This technique is used in aerospace, electronics, and specialty manufacturing industries where precision and material…
