How Does Laser Beam Welding Work: A Practical Guide

Laser welding might sound high-tech—and it is—but it’s also becoming a super practical tool for welders who want fast, clean results. Whether you’re working in a fabrication shop or tinkering in your garage, these machines can seriously upgrade your workflow. What’s Actually Happening When You Laser Weld? A laser welding machine uses a concentrated beam—usually…

How Does Ultrasonic Welding Work? A Quick Look at This Clean, High-Speed Method

Ultrasonic welding is one of the fastest, cleanest ways to bond materials—especially plastics and thin metals. It skips the open flame, molten puddles, and filler wire. Instead, it uses high-frequency sound waves to create friction and heat between two materials, fusing them in seconds. This method is widely used in manufacturing for things like electronics,…

Close-up view of a cold welding machine joining two cylindrical metal rods, with copper clamps applying pressure and a red power button visible on the control panel in an industrial workshop setting.

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…
