Rivet Guide: What Is a Rivet and How to Remove Rivets Properly

Rivets are one of the oldest and most reliable methods for joining metal parts. Even with modern welding and adhesives, riveting continues to be valued for its simplicity, strength, and consistency — especially when heat or distortion must be avoided. But what is a rivet, and how does it function in sheet metal assembly? A rivet is a cylindrical fastener with a head on one end and a tail on the other. When inserted into aligned holes, the tail is deformed using a riveter, creating a permanent mechanic......

How to Avoid HAZ in Sheet Metal Laser Cutting: Pro Tips for Precision

Laser cutting is a go-to method in modern fabrication thanks to its speed, precision, and ability to handle complex geometries. But like all thermal cutting processes, it comes with an often-overlooked challenge, the HAZ, or heat affected zone. If you're cutting parts from thin or sensitive metals, that small area of unwanted thermal distortion can make or break your results. So, what is the heat affected zone, and how do you avoid it during laser cutting of metal sheets? In this guide, we’ll explain ......

9 Sheet Metal Cutting Problems and Solutions

Ask any metal shop foreman, and they’ll tell you, cutting is where problems start if your setup isn’t dialed in. Burn marks, warped sheets, rough edges, and mismatched dimensions don’t just mess up the part, they snowball into delays, rework, and scrap loss. Whether you’re using a high-powered sheet metal cutting machine, a CNC system for metal cutting, or precision laser cutting, one small parameter off can mean the difference between a clean cut and a ruined sheet. In this guide, we’ll break down 9 ......

Common Defects in Sheet Metal Bending and Forming (with Solutions)

Bending and forming sheet metal sounds simple, until your part cracks, wrinkles, or shows up two degrees off. Suddenly, you're staring at a reject pile and wondering what went wrong. Sheet metal bending defects are more common than most shops admit, and the same goes for flaws during forming. Whether it’s springback, surface damage, or a miscalculated angle, these problems don’t just mess with appearance, they compromise fit, function, and cost. In this guide, we’ll break down the most common sheet me......
