Improving blank edge conditions
Blanking—like piercing, parting, notching, and trimming—basically is a shearing process. Sheet metal that is sheared undergoes a predictable process and yields a predictable cross-sectional profile. Typically during shearing, as the punch initially engages the sheet metal, it... Read more...

Al GMAW: CC or CV?
I've read that constant-current (CC) power supplies are preferred for gas metal arc welding (GMAW) aluminum, but when I visit companies that sell welding equipment, they tell me I want a constant-voltage (CV) power supply. What's the real story? Can I use the more common CV power supplies or... Read more...
