It takes two, baby
Hybrid laser-arc welding (HLAW) is not a new concept, but it has gained in popularity recently. Faster travel speeds, less heat input and distortion, and higher tolerances make HLAW a great alternative to laser welding or arc welding processes alone. The most common combination is laser and...

Improving manual plasma cutting quality
If you're maintaining the proper travel speed, the sparks will exit the workpiece at a 15- to 20-degree angle.
Plasma cutting is easy to learn, and cutters are simple to use. In fact, it's so easy that many users go right to work as soon as they remove the unit from its packaging.... Read more...

Can your manufacturing software do this?
Software has changed the nature of fabricating. Most fabricating shops hammer out the manufacturing details of a job on their own computer-aided manufacturing (CAM) software packages immediately upon receipt of the customer's engineering drawings. Some of the more aggressive fabricating shops... Read more...
