Do your welds pass muster?

November 25, 2008 | By Richard Green

For a job shop or manufacturer, maintaining weld quality begins with consistent shielding gas in the gas metal arc welding (GMAW) process. Consistently delivering the correct blend ensures proper arc characteristics and weld quality. Mixing technology, supply gas density, and gas usage patterns can affect the on-site gas blending system's ability to deliver a consistent blend.

Combining 2-D and 3-D laser applications

October 10, 2006 | By Richard Green

Laser equipment specialists claim that an operator now can change the head for cutting up to 3/4-inch mild steel to welding 3-D parts in less than 15 minutes. So the laser cutting/welding equipment has made a technological leap to support the job shops looking to expand their capabilities. But how have the gas systems evolved to support these advanced capabilities?
