Resonators producing a high beam quality and small spot size provide a machine tool with a broader depth of field that enables greater process tolerance to material deviation. This tolerance gives the operator a bigger sweet spot for machine parameters to produce consistent, high-quality parts.

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.

Several modes of nitrogen assist gas supply exist, but with choice comes the potential of saddling your business with overhead costs that make it difficult to compete. The best approach is to map out a growth strategy, using each option's performance and value, that coincides with monthly nitrogen usage.

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?

A new 4-kilowatt laser just hit the floor. The technician will arrive on Monday to install it. It's your responsibility to make sure the gases arrive. The preinstallation manual was faxed to your local gas supplier, and all is well.Not so fast. Other gas matters can affect cost and efficiency. The...

Today's job shop market is characterized by unrelenting competitive pressure for laser processing services. Job shops are expanding into niche services such as multiaxis laser processing and thick plate applications to differentiate themselves from their competitors. Others are performing additional services such as forming, welding, painting, and assembly to add value.
