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?

The ramming machine bores into the side of the new automobile at a speed of 50 kilometers (31 miles) per hour. Within a fraction of a second, sensors situated all over the test dummy signal details of the stress load. Shortly afterward the overall results of the Euro-NCAP crash test will appear in all the specialized automobile magazines.
