Welding torch fire hazard

Preventing torch fires in welding and cutting operations

July 15, 2008

By:

Welding and cutting, which accounts for 1 percent of structure fires and 4 percent of nonhousehold property damage, is the most dangerous type of hot work, according to the National Fire Protection Association (NFPA). Companies that weld and cut should take specific steps to increase safety and minimize the risk of torch fires. Hot work, by its nature, has a lot of hazards. Companies and their hot-work operators can protect their safety and their facilities by keeping combustibles away from welding and cutting operations; using new safety features; staying aware of conditions; and knowing and following instructions provided on the precautionary labels and in OSHA, ANSI, and NFPA standards.

CAD system CNC tube bending

From the CAD station to the production floor

July 15, 2008

By:

Conventional tube bending data, regardless of format, is entered manually and therefore susceptible to errors. A modern approach involves using a CAD system to generate a STEP file, which the CAD program exports directly to the bending machine. This method is fast and eliminates errors. The drawback is that such a system requires additional database management efforts.
