Like an extrude or revolve, a sweep is a tool for modeling a 3-D shape. A sweep consists of three basic elements--a profile, a path, and a set of rules for "sweeping" the profile along the path. A sweep can be a powerful tool when modeling 3-D shapes, according to columnist Gerald Davis.

Woolf Aircraft Products Inc. developed an inspection tool that can beused to measure a leg length, as well as the actual throat of a weld.Using these two known measurements, quality assurance personnelthen can determine the actual size and the convexity and concavity ofa specific fillet weld.

Vision technology adds flexibility and intelligence to the robotic welding cell.

Ultra Tool & Manufacturing launches a program to tackle sensor technology in an effort to errorproof the pressroom.

Crimson Fire, a lean fire truck OEM, enjoys record orders, but prepares for challenges ahead.

This technical article from TRUMPF takes a look at how parts can be redesigned to include less material and to be processed much more efficiently.

Tough economic conditions have hit the construction industry as hard as they have many other industries. These problems in commercial construction are affecting structural steel fabricators. New technologies are especially benefiting four important structural steel fabricating processes by reducing labor costs. These represent some of the bigger developments in recent years.

From weld resistance to factor 1, sensors employ technology to deliver accurate, long-lasting operation, even in challenging welding environments. When properly applied, these systems reduce downtime and replacement costs while optimizing production.
