Solving the mysteries of the fin pass—Part 1

April 10, 2003

By:

The fin pass was not the first time your father gave you five bucks for your allowance. The fin passes are those forming passes that immediately follow the breakdown or initial forming stages on a tube mill. Their role is paramount in the successful final presentation of the formed tubular section to the welding process.

Making the connection

April 10, 2003

By:

Hundreds of types of machined end connectors are used to transmit fluid in fabricated tube and hose assemblies. In recent years manufacturers and end users of these connectors have been developing new methods and processes that eliminate machined connectors and the associated joining operation. Eliminating connectors and joining operations can help save both money and time.

Gauging difficult parts at the press brake

March 27, 2003

By:

Gone are the days when engineers and draftsmen slaved for hours over drafting boards with a pencil and slide rule in hand (does anyone remember slide rules?). Today we've moved beyond slide rules and even beyond hand-held calculators to personal computers and mainframes to do much, if not all, of our design work. CAD and CAM software has made this possible.

A different battlefield, the same strategy

March 27, 2003

By:

The war in Iraq is giving the world a firsthand look at modern warfare and its latest weapons. Embedded reporters and military experts give us blow-by-blow details and explain strategies, logistics, aircraft, weapons, and other tools of war. While war coverage and weapons have evolved since previous wars, the basic strategies remain the same, and these same strategies have found acceptance in business.

Fill 'er Up

March 27, 2003

By:

Hydroforming is gaining ground in the manufacture of many automotive components,such as pillars, frame rails, and engine cradles. Automakers are finding hydroforming advantageous for forming many smaller parts also. The process is useful for manufacturing an automobile fuel filler tube, which is the expanded portion of a fuel filler assembly where a fuel nozzle is inserted.

Specifying the sulfur content of 316L stainless steel for orbital welding

March 27, 2003

By:

The widespread use of autogenous (fusion) orbital gas tungsten arc welding (GTAW) in the high-purity semiconductor and biopharmaceutical industries, combined with modern steel refining technology, has made it both desirable and practical to supply type 316L stainless steel with a restricted range of elemental sulfur.

The basics of roll form tooling design

March 27, 2003

By:

You can successfully roll-form a profile more than one way. In fact, many roll form designers take different approaches to design and development. Also, because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables, many roll form designs are one-of-a-kind; therefore, theory can go only so far.
