Welding aluminum
Selecting an appropriate filler alloy for welding aluminum differs from selecting a filler alloy for welding steels. In the case of steel, selection is primarily a matter of matching the tensile strength of the filler metal to that of the base alloy. For aluminum, many variables come into... Read more...

Understanding transfer modes for GMAW
The gas metal arc welding (GMAW) process uses four basic modes to transfer metal from the electrode to the workpiece. Each mode of transfer depends on the welding process, the welding power supply, and the consumable, and each has its own distinct characteristics and applications.
Several... Read more...

Filler metal product approvals
At one time or another you've probably browsed the contents of a filler metal specification sheet. Listed, of course, is the standard data—available wire or electrode diameters, product characteristics, features and benefits, operating parameters, and shielding gas requirements. In short,...

8 FAQs about orbital FCAW
Mechanized, or orbital, gas tungsten arc welding (GTAW) of pipe was first introduced about 40 years ago, largely in response to the need for high-quality welds, repeatability, and zero defects for the large number of nuclear power generator plants being constructed at that time. Weld-out time... Read more...

Welding ASTM A514 or A514M-05 steel?
Cost and efficiency dictate manufacturing and fabricating trends in most industries. In addition to implementing lean work flow practices—better, faster transportation and processing and minimal inventory—many companies turn to the use of higher-strength, lighter-weight materials to reduce...

Drive fast, weld right
"Drive fast, turn left" may be a popular motto among race car drivers, but motorsports fabricators have their own: "Drive fast, weld right." A successful racing team is the sum of its parts, from the fabricators to the painters to the drivers. One of the most critical components is welding,... Read more...

Aluminum pipe pioneer streamlines tube mill welding
Hastings Irrigation Pipe Co., Hastings, Neb., blazed a trail in the late 1940s by manufacturing irrigation pipe out of a material that was not used commonly at that time: aluminum. Five decades later Hastings and that unusual material are both field-tested and proven for manufacturing... Read more...

6 steps to successful brazing
A brazed joint basically can "make itself"—capillary action, more than operator skill, ensures filler metal distribution into the joint. The real skill lies in the design and engineering of the joint, but even a properly designed joint can turn out badly if you don't follow proper... Read more...

The need to feed aluminum
Aluminum, especially thin-gauge, presents unique welding obstacles. Gas metal arc welding (GMAW) in particular presents challenges in wire feeding and selecting the right type of filler metal and equipment. However, several options can aid in effective aluminum welding. In its pure form,... Read more...

Finding direction for the welding industry
In some ways, the welding industry is almost entirely in a class of its own. As far as manufacturing job prospects go, the welding industry is in a minority because it's expected to experience job growth—albeit average—through 2012. Boilermakers, for example, have dimmer job... Read more...
