FABTECH 2011: Welding (Part Two)
The Big Show exhibited the latest advancements in arc, gas, resistance and laser welding for diverse material joining applications, including sheet metal, pipes and tubes, jewelry, plastics and other exotic materials. Now our Show-in-Site brings some more of those welding systems and related equipment to you!
Mexico’s Manufacturing Continues to Grow
Manufacturing growth is increasing in 2011, with both new and existing companies expanding operations across various sectors, most notably through record-breaking numbers in auto production and vehicle exports.
HOW TO EVALUATE ENTRY LEVEL PLASMA CNC MACHINES
A large market has developed for low cost CNC plasma cutting machines used by hobbyists and homeowners, small welding shops, and even maintenance departments of larger companies to cut precise parts in house without breaking the bank. These machines can provide great performance at even better prices, but make sure they fit your needs. Jim Colt of Hypertherm examines what you need to look for.
Aluminum Welding: The Cost and Cure of Porosity
Porosity can be a problem in aluminum welding. Less than 3 percent by volume passes most industry codes and standards. But go over, and costs build, hour by $50 dollar hour.

Robotic Applications for Cladding and Hardfacing
Competitive pressures cause manufacturers to research advancements in hardfacing and cladding for surfacing applications that can reduce wear over 50 percent and increase production throughput over 30 percent. Selecting the method best-suited to a particular application involves balancing cost against performance.
BECOMING FAMILIAR WITH THE X-FACTOR
Ideal for use when welding boilers, process piping, heat exchangers and other applications subject to high service temperatures for long periods of time, Tim Hensley of Hobart Brothers introduces a formula that helps determine a weld’s resistance to the brittleness that occurs when the weld is slowly cooled through a certain temperature range.
CORROSION OF PIPE WELDS MADE WITH METAL-CORE WIRE
Regis Geisler of Lincoln Electric analyzes the recent occurrence of this situation at a fabrication site, then recommends some remedies for mitigating the effects.
THE WORLD IS NOT FLAT: TIPS TO IMPROVE OUT-OF-POSITION WELDING (Part Two: Stick Welding)
Fabricators often need to weld out-of-position when working with large/heavy weldments and with pipe, which requires adjusting the electrode angle, puddle manipulation, body position and equipment settings. In the conclusion of this two-part series, Ken Alrick of Thermadyne focuses on stick welding mechanics and shows operators the variables that can help them control weld puddle and weld bead profile.
TIG TORCH IMPROVES WELDING PERFORMANCE AND CONTROL ON MULTIPLE MATERIAL THICKNESSES
Ideal for professional or hobbyist welders, these six different TIG torches from Weldcraft, including some with gas valves and flex necks, provide 150 amp DC and 115 amp AC welding capabilities at 60 percent duty cycle and are available with 12.5 ft and 25 ft, one-piece or two-piece cable lengths.
UNIQUE MIG GUN SYSTEM DOUBLES PRODUCT LIFE, REDUCES COSTS
The Double-Life MIG Gun System from Tregaskiss operates at cooler temperatures to minimize downtime and cost for changeover and replacements, and a full-length liner can be installed from the front end of the MIG gun in less than half the time of a conventional liner replacement to further reduce costs.
NO TURNING BACK:
PIPE WELDING SYSTEM KICKS IT UP A NOTCH
Using the PipeworxTM Welding System from Miller Electric, Shinn Mechanical has increased its pipe fabrication quality and productivity with flatter bead profiles, good sidewall tie-in for 30 percent less grinding, and superior weld puddle control – with no wire rejects in over a year.
