ESAB Acquired by Colfax Corporation
A leader in the pump and fluid handling business acquires a popular welding brand.
2012 State of the Industry: Robotics
Forecast: Very strong opportunities to expand into job shops and smaller manufacturers, along with continued strength in the traditional automotive, agricultural, heavy equipment and aerospace sectors.
2012 State of the Industry: Welding
Forecast: Look for modest increases in oil and gas, agriculture, mining, railroad, transportation, defense as total system solutions get new talent up to speed as quickly as possible, focus on shorter ROI, and are customized by industry needs.
TIPS FOR OVERLAYING JOURNALS AND CASTER ROLLS
Although the ultimate hardfacing deposit selected will vary based on the intended application, Regis Geisler of Lincoln Electric explains the welding and fabrication techniques to follow for rebuilding caster rolls, crankshafts, roll pins, extrusion rolls, crusher rolls, or other types of journals made of low alloy steel.
ROOTING OUT RESISTANCE: ELIMINATING THE HIDDEN VARIABLE
Resistance is frequently characterized by random and intermittent welding issues that are difficult to repeat. But even though resistance-related problems can have many symptoms, their root cause is always the same – not enough current is flowing in the electrical circuit. Nick Petersen of Miller Electric shares some tips on how to pinpoint and root out this frustrating problem.
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.
