UP TO THE TEST
This eye-opening case study explores how Arizona handrail fabricator Hot Az Hell Welding and Fabrication put their welding guns from Bernard to extreme tests during an upgrade from stick to the flux-cored process.
THE WORLD IS NOT FLAT: TIPS TO IMPROVE OUT-OF-POSITION WELDING (Part One)
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. The first in this two-part series by Ken Alrick of Thermadyne takes beginning TIG knowledge to an intermediate/advanced level by comparing right and wrong methods of making these adjustments.
REAMER QUICKLY CLEANS AND REMOVES SPATTER FROM THE MIG WELDING NOZZLE
The Tough Gun Reamer from Tregaskiss reduces automated MIG welding expense, speeds set-up and lowers downtime by quickly cleaning and removing spatter.
ALL-IN-ONE WORKSTATION FOR WELDING AND METALWORKING
An affordable workbench from Miller Electric designed specifically for welders has customizable options that make it the ideal welding workbench for both the fab shop and the home shop.
PORTABLE PLASMA CUTTING FOR ON-SITE CONSTRUCTION
Designed for cutting mild steel, stainless steel, aluminum, brass and copper, Tomahawk plasma cutting systems from Lincoln Electric are ideal for on-site maintenance, service tasks, small construction sites, HVAC work, demolition and rental applications.
FLUX-CORED WIRE IMPROVES WELDING QUALITY ON HIGH-STRENGTH STEEL
This wire from Hobart Brothers provides excellent low temperature impact toughness, is ideal for offshore and structural applications, and offers 100 – 110 ksi tensile strength.
MIG WELDING CONSUMABLES REDUCE DOWNTIME IN HIGH HEAT APPLICATIONS
These consumables from Bernard also have a spatter guard improves shielding gas coverage, reduces diffuser wear and “drop in” contact tips change quickly and without tools, all to deliver superior performance.
10 Common TIG Problems and Solutions
Here are some descriptions of common TIG mistakes and basic tips on how to prevent these errors from happening.
Financial Justification: Achieving a Two-Year Payback with Robotic Welding
Deciding whether to convert manual or semiautomatic arc welding stations over to robotic welding is typically driven by the payback or return on investment achieved through labor savings. But Geoff Lipnevicius of Lincoln Electric explains that labor savings do not comprise the total anticipated savings and shows how they are generated from a variety of other process-related areas.
Basic Tips for Understanding (and Preventing) Common Types of Weld Cracking
The best defense against weld cracking is to understand its causes and solutions. And he shows why the best place to start is by understanding hot cracking and cold cracking.
FROM 5G TO 6G: IMPROVING PRODUCTIVITY ON OUT-OF-POSITION PIPE WELDING
Keith Packard and Derick Railling of Hobart Brothers explain how making the change to a tubular wire for out-of-position pipe welding applications can yield significant productivity gains. They also show how to ensure that the chosen wires best match the base material for the application and how to prevent an already difficult task from becoming more so.
LESSONS LEARNED IN GTAW QUALIFICATION TESTING
To emphasize the importance of the effects of welding heat input and cooling rate on weld mechanical properties, Regis Geisler of Lincoln Electric analyzes another application where a one percent nickel electrode was successfully implemented in a welding application.
