Consumables Corner: Storing stick electrodes

August 21, 2014

By: ,

Q: I recently saw a comment that regular stick electrodes could be overdried in ovens to the point of causing poor weld performance. Is this true? We store all our electrodes, including low-hydrogen, at 135 to 140 degrees F at all times and have not noticed any problems. We are located in Arizona,...

Consumables Corner: Horizontal fillet test troubles

July 1, 2014

By: ,

Q: For a recently acquired large structural job, we have had to qualify a single-pass 5/16-in. fillet using 0.045-in. E71T-9M flux-cored wire. We are having trouble passing the horizontal fillet test. When performing the weld break test on the horizontal fillet weld, there is incomplete penetration...

To infinity and beyond—with the help of a filler metal

May 19, 2014

By:

4943 alloy is the first aluminum filler metal developed in the U.S., designed for use in wrought commercial applications, and registered with the Aluminum Association in over 50 years. It was designed primarily to provide a consistently high-strength alternative to filler metal 4043 while maintaining various advantages of 4043. The most interesting and comprehensive series of third-party tests were conducted by NASA at the Goddard Space Flight Center for the James Webb Space Telescope project.

Choosing the correct gas delivery system for metalworking

September 9, 2013

By:

Supplying gas to your metalworking applications can be complicated, especially if the gas needs to reach multiple locations. If you are looking for cost savings and productivity gains, consider installing gas cylinders at one main location and controlling them with a basic manifold or switchover manifold. With this method you won’t need to worry about cylinders running out of gas.
