Consumables Corner: The thought process behind changing a weld process

June 13, 2014

By:

Q: Our company is using 0.045-in.-dia. mild steel solid wire for GMAW with 90 percent argon/10 percent CO2 shielding gas. A majority of our base metal is ¼ to 1 in. thick welded out of position about 30 percent of the time. We are considering a change in our welding process to reduce lead-times....

Consumables Corner: Tackling root penetration problems

June 12, 2014

By:

Q: We are experiencing weld root penetration issues in our single- and multipass welds. Our base metal is A36, and we oxyfuel-cut it in thicknesses from ½ to 3 in. Most of the weld joints are standard T-joints with a few groove joints. We are using a 0.045-in.- dia. E71T-1C/M flux-cored wire with...

Consumables Corner: Examining the root cause of distortion

June 11, 2014

By: , ,

Q: We manufacture hydraulic cylinders. Ever since we changed our shielding gas blend, we’ve noticed a higher level of distortion. Before the change we used a 95/5 blend, but now we use 92/8, which we have documented using a 0.045-in.-dia. filler metal. Would the 92/8 blend run hotter and cause...

Consumables Corner: The reasons for and misconceptions about preheating steel

June 10, 2014

By:

Q: We are expanding our job shop and adding the capability to work with much heavier structures, including considerably thicker materials. Some of these jobs specify high-strength materials and preheating. Some of our welders claim preheating is performed to remove water from the steel. Can you...

Consumables Corner: Defining current density

June 5, 2014

By: , ,

Q: Our company manufactures cylindrical structures, including tanks and smokestacks made from A36 or A572 material. The material is burned to size on a plasma table and mechanically beveled. Process limitations cause gaps in the joints during fit-up. We use a 0.045-in.-dia. solid wire with a 75...

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.
