Q: We manufacture various products for the agriculture and transportation industries. A majority of our products are made from 6061 and 5652 aluminum and are joined with gas metal arc welding (GMAW-S) using a 5356 filler metal and 100 percent argon shielding gas. Most of the joints are partial...

Q: We need to weld a 1-in.-thick AISI 1050 carbon steel plate to a 2-in.-dia. A514 steel shaft. The AISI 1050 has a yield and tensile strength of 95 KSI and 115 KSI, respectively. We know we should preheat, but we're unsure of what temperatures to use or what filler metal to select. Could you...

Argon and CO2 are the most commonly used gases in gas metal arc welding (GMAW). Alone, each has pronounced advantages. Together they combine to neutralize each other’s weaknesses and capitalize on each other’s strengths, all while providing you with your desired weld requirements.

Q: We're a construction equipment manufacturer that is finding that our customers increasingly require more components designed and manufactured from high-strength steels such as A514 or 4130. This means we have to preheat and follow slow cooling conditions, but even then certain joints or...

Q: We manufacture stainless steel tanks used in various industries and we aren’t always informed of service conditions and chemical exposures. We would like to reduce or minimize the number of filler metals we use to cut down on costs and prevent accidental use of the wrong filler metal. The...

Q: We are a bridge and structural steel manufacturing shop that uses a mixture of common base materials such as A36, A572, and A992. Recently we’ve been experiencing sporadic centerline cracks in the root passes of fabricated I-beams that we weld with flux-cored arc welding (FCAW). Oddly enough,...

Q: We manufacture structures for the utility industry and primarily weld A36, A572-Gr. 50 and A871-Gr. 65. Recently we converted some of our welding processes to higher-deposition submerged-arc welding (SAW) but are concerned about the amount of heat we are adding from welding. What is the...

Low alloy steels gain their mechanical and chemical properties from the addition of alloying elements, including nickel, chromium, molybdenum, and manganese. They typically offer an ultimate tensile strength of 80,000 PSI or greater, and as with any material, they require a filler metal that matches their chemistry and provides the desired strength.
