Like all arc welding processes, submerged arc welding (SAW) requires the right consumables for the specific application to achieve optimal results. Are cored wires right for yours?
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.

The factors that influence filler metal consumption, such as joint design and the choice of welding process, are key to helping you better understand, anticipate, and monitor operational costs and the bottom line.
Q: We're a midsize job shop that manufactures a wide variety of products from various types of metal. Currently we have a project that requires welding 304L to 316L stainless steel and welding both of these alloys to A572 Grade 50 steel. Some of the welds are structural and some are used in...
