Environmental Impact of SMAW vs GMAW

Basics

• May need a better name, but:
• This page aims to determine the environmental impact via looking for existing / making a rudimentary LCA of the equivalent Consumables needed for Shielded Metal Arc Welding ( and the similar Flux Core Arc Welding and Submerged Arc Welding Processes) vs Gas Shielded Arc Welding / Gas Tungsten Arc Welding
• IE Stick Welding vs MIG/TIG Welding

Flux

• Chemistry is Life - Chemistry of a Welding Rod (shitty article, may be able to grab more from it's guts later)
• Weldwire . net Products - E7018 AWS: A5.1 (Lists standards for chemical deposits/composition / whole, not much specifics on ingredients)
  • Attatched PDF of a MSDS / MDS from the above source, page 2 "Section 3" of is titled "COMPOSITION/INFORMATION ON INGREDIENTS"
