What is the difference between ER70-G welding wire and ER100S-G welding wire?
ER70-G is the GB standard, and ER100S-G is the AWS standard. ER70-G is equivalent to AWSER100S-G, and they can be substituted for each other.ER70-G welding wire and ER100S-G welding wire are all 690MPa grade high toughness low alloy steel gas shielded welding wire. It is rich in argon gas protection, and has good all position welding process performance. Soft arc, small splash.ER70-G welding wire and ER100S-G welding wire use: suitable for welding 690MPa grade high strength steel structure, such as construction machinery, lifting machinery, bridges, pipelines, ships and pressure vessels and other structures welding.
Generally there are three kinds of welding wire:(1) MGS-70 ER100S-G is used for welding 690Mpa high strength steel(two) MG-80 ER110S-G is used for welding 780Mpa high strength steel(three) MGS-88A ER120S-G is used for welding 780Mpa grade high strength steel at low temperatureMG70-G conforms to GB ER70-G, equivalent to AWS ER100S-G1. note: JQ.MG70-G is NiMo type 700MPa high toughness low alloy steel gas shielded welding wire, with good welding performance in all position. Arc stable, small splash.2. uses: suitable for welding 700MPa grade high strength steel structure, such as construction machinery, lifting machinery, bridges, pipelines, ships and pressure vessels and other structures welding.3. wire chemical composition (%):C = 0.10, Mn1.40~1.80, Si 0.50~0.80, S = 0.025, P = 0.025, Cu = 0.50, Ni1.20~1.60, Mo0.30~0.60, Cr, 0.15~0.25, Ti = 0.10.
Ask GB ER70-G is different from AWS ER100S-G.GB T 8110-2008 gas shielded arc welding with carbon steel, low alloy steel wire, only ER69-1, ER70-G is everyone's customary name, there are many manufacturers also have this as a product brand. Simply put, these two are tensile strength greater than 690Mpa welding wire.
