  • Publication number: 20210138591
    Abstract: A wire for gas-shielded arc welding includes, based on a total mass of the wire: C: 0.01 mass % or more and 0.10 mass % or less, Si: 0.05 mass % or more and 0.55 mass % or less, Mn: 1.60 mass % or more and 2.40 mass % or less, Ti: 0.05 mass % or more and 0.25 mass % or less, Cu: 0.01 mass % or more and 0.30 mass % or less, S: 0.001 mass % or more and 0.020 mass % or less, N: 0.0045 mass % or more and 0.0150 mass % or less, Al: 0.10 mass % or less, and P: 0.025 mass % or less, with the remainder being Fe and inevitable impurities. In the wire, the following relationship is satisfied: 0.1?[Ti]/[Si]?3.0, where [Si] is the content of Si (mass %) and [Ti] is the content of Ti (mass %).

  • Publication number: 20190375038
    Abstract: Disclosed herein is an arc welding method including welding a steel sheet while controlling feeding of a welding wire in a moving direction. Welding is performed using the welding wire and a gas containing Ar at a frequency of 35 Hz or more and 160 Hz or less in the moving 15 direction of the welding wire. The welding wire contains C and further contains, in mass %, Si: 0.2% or more and 1.3% or less, Mn: 0.2% or more and 1.5% or less, and S: 0.01% or more and 0.05% or less, with the balance being Fe and inevitable impurities.
