1. Scope This standard covers the properties of arc-welded portions of automobile parts. "Arc welding" (hereinafter referred to as "welding") is defined later. Provisions in the standard do not apply if design drawings, or equivalent documents (e.g. Technical Instruction Sheets) contain special provisions on welding. The standard does not cover portions welded for reasons related to production process (e.g. temporarily welded portions). If sections made of * * high-carbon steel , alloy steel , or carburized steel are to be welded, the design, production technology and other departments concerned shall discuss issues related to material properties (e.g. hardnes s at heat attack zone etc.), before applying the standard. Remark: *: Material with a carbon content of 0.3 mass% or more 1.1 Welded Materials Materials specified in TSG3100G, TSG3101G, TSG3103G, TSG3107G, TSG3108G, TSG3109G, TSG3111G, TSG3113G, TSG3150G, TSG3153G, TSG3154G, TSG3155G, TSG3200G, TSG3211G, TSG3220G, TSG3242G, TSG3290G, TSG3580G, TSG7200G, TSG7202G, TSG7203G, and TSG7207G; and equivalent materials

1.2 Welding Method Object welding methods comprise CO2 arc welding, MIG welding, MAG welding, TIG welding, plasma welding, and shielded metal arc welding. However, arc spot welding via these methods is not covered by this standard. Remark: This standard covers processes and product manufacturing. manufacturing. It does not cover various loads applied to vehicle welded sections in the market. It is allowable that individual individ ual cross sections of welded portions do not meet the standard, if the portions can bear design loads by maintain ing part of required characteristics.
