Welding consumables are classified in accordance with basically the mechanical and/or chemical requirements of the standards, excluding such requirements as size, length, marking and identification manners.
Standards for welding consumables are abbreviated as follows:
- JIS: Japanese Industrial Standard
- AWS: American Welding Society’s Standard
- EN: European Norm
- ASME: American Society of Mechanical Engineers Standard
The test conditions of mechanical properties and hardness are as follows:
- Unless otherwise specified, impact values are obtained with Charpy 2mm-V notch specimens.
- Unless otherwise specified, tension test and hardness test are carried out at room temperature.
- Unless otherwise specified, tension test and hardness test are carried out in the as-welded condition.
- The gauge length of tensile specimens is 4 x D (where D is the diameter) for testing at room temperature.
- Unless otherwise specified, postweld heat treatment is followed by furnace cooling.
- Unless otherwise specified, the testing method is as per AWS standard.
- All mechanical and chemical data are given separately as "Example" (one of the manufacturer’s laboratory test data) and "Guaranty" (the guaranty value as per AWS standard). Tensile strength and 0.2% offset strength are rounded as SI unit.
