Practical guides for selecting welding consumables, understanding AWS classifications and solving material-specific welding challenges.
Why does a low-temperature weld pass tensile test but fail the Charpy impact test? Learn how welding wire selection, weld toughness and temperature affect low-temperature steel welding performance.
Can ER80S-Ni2 replace ER80S-Ni1 for low-temperature steel welding? Understand the differences in nickel content, toughness requirements and filler metal selection before substitution.
Why does a high-strength weld have good tensile strength but poor ductility? Learn how to check weld metal properties, hardness, welding conditions and filler metal selection .
Why does a high-strength weld fail bend testing? Learn how to interpret face, root and side bend results, identify possible defects and check specimen preparation before changing welding consumables.
Can ER100S-G replace ER110S-G? Check required weld strength, product test data and WPS/PQR requirements before substituting high-strength welding wire.
Is higher-strength welding wire always better for high-strength steel? What should you check before upgrading filler metal?
Which welding wire should you choose—ER80S-D2, ER90S-D2, ER100S-G or ER110S-G? Compare strength, toughness and application requirements before selecting the right grade.
Can ER80S-D2 be used for high-strength steel? What should you check first—base-metal strength, toughness, AWS classification, WPS/PQR, or application requirements?
Can ER70S-6 be used for P22 steel? Learn why ER70S-6 is not normally recommended and what to check before using it for P22 welding.
Can ER80S-B2 be used for P22 steel? Compare ER80S-B2 and ER90S-B3 and learn when B2 can or cannot replace B3 for P22 welding.
