What kind of gas shielded welding wire for Q345 steel plate?
er-49-1 ER50-6（GB / / t8110-2008）
Carbon steel welding wire for Q345 steel using ER50-6 gas shielded welding.ER50-6 is a kind of carbon steel welding wire for gas shielded welding. It has excellent plasticity, toughness and crack resistance, especially low temperature impact toughness.Application: it can be used in various positions of pipes such as manual tungsten inert gas arc welding, grounding and arc welding, and satisfactory welding joints can be obtained. Weldable carbon steels and certain low alloy steels.
Q345 is one of the commonly used low-alloy structural steel grades, and the welding wires matching the strength are: GB ER50-6 copper plated solid low alloy steel welding wire.ER50-6 welding wire is equivalent to American Welding Association AWS's ER70S-6, Japan JIS's YGW12 classification society. In accordance with the classification society (ABS), Bureau Veritas (BV), Chinese Veritas (CCS), Norway Classification Society (DNV), Germanischer Lloyd (GL), Kr (KR), Lloyd's register (LR), ClassNK (NK) as approved by the classification society.The utility model has the advantages of strong oxidation resistance, strong oil stain and small pore sensitivity of the base material. Used for welding of 500MPa grade structural steel parts, including Q345.Can be used as protective gas welding 100 using carbon dioxide gas; can also be used for MAG welding, argon + carbon dioxide gas, mixed gas arc welding.The diameter of the welding wire is determined according to the factors such as the rated output of welding machine, welding current, welding machine load rate and base metal thickness.
