Instruction:SLD-70 is a high-strength copper plated welding wire of 700MPa grade, and the
shielding gas is rich argon gas. Due to the presence of an appropriate amount of Ni and Mo elements in the welding wire, during the welding process, the weld seam has beautiful appearance, good toughness, low splashing, and high welding efficiency, which can be used for all-round welding.
