气体保护焊用镀铜焊丝

COPPER-COATED SOLID WELDING WIRE

XCJ 50-2符合GB ER50-2 AWS ER70S-2

说明 DESCRIPTION

XCJ 50-2是一种多用途的碳钢焊丝，得益于锰、硅和钼元素的精确配比，焊接成品具有优良的韧性和抗裂性。XCJ 50-2焊丝特别适用于需要高强度和良好韧性的焊接，如修理工作、建筑业和重型机械制造。其优秀的焊接性能表现在稳定的电弧和较低的飞溅，确保焊缝平滑且外观整洁。这种焊丝也非常适合用于细微或复杂的焊接工作，提供精细的焊接控制和优异的焊缝质量。

XCJ 50-2 is a versatile carbon steel welding wire with a precise mix of manganese, silicon, and molybdenum, ensuring excellent toughness and crack resistance in welds. Ideal for high-strength and toughness-demanding tasks like repairs, construction, and heavy machinery manufacturing, it offers a stable arc and low spatter for smooth, high-quality welds. Perfect for intricate welding, it allows for precise control.
