S190 钴基堆焊焊丝

钴基堆焊焊丝与钴基堆焊条焊芯相同,特性及用途也与钴基堆焊焊条一样,即该合金焊丝具有良好的红硬性,在600℃以上仍能保持较高的硬度及良好的耐磨、耐蚀性能。其中,碳高、耐磨性好,但抗冲击能力下降。气焊的稀释率比电弧焊低,母材熔化量少、熔深较浅,堆焊质量高而被广泛应用。但气焊时由于被焊工件受热面积大、温升慢,工件变形量较电焊大。堆焊金属的化学成分及硬度一般是指堆焊二层以上的堆焊金属而言。

参数

标准:

相当AWS RCoCr-G

说明:

S190是高碳钴铬钨合金堆焊焊丝。该焊丝耐磨性非常好,但抗冲击性较差。在600℃以上具有良好的耐蚀、耐热、耐磨性能。常采用钨极气体保护焊和氧-乙炔碳化焰的堆焊工艺。

S190 is a high-carbon cobalt-chromium-tungsten alloy surfacing welding wire. The welding wire has very good wear resistance but poor impact resistance. It has good corrosion resistance, heat resistance and abrasion resistance above 600℃. Often use tungsten gas shielded welding and oxygen-acetylene carbonization flame surfacing process.

用途:

广泛应用于三维形钻孔工具的支承面。

It is widely used in the supporting surface of three-dimensional drilling tools.

焊丝化学成分:

C Mn Si Cr W Ni Fe Cu
3.0~4.0 ≤1.0 ≤2.0 24.0~30.0 12.0~16.0 ≤4.0 ≤3.0 余量

堆焊金属常温硬度:

HRC=52~60

以上化学成分及常温硬度指堆焊二层以上的堆焊金属。

The above chemical composition and normal temperature hardness refer to the surfacing metal of more than two layers.

注意事项:

1. 用氧-乙炔碳化焰进行堆焊,焰心与内焰的长度比应保持为1:3。

2. 焊接面的边角部分一定要加工成圆角。并在清除母材表面的氧化物及油等污物后进行堆焊。

3. 应当根据母材的种类和工件大小,选择适当的预热温度进行预热。

4. 堆焊时,母材只须加热到呈“出汗”(润湿)状态,便可加入焊丝熔滴,而母材不应熔化。每堆焊一层可用碳化焰在焊层表面进行重熔,检查有无气孔,凹陷或堆焊不足等缺陷,一经发现,即加以焊补。

5. 堆焊后的工件必须立即放入干燥及预热的沙缸或草灰中,使其缓冷,以避免裂缝。

6. 堆焊层须先经粗磨,如发现有缺陷时,应将工件重新预热,仍按上述步骤进行补焊。

1. Use oxygen-acetylene carbonization flame for surfacing welding, and the ratio of the length of the flame core to the inner flame should be kept at 1:3.

2. The corners of the welding surface must be processed into rounded corners. And after removing the oxide and oil on the surface of the base material, surfacing welding is carried out.

3. The appropriate preheating temperature should be selected for preheating according to the type of base material and the size of the workpiece.

4. During surfacing welding, the base metal only needs to be heated to a "sweat" (wet) state, and then welding wire droplets can be added, and the base metal should not be melted. Each layer of surfacing can be remelted with a carbonized flame on the surface of the welding layer. Check for pores, dents or insufficient surfacing. Once found, weld repairs.

5. After surfacing, the workpiece must be immediately put into a dry and preheated sand tank or straw ash, so that it can be slowly cooled to avoid cracks.

6. The surfacing layer must be rough ground first. If any defects are found, the workpiece should be preheated again, and the repair welding should still be carried out according to the above steps.
