自动焊接设备的焊点焊道一般是白亮的，不过如果使用方法不正确的话，也可能导致焊出来发黑，如果自动焊接设备焊出来是黑的，可能原因有：

The weld bead of the automatic welding equipment is generally white and bright. However, if the use method is incorrect, it may also lead to black after welding. If the automatic welding equipment is black after welding, the possible reasons are:

1、氩气没有打开或者气罐内已经没有氩气，需要检查氩气瓶阀门和氩气表开关。

1. If the argon is not opened or there is no argon in the gas tank, check the valve of the argon cylinder and the switch of the argon meter.

2、钨针露出陶瓷嘴距离太长，在焊接过程中氩气并没有起到防氧化作用。

2. The distance between the tungsten needle and the ceramic nozzle is too long, so argon does not play an anti oxidation role in the welding process.

3、自动焊接设备的参数调节过大，没有按照工况调节相应的材料及厚度所应设置的电流大小及放弧时间。

3. The parameter adjustment of automatic welding equipment is too large, and the current size and arcing time that should be set for the corresponding material and thickness are not adjusted according to the working conditions.

4、工件表面杂质过多，没有提前清理工件表面的油污、氧化物等杂质。

4. There are too many impurities on the surface of the workpiece, and the impurities such as oil and oxide on the surface of the workpiece are not cleaned in advance.

5、工件工艺要求过高，该型号的自动焊接设备配置不足，无法完成焊接需求。

5. Workpiece process requirements are too high, and the automatic welding equipment of this model is insufficient to meet the welding requirements.

怎么操作不发黑？

How to operate without blackening?

1、选择符合工件加工需求的山东自动焊接设备配置，并根据弓箭情况调节好相应的参数。

1. Select the automatic welding equipment configuration that meets the workpiece processing requirements, and adjust the corresponding parameters according to the bow and arrow conditions.

2、在焊接的时候，要选择合适的焊丝，所填焊丝直径好小于工件厚度。

2. When welding, select the appropriate welding wire, and the diameter of the filled welding wire is better than the thickness of the workpiece.

3、焊接时，应尽量减小工件之间的焊缝距离，焊缝尽量清理干净。

3. During welding, the weld distance between workpieces shall be minimized and the weld shall be cleaned as much as possible.

4、焊接到末端后停留一秒左右，千万别立刻移开焊枪，防止后焊点氧化。

4. Stay for about one second after welding to the end. Never remove the welding gun immediately to prevent oxidation of the rear welding spot.
