自動焊接設備的焊點焊道一般是白亮的，不過如果使用方法不正確的話，也可能導致焊出來發黑，如果自動焊接設備焊出來是黑的，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、氬氣沒有打開或者氣罐內已經沒有氬氣，需要檢查氬氣瓶閥門和氬氣表開關。

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、鎢針露出陶瓷嘴距離太長，在焊接過程中氬氣并沒有起到防氧化作用。

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、自動焊接設備的參數調節過大，沒有按照工況調節相應的材料及厚度所應設置的電流大小及放弧時間。

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、工件表面雜質過多，沒有提前清理工件表面的油污、氧化物等雜質。

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、工件工藝要求過高，該型號的自動焊接設備配置不足，無法完成焊接需求。

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

怎么操作不發黑？

How to operate without blackening?

1、選擇符合工件加工需求的山東自動焊接設備配置，并根據弓箭情況調節好相應的參數。

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、在焊接的時候，要選擇合適的焊絲，所填焊絲直徑好小于工件厚度。

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、焊接時，應盡量減小工件之間的焊縫距離，焊縫盡量清理干凈。

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，千萬別立刻移開焊槍，防止后焊點氧化。

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.
