山东数控焊接设备厂家这里为大家详细介绍一下自动焊接设备在使用过程中易产生的四个的问题，让您在之后的时间里更好的进行操作工作。

Shandong CNC welding equipment manufacturer here introduces four problems that are easy to occur in the use of automatic welding equipment, so that you can operate better in the future.

1.自动焊焊接时会产生焊缝夹渣

1. Slag inclusion will occur during automatic welding

主要有以下三个方面的原因造成的：

It is mainly caused by the following three reasons:

打底焊后不，致使在快速热焊时，未能使根部熔渣完全溢出。

After backing welding, the slag at the root can not be completely overflowed during rapid hot welding.

打底焊清根的方法不当，使根部焊道俩侧沟槽过深，呈现W状。在快速热焊时，流到深槽的熔渣来不及溢出而形成夹渣。

The method of backing welding and back gouging is improper, so that the grooves on both sides of the root pass are too deep, showing a W shape. During rapid hot welding, slag inclusion is formed when the slag flowing to the deep groove does not have time to overflow.

在仰焊位置收弧过快也易产生夹渣。

If the arc is stopped too fast in overhead welding position, slag inclusion is easy to occur.

2.焊缝产生裂纹的原因

2. Causes of cracks in welds

如果施工地段起伏较大，土墩未及时垫到位，使管子处在受力状态，在焊接收弧点,尤其是6点钟位置易出现应力裂纹。

If the construction section fluctuates greatly, and the soil pier is not padded in place in time, the pipe will be in a stressed state, and stress cracks will easily appear at the welding arc stopping point, especially at 6 o'clock.

在焊接过程中，如果早松开或撤离对口器，致使熔池中的铁水未来的及凝固好，在焊接收弧出容易产生裂纹。

In the welding process, if the butt joint is loosened or removed early, the molten iron in the weld pool will be well solidified in the future, and cracks will easily occur when the arc is stopped.

焊工在仰焊位置采用直接熄弧等不当的收弧方法，致使熔池未填满形成弧坑而出现弧坑裂纹。

The welder used improper arc extinguishing methods such as direct arc extinguishing at overhead welding position, which resulted in crater cracks due to incomplete molten pool.

3.焊接时内凹产生的原因

3. Causes of concave during welding

打底焊时熔透深度不够。

The penetration depth is not enough during backing welding.

焊接电流过大，热焊时在5-7点位置焊速太慢。

The welding current is too high, and the welding speed is too slow at points 5-7 during hot welding.

对口间隙过大。

The gap between abutments is too large.

4.焊接过程中产生气孔的原因：

4. Causes of air holes during welding:

盖面焊时，熔池过热，吸覆大量的周边空气。

During cover welding, the molten pool will overheat and absorb a lot of surrounding air.

盖面焊时，焊条摆动幅度太大，熔池保护不良。

During covering welding, the electrode swings too much and the molten pool is poorly protected.

根部间隙过小，容易产生根部针形气泡。

The root gap is too small, which is easy to produce needle shaped bubbles at the root.

焊条未在规定时间内用完或长时间暴露在空气中。

The welding rod is not used up within the specified time or is exposed to the air for a long time.
