山東數(shù)控焊接設備廠家這里為大家詳細介紹一下自動焊接設備在使用過程中易產生的四個的問題，讓您在之后的時間里更好的進行操作工作。

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.自動焊焊接時會產生焊縫夾渣

1. Slag inclusion will occur during automatic welding

主要有以下三個方面的原因造成的：

It is mainly caused by the following three reasons:

打底焊后不，致使在快速熱焊時，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當，使根部焊道倆側溝槽過深，呈現(xiàn)W狀。在快速熱焊時，流到深槽的熔渣來不及溢出而形成夾渣。

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.

在仰焊位置收弧過快也易產生夾渣。

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

2.焊縫產生裂紋的原因

2. Causes of cracks in welds

如果施工地段起伏較大，土墩未及時墊到位，使管子處在受力狀態(tài)，在焊接收弧點,尤其是6點鐘位置易出現(xiàn)應力裂紋。

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.

在焊接過程中，如果早松開或撤離對口器，致使熔池中的鐵水未來的及凝固好，在焊接收弧出容易產生裂紋。

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當?shù)氖栈》椒?，致使熔池未填滿形成弧坑而出現(xiàn)弧坑裂紋。

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.焊接時內凹產生的原因

3. Causes of concave during welding

打底焊時熔透深度不夠。

The penetration depth is not enough during backing welding.

焊接電流過大，熱焊時在5-7點位置焊速太慢。

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

對口間隙過大。

The gap between abutments is too large.

4.焊接過程中產生氣孔的原因：

4. Causes of air holes during welding:

蓋面焊時，熔池過熱，吸覆大量的周邊空氣。

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

蓋面焊時，焊條擺動幅度太大，熔池保護不良。

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

根部間隙過小，容易產生根部針形氣泡。

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

焊條未在規(guī)定時間內用完或長時間暴露在空氣中。

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