Three common problems in laser cutting in carbon steel

When laser cutting carbon steel, there will be a common phenomenon that burrs appear on the work piece.

Why would such phenomenon happen, XT laser will take you to learn it.

عندما يقطع الليزر الفولاذ الكربوني ، فإن قطعة العمل بها نتوءات. 

فيما يلي الأسباب المحتملة:

At first,the laser focus position is offset.

It’s necessary to make the focus position test.

And adjust offset according to the offset of the laser focus;

Secondly,the output power of the laser is not enough.

It is necessary to check whether the work of the laser generator is normal.

If it is normal, observe whether the output value of the laser control button is correct.

Thirdly, The cutting line speed is too slow.

And it is necessary to increase the line speed during operation control;

Fourthly, The cutting gas is not pure enough.

It is necessary to provide high quality cutting working gas;

Fifthly, The instability of the machine when it’s running time is too long.

At this time, we need shut it down and restart.

الليزر غير مقطوع بالكامل. 

فيما يلي سبب عدم قطع الليزر تمامًا:

(1) The selection of the laser nozzle does not match the thickness of the processing plate.

It’s necessary to replace the nozzle or processing plate;

(2) The القطع بالليزر line speed is too fast. And we should control and reduce the line speed.

يجب أن نأخذ في الاعتبار الأسباب التالية عند وجود شرارات غير طبيعية على قطع الفولاذ الكربوني.

As we all know that the spark is long, flat, and has fewer splits when cutting carbon steel normally.

And the occurrence of abnormal sparks will affect the smoothness and quality of the cut section of the workpiece.

In this case, if other parameters are normal, we should consider the following:

(1) The laser head nozzle has serious loss.

We should replace the nozzle in time;

(2) In the case of no new nozzle replacement, we should increase the working gas pressure .

(3) إذا كان الخيط الموجود في الوصلة بين الفوهة ورأس الليزر مفكوكًا ، فيجب تعليق القطع على الفور ، والتحقق من حالة توصيل رأس الليزر ، وإعادة الخيط.
