How to avoid welding problems
2020-05-06 316
As we all know, there are many enterprises applying welding robots in the welding industry. That's because robots not only have high production efficiency, but also have many advantages. This is also an important reason why enterprises use welding robots to replace traditional handwork. First of all, we should know that this yellow thing is actually the impurity in the welding wire and welding base metal. The main reason is that the high-temperature oxidation of silicon manganese element reacts

Causes of cold crack in steel welding
2020-04-08 310
In the use of welding tools to carry out welding operations, in the process of steel welding, there are still steel cold cracking phenomenon. There are many reasons for this situation, which are generally related to the chemical composition, steel degree, preheating temperature and cooling conditions of steel. In order to maximize the occurrence of cold cracking phenomenon of underground steel, we must pay attention to the following points in technology: first of all, when welding steel, we shou

Two different modes of laser welding
2020-03-18 403
When using a laser welding machine for laser welding, there are two different ways or the energy can be transferred from the laser to the welding data. Depending on the power density, which is the power factor of the laser and the weld area, the laser welding method can be in the form of conduction or keyhole. You may be familiar with it now because it is a form of keyhole that is often used in craft welding. It should be emphasized that the type of welding that is occurring is determined by th

The thickness of workpiece should be set when using welding equipment
2020-02-21 320
Before using manual flume welding equipment, it is necessary to check the voltage and current. In order to ensure that it is within the rated power range of the machine, it should not be too high or too low. However, only under normal conditions, welding will definitely affect. As long as ability is used, it can guarantee the function. Also pay attention to the parameter setting of welding machine, which needs to be set according to different workpiece and different thickness. In particular, th
