What Are The Operational Requirements For Welding Cables With An Electric Welder? What Is The Role Of Welding Robots In Welding Cables?

-

In order to eliminate the unsafe factors of the electric welding machine and avoid the occurrence of electric shock accidents, the welder should follow the following points when using the electric welding machine to weld cables: The electric welding machine is required.

1. Welding tongs—Use qualified welding tongs. There should be a protective cover over the terminal stud. The welding tongs must have good insulation properties, and it is strictly forbidden to use self-made simple welding tongs.

2. Welding cable—When using multi-strand thin copper wire without a connector cable, the welding cable should be connected with terminal blocks to the welding machine terminals. To prevent loose contact, overheating and sparks caused by random winding. There should be a protective cover over the terminal stud. The length of the welding cable is generally not more than 20~30 m. If it is too long, the voltage drop of the wire will increase. When the welding cable passes through the channel, protective measures such as protective sleeves and pipes must be taken. It is strictly forbidden to use scaffolding, metal railings, rails, and other metal objects to overlap instead of wires to prevent fire and electric shock accidents caused by poor contact.

3. Welding is not allowed to be overloaded—the electric welding machine is not allowed to be overloaded during use, otherwise, it will burn out the electric welding machine or cause a fire due to overheating. At the same time, overloading will cause insulation damage, and may also cause leakage and electric shock accidents.

4. Before welding, check whether the welding equipment and tools are safe. For example, whether the grounding of the welding machine and the contact of each wiring point are good, whether the insulating sleeve of the welding cable is damaged, etc.

5. Before welding on the equipment, the ground or neutral wire of the equipment should be removed first, and then restored after welding.

6. Before welding, check the working environment, eliminate dangerous factors, and set up monitoring personnel. When the distance between other personnel and related facilities is too close, screen protection and safety separation should be adopted to ensure safe operation. Seat belts must be fastened when welding at heights.

7. Welders should wear insulating gloves when changing electrodes.

Problems with welding robots in welding cables

1. It may be that the welding position is incorrect or there is a problem with the welding torch. At this time, it is necessary to consider whether the TCP (position of the center point of the welding torch) is accurate and adjust it. If this happens frequently, check the zero position of each axis of the robot and re-calibrate to correct it.

2. If there is an undercut problem, the welding cable may be improperly selected, and the angle of the welding torch or the position of the welding torch may be wrong, which can be adjusted appropriately.

3. The problem of pores may be due to poor gas protection, the primer of the workpiece is too thick, or the protective gas is not dry enough, which can be dealt with by corresponding adjustments.

4. Excessive spatter problem It may be due to improper selection of welding parameters, gas composition, or excessive wire lengthening. The welding parameters can be changed by adjusting the power of the machine, the gas mixing ratio can be adjusted by adjusting the gas proportioning instrument, and the relative position of the welding torch and the workpiece can be adjusted.

5. After welding, the arc crater is formed after cooling. When programmable, the function of the submerged arc crater is added in the working step, which can be filled.

We combine our experience in cable operation over the years with the application of solid Bauer edge theory to analyze the causes of insulation breakdown of power cables.  The purpose is to cast a brick to attract jade, and electrical counterparts to find specific measures to prevent cable insulation breakdown , improve the level of safe operation of the cable and extend the service life of the cable. I. Breakdown of Solid Insulation 1. Solid insulation breakdown of the form of insulation material is also known as dielectric. When the voltage applied to the dielectric exceeds a certain critical value, the electric field strength in the dielectric exceeds the level it can withstand. Through the dielectric current increases sharply, the dielectric rupture or decomposition, the complete loss of insulation capacity. This phenomenon is called dielectric breakdown. Different dielectric, the form, and mechanisms of breakdown are different, field dielectric breakdown can generally be divid...

 For OPPC phase line fiber optic cable conductor, due to the existence of discharge, over the pulley, tightening the line caused by the structure elongation and operation of the temperature rise in the process of expansion elongation and creep elongation generated by plastic deformation, so the fiber residual length requirements are very strict. Fiber optic units should have good mechanical protection to ensure that the fiber is not extruded. To prevent moisture intrusion and affect the service life of the fiber, the fiber should be placed in a closed tube, or take other moisture-proof measures. Then OPPC phase line fiber optic cable wire in the transportation and installation process should pay attention to what issues? 1. The cable tray with fiber optic cable should be rolled in the direction indicated on the side of the plate. Rolling distance should not be too long, and generally should not exceed 20 meters, rolling should pay attention to prevent obstacles to damage the packa...

A cable withstand voltage test is a way to find faults in the presence of cables. It is easily affected by various factors during the test, resulting in problems such as failure and short circuits. The main methods of several cables to withstand voltage tests are described below. The First, Ultra-Low Frequency Withstand Voltage Test The ultra-low frequency (0.1Hz) withstand voltage test method first appeared in 1980. And it is mainly a non-destructive test method for observing whether there is an insulation defect in cable operation. And the method has been verified by a large number of laboratory tests and field tests.  The low-frequency withstand voltage test has a good application effect in the low-voltage power cable withstand voltage test. The method utilizes the principle of converting 50 Hz alternating current into direct current voltage through rectification and filtering.  And then converting the direct current voltage into an alternating current voltage of 1 kHz thro...
