How do you know about tank welding machines?

Large vertical steel storage tank is an important crude oil and refined oil storage and transportation equipment in the petrochemical industry. Welding is the main process of storage tank construction, which is of decisive significance to the construction quality and progress. Therefore, the demand for tank welding machines in the processing industry continues to rise.

How to deal with solder balls at the arc end of tank welding machine?

1. Welding offset

It may be that the welding position is not correct or there is a problem with the welding torch. At this time, it is necessary to consider whether the TCP (the 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. Undercut

The welding parameters may be improperly selected, the angle of the welding torch or the position of the welding torch may be incorrect, and the power can be adjusted appropriately to change the welding parameters, adjust the posture of the welding torch and the relative position of the welding torch and the workpiece.

3. Stomata

It may be that the gas protection is poor, the primer of the workpiece is too thick or the protective gas is not dry enough, and it can be dealt with by adjusting accordingly.

4. Too much splash

It may be due to improper selection of welding parameters, gas composition or too long wire extension. We can adjust the power to change the welding parameters, adjust the gas proportioning instrument to adjust the gas mixture ratio, and adjust the relative position of the welding torch and the workpiece.

5. An arc crater is formed after cooling at the end of the weld

Add the submerged arc crater function in the work step during programming, which can be filled.

What are the precautions for the use of tank welding machine?

When using the tank welding machine to weld the root of the weld, start welding at the lower edge of the spot-fixed weld. Welding arc ignition by scratching method. Don't rush to weld. After the arc is ignited, preheat the starting point of the weld. The preheating has two purposes: one is to avoid the low temperature of the spot-fixed weld at the starting point and the small current used for the welding current, and the sticking phenomenon occurs, resulting in pores and leaving defects in the quality of the weld. If it is welded directly, when it is welded to the upper end joint of the spot-welding seam, the temperature of the welding seam is low, and the temperature of the welding pool cannot reach the temperature state of normal welding, which will lead to the phenomenon of impermeability or poor fusion of the welded joint, which will affect the Weld quality.

What are the working steps of tank welding machine?

The strip material is introduced into the tank welding machine through the feeding machine, and the strip material is extruded and formed through the roller, and then arc welded with mixed gas shielded welding, rounded, output the pipe of the required length, cut by the cutter mechanism, and then straightened Straighten the machine. Spot welding machines are used for spot welding connections between tape heads. Tank welding machine is a comprehensive set of equipment that continuously welds strips into tubes, rounds and straightens them.
