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.

What are the characteristics and applications of hydraulic jacking system?

●Application

1.The hydraulic jacking system are mainly used for vertical tank top to bottom construction.

2.Also it can be used for mega work piece jacking or lifting.

●Features

1.The system consists of hydraulic pump station, cylinders, steel wire, and strokes. Easy to installation and operation;

2.The system utilizes PLC central control to handle lift. Each power pack is equipped with auxiliary balance device to guarantee the precision of simultaneously lifting.

3.Hydraulic jacking system pump station has subsidiary manual control and central control two operation models. The cylinder can be adjusted to lift separately or to lift with several others as one group, and multi groups can also be integrated to lift reach better precision and better welding effect.

4.All the cylinders are with safety valve. It can be automatically locked to avoid cylinder/ tank dropping even under situation of power off, high-pressure hose broken, burst.

5.The cylinder is with one high pressure hose to avoid oil leaking that usually happen by the traditional multiple hoses. Cylinder will return to initial condition by itself weight.

6.Stroke of Hydraulic cylinder is 1475mm, which can satisfy each annular shell with 2500 plate one-step lift. Greatly reduce the time waste.

Vertical seam welding machine can match around 20-30 people skilled welder and butt/fillet welding tractor can match 6-15 skilled welder.

What are the types of hydraulic jacking system?

At present, we have three types of hydraulic jacking system in WINCOO Engineering Co., LTD. They are the following three: Advanced hydraulic jacking system, Simple unfixing Holding -latch hydraulic Jacking system and Simple chain type hydraulic jacking system.

What is the working principle of hydraulic jacking system?

Hydraulic jacking system (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking hydraulic jacking system and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jacking system, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.

What are the construction steps of hydraulic jacking system?

The following short description gives the working procedure in outline. It can in certain details be modified when required.

1.The tank bottom – plates are placed on the prepared foundation and welded together.

2.The beams or lattice work of the roof are assembled and finally joined to the upper rim of the shell ring.

3.The hydraulic jacking system is installed in the tank. The plates of the second shell ring (next to the top ring) are positioned outside the first one.

4.The completed part of the tank (roof and top shell ring) is lifted hydraulically to a height at which the plates of the second ring can be moved into place and the roof sheeting can be completed.

5.The plates of the second shell ring are located exactly and welded together to the lower edge of the first ring.

6.The plates of the third shell ring are placed outside the second shell ring.

7.The completed part of the tank (roof the two uppermost shell rings) is lifted.

8.The above cycle of operations is repeated until the last (bottom) shell ring is finished.

9.The entire tank is lowered down to the bottom plate and welded to this.

10.The lifting equipment is dismantled.

Hydraulic jacking system is mainly used in large tank construction. WINCOO ENGINEERING CO.,LTD is supplying tank hydraulic jacking system to tank contractors worldwide.

Hydraulic jacking equipment is a new and special lifting equipment powered by hydraulic oil. By pushing the reciprocating movement of the hydraulic cylinder piston, load conversion is carried out between the upper clamping mechanism connected with the upper end of the piston and the lower clamping mechanism connected with the lower part of the cylinder, so as to realize lifting.The hydraulic jacking equipment is a single-acting two-stage hydraulic cylinder, used for vertical take-off and landing work, return need external force or self-weight back.The equipment is compact, stable, easy to operate, adjustable load, fast installation, high synchronization accuracy.Today we are going to focus on the simple hydraulic jacking system.
