Fish scale welding – the highest level of welding technology

Fish scale welding, which many people may not have heard of, is a welding process that is named after the fish scales that appear when welding a flat surface.

It is a visual impact on human beings, with its full surface and colourful and dynamic, it is a feast for the eyes, but the difficulty of welding fish scales is very high, so this welding technology is also recognized as the most advanced welding technology in the world.

When operating, the hand controlling the welding gun must be steady to avoid shaking hands and burning the dock pole causing tungsten trapping in the molten pool; the wire transport also requires good technique and is chosen according to the size of the break, with the wire being placed in the middle of the pool for continuous feeding when the break is small.


This usually requires a good deal of skill to avoid touching the docking electrode so that the torch can move from side to side in order to make the edges fuse well.

Current is also critical, as a low current will tend to fail to fire and cause the rod to stick to the weld.
If the current is too high, it will easily burn through and cause deformation of the weld.

Therefore, it is not easy to produce a good-looking fish scale weld. In addition to mastering the relevant skills, you must also practice your welding skills diligently so that you can produce a wonderful fish scale weld.

The most advanced welding method for gear laser welding technology

Laser welding technology is currently the most advanced welding method in the field of processing. In contrast to conventional welding technology, laser welding technology is non-contact welding. No pressure is required for the operation process. With high welding speed, high efficiency, large depth, small residual stress and deformation, laser welding technology can weld refractory materials such as high melting point metals, and can even be used to weld non-metallic materials such as ceramics, organic glass, etc. The welding of shaped materials is effective and flexible.

For difficult to weld parts, non-contact welding with flexible transmission can be used. The laser beam can separate light in time and energy and can handle multiple beams at the same time, which provides for more precise welding.

Due to its high power density and rapid release of energy, laser welding is more efficient than conventional methods when it comes to process efficiency. Laser welding processes have superior processing characteristics to conventional processes. Laser welding uses high-energy laser pulses to locally heat the material in a small area.

Conventional laser welding equipment

Conventional laser welding equipment Resistance welding or argon arc welding is usually used. The disadvantage of resistance welding is that it can easily lead to deformation of the workpiece, and resistance welding requires welding through both sides of the joint.

Argon arc welding, on the other hand, uses non-consuming electrodes and shielding gas and is usually used to weld thin workpieces. However, its disadvantages are that the welding speed is slow and the heat input is much greater than that of laser welding equipment, which also tends to lead to distortion.

This is also the reason why traditional welding machine equipment requires high technical requirements for the operator, and after using traditional welding, the workpiece has to be polished, which not only seriously affects the work efficiency, but also polishes the workers in a long-term flying chip dust environment, which is also easy to cause harm to the human body.

How to solve the weak light from industrial laser welding machine?

In recent years, laser welding machine equipment has occupied a place in industrial welding due to its stable performance, reliable use, fast welding speed, wide welding range, long life of consumables and other characteristics.

When we encounter laser welding equipment out of the light is very strong at the beginning, and then gradually become weak (light weak), and eventually lead to the inability to melt the wire or sparks at the copper mouth, then how do we solve it?

Analysis of the reasons for the appearance of weak light.

Usually this situation, generally are welding gun lens damage, including not limited to protective mirror, focus, collimation, reflection, etc., any one or more of these damage may cause the weak light situation.

1, first replace the protective mirror and look at the focus, and then to check the reflection and collimation, replace the damaged lens can be.

2, if the above checks are completed, you can then check the laser fiber head position for dirt or damage.

Damage to the lens analysis.

  1. classification of damage: abnormal motor oscillation due to interference, or unadjusted red light that is too biased, and in general the seals will burn together.
  2. damage to the convex surface of the lens: generally common to pollution, such as replacement without protection, in the form of dotted black spots.
  3. damage to the plane of the lens: due to diffuse reflection of the laser, mostly caused by reflection, which creates a focus on the lens and burns the coating, in the form of white spots. Convex surfaces also have this morphology and are formed on the same principle.

Lens fault treatment: replacement of the damaged lens.

Follow-up on how to avoid.

In hand-held laser welding, the lenses are usually replaced with the highest frequency, and generally for the causes of damage, we can carry out relevant preventive measures.

  1. the use of original lenses.
  2. pay attention to anti-pollution when replacing them.
  3. techniques try not to weld vertically, especially when welding highly reflective materials.
