Advantages of Ultrasonic Soldering Iron for Welding – Sonic4Lab

Good bonding strength: ultrasonic vibration makes the molecular layer of the welding material permeate and fuse with each other to form a solid welding joint. Compared with some traditional welding methods, its welding strength is higher, can withstand greater tension, pressure and other external forces, to ensure that the solar collector in the long-term use of the welding part is not easy to disconnect. For example, in the welding of the copper tube and aluminum plate of the collector, the robustness of the ultrasonic soldering iron welding can ensure the structural stability of the collector.

Precise welding control: You can precisely control the energy, time and position of the welding, making the welding process more accurate. For the solar collector, which requires high welding accuracy, the accuracy of the welding position can be ensured, and the welding deviation can avoid affecting the performance of the collector. And the heat affected area in the welding process is small, will not cause too much heat damage to the surrounding material, and maintain the original properties of the material.

Uniform and beautiful welding points: the welding points after welding are uniform and smooth, and the appearance quality is good, which meets the higher requirements for the appearance of solar collectors. At the same time, the uniform solder joint is also conducive to the uniform transfer of heat and improve the heat conversion efficiency of the collector.

High welding efficiency:

Fast welding: Ultrasonic vibration can make the welding material reach the welding temperature in a short time to complete the welding process. Compared with the traditional welding method, the welding speed is faster, which can greatly improve the production efficiency of the solar collector. For example, traditional welding of a solder joint may take a few seconds or even longer, while ultrasonic soldering iron welding may only take a few tenths of a second.

High degree of automation: it can be used with automation equipment to realize the automation of the welding process, and further improve the production efficiency and stability of welding quality. In the process of large-scale production of solar collectors, automatic ultrasonic soldering iron welding can reduce the error and labor intensity of manual operation.

Strong applicability:

Suitable for a variety of materials: It can weld a variety of metal materials, such as copper, aluminum, stainless steel, etc., which is very suitable for the welding of different material parts in the solar collector. For example, the welding between the copper tube and the aluminum plate of the collector can be well completed by the ultrasonic soldering iron.

Complex structures can be welded: For some complex parts of the solar collector, such as curved pipes, narrow Spaces, etc., the small welding head and flexible operation mode of the ultrasonic soldering iron can easily achieve welding, overcoming the limitations of traditional welding tools in complex structural welding.

Environmental protection and energy saving:

No flux: chemical substances such as flux are not needed in the welding process to avoid corrosion of the collector material and environmental pollution caused by flux residue. At the same time, it also reduces the cost of flux procurement and handling.

Low energy consumption: Compared with some welding methods that require high temperature heating, the energy consumption of ultrasonic soldering iron is low. It mainly relies on the energy generated by ultrasonic vibration to complete the welding, which has obvious advantages in energy consumption and meets the requirements of energy conservation and environmental protection.

Easy to operate:

The equipment is easy to operate: the operator can master the operation method of the ultrasonic soldering iron after simple training, and does not need to have a high level of welding technology. For solar collector production enterprises, it can reduce the skill requirements for operators and reduce the cost of human training.

Low maintenance cost: The equipment structure is relatively simple, easy to maintain, and the daily maintenance cost is low. As long as the equipment is cleaned, inspected and maintained regularly, the normal operation of the equipment can be guaranteed and the service life of the equipment can be extended.

The ultrasonic soldering iron consists of a high performance sheath heater and transducer, supplying heat and ultrasonic oscillations to the tip. The ultrasonic soldering is implemented by the cavitation effect which breaks the oxide surface and eliminates bubbles in solder. Using the solder alloy, can easily solder directly to glass, ceramics and other low solderability materials. It has been widely used in soldering solar cell, LED, ITO glass etc materials.
