Accurate inverter DC resistance welding principle:
1. After the weldment is assembled, the pressure is applied through the electric comparator, and the current is used to pass through Connector Resistance welding refers to the welding method of resistance heat generated on the contact surface and the adjacent area of. Resistance welding includes resistance spot welding, resistance projection welding, resistance seam welding and resistance butt welding. It is characterized by high production efficiency, low cost, material saving and easy automation. Therefore, it is widely used in various industrial departments such as aviation, aerospace, energy, electronics, automobile and light industry door , is one of the important welding processes.

Factors influencing resistance welding quality |
Influence of welding current | The influence of current on heat generation is greater than that of time and pressure. Therefore, in the welding process, it is a parameter that must be strictly controlled. The welding current is too small to form a core or the size of the core is small, and the strength of the welding point is small; If the welding current is too large, the welding workpiece will overheat, splash, and the indentation will be too deep. |
Influence of welding time | In order to ensure the size and strength of the solder joint, the welding time and welding current can complement each other within a certain range. In order to obtain a certain strength of solder joints, high current and short time (strong condition, also known as hard specification) can be used, or low current and long time (weak body condition, also known as soft specification) can be used |
Influence of electric pressure | The electric pressure has an obvious effect on the total resistance between the two electric comparators. The electric pressure is small, which is easy to generate splash. With the increase of the electric pressure, the total resistance decreases. When the electric pressure increases and the welding current remains unchanged, it cannot compensate for the decrease of heat production caused by the decrease of total resistance. Therefore, the strength of the welding spot decreases with the increase of the welding pressure. The solution is to increase the welding current while increasing the pressure. |
Influence of electric shape and material properties | Since the contact area of the electric comparator determines the current density, and the resistivity and thermal conductivity of the electric comparator material affect the generation and loss of heat, the shape and material of the electric comparator have a significant impact on the formation of nuggets. With the deformation and wear of the electric coupler end, the contact area increases and the strength of the solder joint decreases. |
LCD inverter DC resistance welding characteristics JYEE | Guangzhou Jingyuan Electronics |
1. DC output. The welding current is pulsating DC (and the waviness is small), without the disadvantage of AC zero crossing discontinuous heating of the workpiece. The heat is concentrated, which improves the welding thermal efficiency Metallic materials It is especially suitable for welding with some difficult welding materials. The welding process is stable and the welding quality is significantly improved. At the same time, the electrical life is extended.
2. It is controlled by MCU and has the function of current, voltage and power monitoring.
3. The inverter bridge adopts soft switching technology to reduce switching loss and electromagnetic interference.
4. It has fault diagnosis and emergency signal startup functions such as current abnormality, monitoring value overrun, network voltage overrun, overheating, etc.
5. When the inverter bridge current is abnormal, it automatically turns off to enhance system protection.
6. Three stage heating setting, with current slow rise and slow fall function, wide time range setting (0-250ms or 0-1s), suitable for complex welding process needs.
7.20 sets of parameters are stored to facilitate the use of various welding varieties.
8.240x128 LCD display, displaying multiple contents at the same time.
9. Strong external communication function: welding end, fault, counting signal, RS-232 data communication port (optional), convenient for automatic welding.
10. EEPROM is used for data storage, without battery life problem.
11. Fast response. Due to the high inverter frequency (4kHz, 1kHz), the inverter frequency of specific models of machines can be referred to Table 1. The power on time control cycle is 0.25ms or 1ms, which is 80 or 20 times higher than the 20ms of the common AC welding machine, and the control accuracy is significantly improved. Compared with the capacitor energy storage welding machine, it does not need charging and discharging, and its controllability is significantly enhanced. It is especially suitable for the welding of accurate parts and high-quality, high-precision and high-speed welding.
