Spot welding machine is a mechanical equipment that adopts the principle of double-sided double point overcurrent welding. During operation, two electrodes apply pressure to the workpiece, causing two layers of metal to form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, an instant thermal fusion is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a circuit, without damaging the internal structure of the welded workpiece-- Chuangde Laser
The spot welding machine has a simple structure, and the welding time, pressure, and current can be adjusted. It can be used for spot welding of different metal thickness plates, and there will be no smoke, noise, or pollutants during the welding process, which makes customers highly evaluate precision spot welding machines.
Spot welding can be widely used for different types of metal materials. Specifically, low-carbon steel or soft steel is often spot welded because it has lower thermal conductivity and higher resistance compared to other metals. If the electrodes are frequently replaced and the surface and welding head are kept free of contaminants, then zinc coated steel can also be spot welded. Stainless steel, nickel alloy, and titanium can also be spot welded.
Resistance spot welding is a multifunctional and widely used process. Spot welding machines are widely used in industries involving metal products such as new energy vehicles, electronic and electrical component processing, aerospace, mechanical and hardware manufacturing, and home appliance manufacturing.
In the new energy vehicle industry, compared to the traditional automotive industry, spot welding machines have more applications because new energy vehicles use battery packs to provide power, and electric motors convert electrical energy into driving energy. Spot welding machines are not only used in vehicle body coverings and structural components, but also in battery packs.
The current new energy battery pack is mostly composed of multiple battery groups connected by copper and aluminum bars. Spot welding machines are mainly used for high-temperature diffusion welding of copper and aluminum bars. In the production of electric vehicle batteries, spot welding is used to connect individual batteries together to form a complete battery pack. With the advancement of quantitative production, the application of aluminum in new energy vehicles is becoming increasingly widespread-- Chuangde Laser
In the electronic and electrical industry, spot welding machines have replaced manual welding, greatly improving welding efficiency and significantly reducing leakage rates. While meeting the precision requirements of the equipment, it also greatly improves the welding quality for customers and reduces production costs.
The Chinese spot welding machine industry has developed rapidly and expanded rapidly through extensive international exchanges and the introduction and absorption of advanced foreign technologies. Empowering various industries, reducing production costs, and improving production efficiency.
