In resistance welding equipment, seam welding is widely used in the manufacturing of joints with specified sealing properties, and sometimes it is also used to weld general non sealing sheet metal parts. The thickness of the welded metal material is usually between 0.1 and 2.5mm.
A seam welding machine refers to a resistance welding machine that assembles welded components into overlapping or butt joints and places them between two roller electrodes. The roller electrodes pressurize the welded components and rotate them, continuously or intermittently pulse to form a continuous weld seam. It can be said that seam welding machines are an evolution in spot welding.
Application of seam welding in resistance welding equipment
The main controller of the seam welding machine adopts a motion controller programmable controller as the basic control module. According to user requirements, the entire equipment has strong intelligence and flexibility, and should be a cost-effective and reliable controller.
The electrode material, electrode shape, and overall dimensions of resistance welding equipment ensure good cooling of the electrode, and the cone shaped electrode head end face is considered very good. The requirement for the end face diameter is 6-8mm. If it exceeds 8mm, timely grinding should be carried out, and during welding, the upper and lower electrodes of the welding clamp should be kept perpendicular to the plate as much as possible.
When the external size of the electrode is expanded, due to the expansion of the contact area, the current density decreases, and the heat dissipation effect improves, the heating degree of the welding area is weakened, resulting in a decrease in the external size of the molten core and a decrease in the load-bearing capacity of the welding point.
Selection of electrode materials for resistance welding equipment
The medium frequency inverter point projection welding machine is one of the most advanced welding equipment in Muzhang, with a wide range of applications. The welding transformer has a small volume and a large output energy. Due to the increase in the frequency of its welding transformer from 50/60HZ of the current market power to 1000HZ, it can greatly reduce the weight of the iron core material. Adding the rectifier diode in the secondary circuit of the transformer converts electrical energy into direct current for welding machine applications, which can greatly improve the induction coefficient value of the secondary circuit and save more than 30% of user power consumption.
Juntengfa is committed to the intelligence and automation of resistance welding equipment, with over 20 years of industry experience. There are numerous cases in the production and manufacturing industries such as military industry, aviation, automobiles, home appliances, and 3C electronics. Master the technology of medium frequency spot welding machines, seam welding machines, nut spot welding machines, and flash butt welding machines, select high-quality copper materials and components with good conductivity to form the equipment.
