  Friends who have just come into contact with welding equipment may mix spot welding machines and electric welding machines into one type of equipment. This is actually a wrong concept. Today, based on this question, I will explain the difference between spot welding and electric welding and their respective characteristics in detail. What are there, I hope to help you increase your mechanical knowledge.

  Spot welding machine :

  Resistance spot welding is abbreviated as spot welding, which is a resistance welding method in which the weldment is assembled into a lap joint and pressed between two electrodes, and the base metal is melted by resistance heat to form a welding spot.

  When working, the two electrodes press the workpiece to make the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and when the welding current flows from one electrode to the other electrode, the two contact resistance points form an instant thermal fusion. Spot welding machine The heating time is short and the heat is concentrated, so the heat-affected zone is small, and the deformation and stress are also small. Normally, it is not necessary to arrange the correction and heat treatment process after welding.

  The welding process does not require filler metals such as welding rods and wires, as well as welding materials such as oxygen, acetylene, and argon. The welding cost is low, it is more environmentally friendly, simple to operate, easy to achieve mechanization and automation, and improves labor costs. With high productivity, no noise and harmful gases, it is suitable for mass production.

  Electric welding machine:

  Electric welding machine uses electric energy to instantly convert electric energy into heat. Electric welding machine is suitable for working in a dry environment and does not require too many requirements. Because of its small size, simple operation, convenient use, and fast speed, it is well received by the market. Favor, especially for parts that require high strength. It can connect the same metal material or dissimilar metal materials instantly, but the welding method is different. After heat treatment, the weld seam has the same strength as the base metal and has better sealing performance. , Which solves the problems of sealing and strength for the manufacture of storage gas and liquid containers.

The influence of the pressure of the intermediate frequency spot welder on the welding quality
In the actual intermediate frequency spot welding machine, adjusting the electrode pressure is one of the key parameters of spot welding. The nature of the workpiece adjusts the parameters and pressure. Excessive or too small electrode pressure will reduce the load-bearing capacity and dispersion of the solder joints, especially for tensile loads.

Introduction to the workflow of automatic battery spot welding machine
One is to adjust the effective value of the welding current to make the heat of the internal power source change significantly; second, due to the concentration and contraction of the contact points of the two weldments during the operation of the automatic spot welding machine, concentrated heating occurs there , And the plastic junction area first seems to form unevenly during spot welding plus this unfavorable factor
