Quality Control of Resistance Welding Products

News & Technicals Quality Control of Electric Resistance Welding Products Although resistance spot welding is the most suitable welding method for mass production, improper quality management can cause huge losses. At present, since online non-destructive welding quality inspection cannot be realized, it is necessary to strengthen the management of quality assurance. 1. Pressure InspectionThe heat of welding is greatly affected by the contact resistance between the electrode and the workpiece. During the resistance welding process, the pressure must remain constant, so it is necessary to frequently use a pressure tester to weld 2. Electrode PolishThe increase in the number of welding will increase the wear of the electrode surface. The rough surface of the electrode will cause splashes and rough marks on the surface of the workpiece, which will affect the appearance of the workpiece. Therefore, it is necessary to prepare more ground electrodes and replace the electrodes appropriately according…

How to Weld Copper Wire and Copper Sheet

News & Technicals How to Weld Copper Wire and Copper Sheet In the manufacture of electronic components, the connection of the copper wire and the brass sheet is generally done by soldering, which is troublesome and the welding effect is not good. At present, many of our customers choose spot welders to complete welding. Of course, there are also many methods and things to pay attention to. Let’s share with you today. 1. Both the copper wire and the brass sheet have very good electrical and thermal conductivity properties, so be sure to choose a resistance welding equipment with stable and concentrated welding current. We recommend using an intermediate frequency inverter DC spot welding machine. 2. The welding parameters of red copper wire welding and brass spot welding are similar, and both follow the welding method of high current and short time. If the current is small, the purpose of…

Basic Knowledge of Resistance Welding

News & Technicals Basic Knowledge of Resistance Welding When using metal materials to make parts, it is often necessary to cut the material to a specified size and then connect them. The methods of connecting materials include mechanical connection using rivets, metallurgical connection using welding, and physical connection using ultrasonic waves. Resistance spot welding is a method that uses metallurgy to connect metal materials efficiently and economically. Therefore, it is widely used in the industry. We call resistance welding of precision small workpieces precision resistance spot welding. Amada welding technology has continuously developed a variety of ultra-small, high-density installation of new precision resistance spot welding machines, replacing the previous metal connection processes such as soldering and riveting. The precision resistance spot welding machine is most suitable for the assembly of small, high-performance electronic parts and small parts in the precision machinery industry. Principles of resistance welding Welding…

Operation Skills of Resistance Spot Welding Machine

News & Technicals Operation Skills of Resistance Spot Welding Machine The resistance spot welding machine is a device that moves along a specified track at a selected welding speed, or the flux sends the welding head and welding gun to and keeps it in the position to be welded. The resistance spot welding machine is generally composed of a column, a beam, a slewing mechanism, and a trolley. Each component is a building block structure. Generally, columns and beams are the basic components, and the remaining components can be selected according to different user requirements. The columns and beams adopt bending and welding structural parts, which have very good rigidity. Light, medium, and heavy resistance spot welding machines all use triangular guide rails, and super heavy use flat square guide rails, all of which are ground and high-frequency hardened. Fully ensure the high precision and wear resistance of the guide…

Introduction of Spot Welding Process of Aluminum Plate

News & Technicals Introduction of Spot Welding Process of Aluminum Plate Classification and application of aluminum plates that can be resistance welded According to the different metal element content of the material, aluminum plates in my country are classified into 1-9 series. Aluminum alloy parts that can be used in automobile manufacturing, such as automobile engine parts, steering parts, and surface coverings of high-end automobiles, and hardware appliances such as equipment and instrument housings, and supporting structures for electronic devices, such as TV section back panels, etc. ； Because aluminum has high electrical conductivity and thermal conductivity, it is difficult to use resistance spot welding. Generally, the thickness of resistance spot welding used in civil and industrial products is generally less than 3+3mm, but there will be thicker aluminum in military or special industries. The material uses resistance welding spot welding technology. Classification and characteristics of aluminum plate spot welding…
