DN-40 spot welding steel product specification Introduction DN series spot welder is widely used in metal cabinet manufacturing, construction machinery repair, auto parts, bicycle parts, profiled standard parts, handicrafts, electronic components, instruments, electrical switches , cable manufacturing, filter, muffler, metal packaging, chemical containers, wire mesh, mesh baskets and other metal products industries. DN series spot welder can low carbon steel sheet metal of different thickness, steel garden with garden steel, small diameter wire, steel and non-ferrous metal workpiece and various shaped pieces of high-quality, high efficiency welding. DN series spot welder can be equipped with highly reliable projection welding computer controller according to customers. It can accurately control the welding process in the "pressing", "welding", "maintain", "rest" Four program time, welding time in 0.02S - any adjustment between 4S, this controller is stable, affected by man-made factors, so as to ensure the stability of the quality of each solder joint, so that each solder joint quality piece exactly the same batch. This machine is the most important feature: low price, low failure rate, high joint quality and high efficiency. DN-40 spot welding steel use 1, welding should first adjust the position of the electrode rods, just press when the electrodes to the weldment, electrode arm parallel to each other. 2, the current adjustment switch series selected choice may weldment thickness and material. The power indicator should light after power, electrode force size adjustable spring pressure nut, change the compression obtained. 3. After the above adjustments can be connected to the cooling water before preparing welding power. Program welding process: weldment placed between two electrodes, depress the foot pedal, and the upper electrode in contact with the welding and pressing, while continuing depressed pedals, power contact switch is turned on, then start working transformer secondary weldment heating circuits are turned on. When after some time release the foot plate welding electrodes rise through the spring tension to cut off the power and then restore a single point welding process ends. 4, weldment preparation and assembly: steel weldment before welding shall remove all dirt, grease, scale and rust on hot-rolled steel, it is best to weld the first pickling, blasting or grinding wheel remove oxide. Unrefined weldments been able to spot welding, but seriously reduce the life of the electrode, while reducing production efficiency and quality spot welding. For a thin coating of low carbon steel welding directly.

In mass production should be standardized using a strong welding method, it will increase productivity, reduce energy consumption and reduce the deformation of the workpiece. 2, Welding current: Welding current depends on the circumstances of the weldment size, thickness, and the contact surface. Usually metallic conductivity, the greater the electrode force, welding time should be shorter. In this case the current density required increases. 3, electrode force: purpose electrode welding pieces of pressure to reduce the contact resistance of solder joints and ensure joint formation pressure required. 4, electrode shape and size: an electrode made of chromium zirconium copper made. Diameter of the electrode contact surface is roughly: δ≤ 1.5mm, the electrode contact surface diameter, 2δ + 3 (mm) δ≥ 2mm, the electrode contact surface diameter, 1.5δ + 5 (mm) δ- two weldments in a thin the thickness of the member of the (mm) diameter electrodes should not be too small, so as not to cause excessive heat and rapid wear. 5, the solder joint arrangement: the smaller the distance between joints, current shunting increases, and reduce the pressure spot welding place, thus weakening the strength of the solder joint. For low-carbon steel or stainless steel: pad center distance A ≌ 16.1δ (mm) DN-40 spot welding steel welding installation and maintenance welder must be properly grounded before use, in order to protect the personal safety. Former welder using a 500V megger test must be used between the high pressure side of the chassis welding insulation resistance of not less than 2.5 megohms before electricity. First cut off the power supply when maintenance before checking out of the box. After the first pass water welder welding, anhydrous prohibited work. Cooling water should ensure the supply of industrial water 5--30 ℃ under 0.15--0.2MPa water pressure. After the welding work is completed winter application of compressed air to blow water pipe in order to avoid the cracking water pipes.
