Hwashi experts decipher pressure mode of spot welder for you


Resistance welding is composed of power supply, electrode, pressure mechanism and control system.The electrodes are made of a high-strength copper alloy whose interior is cooled with water.The pressure mechanism is basically pneumatic or hydraulic mechanism.Determine the control system according to the required weld quality.Use AC welding machine, inverter DC welding machine, intermediate frequency welding machine, energy storage welding machine, butt welding machine, flash welding machine and other equipment.Resistance welding machine is mainly used for all kinds of metal materials.


The method of welding by applying pressure to the electrode and welding using the resistance heat generated by the current flowing through the contact point is also known as contact welding. There are four types of resistive welding: spot welding, projection welding, seam welding and butt welding. Resistance welding is highly productive and easy to mechanize and automate, but the required welding machines are complex and power-intensive, mainly for mass production.


At present, the pressure mode of resistance welding machine is mainly cylinder, the biggest advantage is low cost, stable operation, good instantaneous following, convenient adjustment, etc., as resistance welding pressure, the cylinder diameter is generally not more than 300mm, the maximum pressure is less than 35000N, the need for greater pressure to do multi-point projection welding, you need to use the cylinder.


In a welding cycle, the formation process of the fusion core of different periods actually need different pressure, such as the initial pre-pressure is small, power pressure increased, late forging pressure is increased, and this pressure conversion requirements are very rapid, such a high demand cylinder pressure is difficult to achieve, then the need for servo pressure way!


Guangdong Hwashi Technology INC. is specialized in the production of series resistance welding machine (spot welding, touch welding, seam welding, row welding, butt welding) and industrial robots (six axis mechanical arm, welding robot, and loading robot, transfer robot, grinding and polishing robot, painting robot, glue robot) research and development, design, production, sales, service as one of the high-tech enterprises.Products are mainly used in household appliances, kitchen appliances, lighting, hardware tools, electrical and electrical, instrumentation, 3C electronic industry, auto and motorcycle parts, military aviation and other fields.According to customer needs, we can develop and customize various welding machines, automatic welding equipment and welding assembly lines, assembly lines, etc., to provide appropriate overall automation solutions for enterprise transformation and upgrading, and help enterprises quickly realize the service of transformation and upgrading from traditional production mode to middle and high-end production mode.
