Working Principle
The workpiece is pressurized and energized between the upper and lower electrodes, and having resistance welding.
When the resistance of the welding part is R (Ω), the welding current is I (A), and the power on time is t (sec), according to the formula: the current I that the metal material with a certain resistance value R passes through within a certain time t heats up due to the resistance, and the heat generated is Q. The metal resistance current is used to heat the molten metal, and then the metal is cooled, crystallized and connected under pressure. This is called resistance welding.
Welding Arm Can Be Customized
Pressurization In The Welding Process
The main working process of this welding machine is composed of four basic procedures: pressurization, welding, maintenance and rest, and additional procedures can be added if necessary.
Pressurization: Before the workpiece starts welding, align the electrode with the welding position, start the welding start switch on the operating handle, open the working air valve of the welding machine, and the compressed air enters the pressurizing cylinder to drive the moving electrode arm to move through the mechanical transmission device, so that the upper and lower electrodes clamp and press the workpiece. This process is called "pressurization". The process parameters are the pressurization time and electrode pressure (appropriate air source pressure is obtained by adjusting the pressure regulating valve).
The shippment is 15 days after getting deopsit, but customized machines should be more than 25 days.
