I used the Zhenjiang Seiko welding
It is possible that the current is too small, or that there is a foreign object in the metal contact surface or that the contact surface is uneven. It is possible that the power of the spot welder is not enough.
First of all, to confirm whether the welding machine parameter is not set or the equipment power is not enough.When the electrode size is suitable, the welding current is transferred to the maximum and the welding is not good, so the equipment with high power should be considered.
There is the reason of weld spot welding welding parameters did not set, the first parameter test, after passing the test procedure as laid down in the production process, in accordance with the procedures.The welding parameters include 1. compression time, 2. welding time, 3. maintenance time and 4. rest time. But there are two important parameters: one is to set the appropriate electrode pressure, to ensure that can compress the workpieces to be welded; the other is the set welding current to the right, it can guarantee the molten metal to be welded. On this basis, the above four process parameters adjusted, you can firmly welded.
