Do you need skilled operators when operating an intermediate frequency spot welder?
Before welding, it mainly finds suitable welding conditions at the beginning, and adjusts the suitable parameters according to the workpiece to be welded, then the control device (that is, the controller) will perform welding according to the set conditions, in order to find good welding conditions Requires people who are familiar with welding technology, but after setting good welding conditions, even workers without operating experience can operate it.
But one thing worthy of our attention and learning is that during the operation, the surface of the electrode will form a white medium on its surface as the number of welding increases. If it is not ground in time, it will increase the resistance and affect the quality of the solder joints. In order to guarantee the welding quality at all times, a file or electrode dresser should be used for grinding regularly.
During spot welding, there is a set of standard welding condition tables for mild steel, stainless steel, and aluminum alloy materials. After actual operation according to the welding condition table, if there is a problem with the nugget diameter or welding strength, then Modify the set value before and after this value to find out the welding conditions.
But if it is the same type of metal, it is also necessary to continuously improve the welding conditions according to its plate thickness, surface condition and target size of the nugget diameter of the joint, surface condition after welding and other requirements.
But the most important thing to pay attention to is safety first!
