The spot welding machine uses the high temperature arc generated by the positive and negative poles in an instant short circuit to melt the solder on the welding electrode and the material to be welded, so that the contacted objects can be combined. The structure of the spot welder is very simple, that is, a high-power transformer. Current spot welding machines are generally divided into two types according to the type of output power, one is AC power and the other is DC power. Both use the principle of inductance. When the inductance is increased and a large voltage change occurs when it is turned on and off, the high voltage arc generated by the positive and negative poles when the short circuit occurs can be used to melt the solder on the electrode. Make them achieve the purpose of atomic bonding.
I. Mold industry 1, lithium battery industry 2, stamping mold 3, die casting mold 4, rubber mold 5, copper alloy mold 6, injection mold spot welding machine after welding repair, the mold can be subjected to various mechanical processing and heat treatment and nitriding treatment .
Second, the spot welding machine in the casting industry also has a good performance in terms of casting defects. Then the air holes, slag holes, shrinkage holes, etc. can be quickly and accurately repaired during the casting process.
It has excellent repairing effects for ductile iron, gray iron, and stainless steel defects, fast welding repair speed, no color difference or small color difference after welding, which is more suitable for the needs of factory-scale production. It is also recognized that the difficult to repair machine tool track surface has also been ideally solved.
Third, a variety of workpiece spare parts repair industry, spot welding machines can complete the repair of shafts and teeth and other workpieces.
