焊接变压器用于匹配焊接电路和电源的参数；它还用作电压调节器。印刷 螺柱焊接机, the voltage is regulated mechanically or electrically. In the former case, the distance between the primary and secondary windings is altered. Electrical regulation is accomplished by changing the control currents in supplementary windings, located on the upper and middle field frames of the transformer. In this method, the secondary winding is divided into two sections, one of which is located in the upper window of the transformer. Such a transformer is capable of producing various no-load voltages without a change in the turn ratio; this property is required for welding adjustments. Welding transformers used in resistance welding have a minimum short-circuit resistance and a secondary winding that usually consists of one or two turns. Changes in secondary voltage are achieved by tapping sections of the turns of the primary winding.
Air Plasma Cutting Machines are becoming an increasingly common tool in many industries such as metal fabrication, construction and automotive repair. This tool is able to cut through several types of metal including steel, copper, brass and aluminium by generating an extremely high-temperature, electrical channel of ionised gas otherwise known as plasma.
To create the 4th matter – the plasma – the cutter sends an electric arc through a gas, (either oxygen, nitrogen or argon) which rapidly increases the heat levels to the point where it goes beyond a solid, liquid or gas and becomes plasma. The machine will then use the plasma to transfer the energy to any conductive metal, allowing it to cut through with very little or no resistance. This method results in a clean, fast cutting process.
Laser Welding Machine or laser beam welding is one of the most widely known, accurate types of welding processes. It is a non-contact, high power density welding process used to join multiple pieces of material together using energy emanating from a laser beam. Aerospace, defense and military, medical, electronics, petrochemical refining, communications and energy are some of the common areas where laser welding techniques are applied extensively.
- Deep weld penetration and minimized heat inputs are the special characteristics that set laser welded products apart from other conventional welding processes;
- Pulsed or continuous laser beams are used depending upon the welding application;
- There are many types of laser welding available and the most popular types include Nd:YAG laser welding, CO2 laser welding, and diode pumped laser welding;
- Deep narrow welds, without any distortion, and minimal heat-affected zones can be obtained using our laser welding machines that can function at increased travel speeds.
