电焊机 是指用半成品制造焊接件所需的机器设备、夹具和固定装置。焊接位置或工位是一组焊接设备，用于需要焊工一定程度参与的操作。一条焊接线结合了多个焊接站。
焊接站可用于电弧焊、电阻焊、气焊、电子束焊或其他方法。焊接设备包括 ARC棒焊机，电源，直接用于进行焊接过程的设备，用于快速组装待焊零件，在焊接过程中固定零件以及防止或减少焊接物品翘曲的夹具和固定装置，用于焊接的辅助设备焊接过程中的运输部件以及用于安装和运输焊接设备以及焊工使用的各种其他工具。焊接过程中还使用了各种用于控制焊接质量的运输工具和仪器。焊接设备的技术特点由选择的焊接方法、生产类型和机械化程度决定，即是进行手工、半自动还是自动焊接。
焊接站是生产区域的一部分，电源、载流导体以及必要的夹具、固定装置和焊工工具都位于该区域。为了保护该区域的人员免受辐射，焊接站被窗帘或面板封闭。固定自动化工位广泛应用于现代制造工艺；此类站位于制造车间。移动站用于现场焊接建筑和维修工作中的大型物体。
焊工。
焊接站包括电源和用于在焊接过程中调节电弧的设备。用于焊接的电源应提供方便、连续或步进控制，并且必须满足电机和设备的一般要求。 交直流氩弧焊机、变压器、发电机、整流器用于电焊；气体发生器用于气焊。电源可以是单位置或多位置类型、用于连续、长期运行的固定装置或用于短期工作的小型便携式装置。
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.
