Tungsten electrode, which is made of tungsten electrode with high melting point, corrosion resistance, high density, good thermal conductivity and conductive material. Tungsten Electrodes are widely used for welding in their properties. Tungsten electrode grinding or polishing and black bar. The final color is different, you can distinguish the difference. In the tungsten electrode, more importantly, their final color is different, tungsten content is also different. When welding, select the correct tungsten electrode, make welding easier, it is important to get high quality welding. Some important factors to consider in making the right choice are power (inverter or transformer), welding material (steel, aluminum or stainless steel) and the type of material thickness.

The technical level of China's carton packaging machinery, as a whole, is now about 20 years behind that of foreign advanced countries. It is evident in the competition in product development, performance, quality, reliability, and service. Disadvantages.
Among these, higher requirements are placed on the integration and efficiency of carton packaging production machinery, that is, more integrated machines are needed. At present, China's carton machinery and equipment are relatively decentralized, and there are not many equipments with integrated functions. Packaging machinery refers to machinery that can complete all or part of the product and product packaging process. The use of mechanical packaging products has many advantages, which can not only increase productivity, reduce labor intensity, but also meet the needs of large-scale production and meet the requirements of cleanliness and hygiene. From this perspective, the prospects for the development of packaging machinery are very broad, but if high-end core technologies are not available, we can only make money and work for others.
The packaging and printing treatment process is more scientific and applicable, and the performance and effectiveness of the packaging have changed significantly. For example, in the past, wax coating and film lamination in the packaging surface treatment have been gradually replaced by surface gluing (spray-bonding), and the anti-counterfeit packaging production process has changed from partial printing or production to monolithic printing and production. Security.
The role of motion control products and technologies in packaging machinery is mainly to achieve precise position control and strict speed synchronization requirements. It is mainly used for handling, conveying, marking, palletizing, and depalletizing. Therefore, it is clear that motion control technology is one of the key factors that distinguish high, medium and low-end packaging machinery. The technical support for this packaging machinery upgrade has also become a bottleneck for the development of domestic high-end packaging machinery.
Due to the characteristics of tungsten, making it very suitable for TIG welding and other similar work of this electrode material. The addition of rare earth oxides to the metal tungsten to stimulate its electron work function, making the tungsten electrode welding performance can be improved: the arc of the arc better performance, better stability of the arc column, the electrode burn rate is smaller. Conventional rare earth additives are cerium oxide, lanthanum oxide, zirconium oxide, yttrium oxide and thorium oxide. Tungsten Inert Gas (TIG) welding is a popular type of welding that utilizes tungsten electrodes to join various metals. The tungsten electrode is a critical component in the process, as it channels the current required to establish the arc. The tungsten electrodes can be alloyed with a variety of metals. Different types and sizes of electrodes are used for different types of welds and materials, and welders develop preferences based on welding style and project. Certain electrode types perform better with alternating current (AC) as opposed to direct current (DC). Electrodes are shipped without a ground tip. If grinding a tip, make a tight, sharp point in order to achieve a powerful and precise arc to ensure a clean weld.tungsten electrodes are used when arc welding with the Tungsten Inert gas (TIG) process or when plasma welding. In both processes the electrode, arc and weld pool are protected from atmospheric contamination by an inert gas. A tungsten electrode is used because it can withstand very high temperatures with minimal melting or erosion. Electrodes are made by powder metallurgy and are formed to size after sintering.
TIG welding electrodes usually contain small quantities of other metallic oxides which can offer the following benefits:-
facilitate arc starting
increase arc stability
improve current-carrying capacity of the rod.
reduce the risk of weld contamination
increase electrode life
The trend of polarized development of domestic carton packaging machinery is obvious
Looking at the development of paper packaging printing technology, there are several new features: the development of single-layer materials in the direction of multi-layered materials; the coexistence of multiple printing methods such as offset printing, gravure printing, flexo printing, and screen printing, among which flexo printing will The fastest growing; sheetfed to web and stand-alone to the direction of online production, to complete the supply of complete sets of equipment; comprehensive application of a variety of related new technologies continuously optimize the entire production system; more and more increasingly strict environmental protection Constraints with health standards.
