Copper Bonded Tungsten Electrode


Tungsten electrodes have been so popular for TIG welding and GTAW welding, including cerium doped, lanthanum doped, yttrium doped, thorium doped, zirconium doped, etc. but besides them, there are many other welding types and electrodes. These days, we encountered the inquiry of spot welding electrodes, which is required with type of copper bonded tungsten electrode. Actually this is a new type, whose history is much shorter than the TIG welding electrodes.


The requirements of copper bonded type are much more accurate than rare earth doped.
1.0   The tungsten part is as pure as 99.95% min.
2.0   The bonding of tungsten and copper is using special welding, so that the welding    layer is without resistance and crack.
3.0   The whole processes of sizes and bonding are applied cold processing by       grounding machine, wire cutting, so that the properties are remained.
4.0   Higher requirements on the sizes and tolerances.

Nowadays, the copper bonded type tungsten electrode is widely used in electronic in car industry, such as Bosch, Denso, Continental, etc. By using spot welding, or resistance welding, the parts with thickness over 3mm, or diameters range from 3mm to 12.5mm and be jointed together.
Copper part in the electrode is applied its high electric conductivity, which can convey the heat to electrode in high speed. Tungsten part receives the heat and the materials between the upper and down electrodes are yielded and squeezed together.
                                       

This kind of bonded electrodes have been many types, the choose of one part is with high electric conductivity, such as copper, silver, etc. the other part is with low electric conductivity, which is to make sure the welding electrode is not left on the surface of welding objectives during welding, the materials can be tungsten, tungsten copper, molybdenum, etc. And copper bonded type tungsten electrode is the most popular one in spot welding.

Introduction to h5.chinatungsten.com

It has been a project takes half a year to finish the structure, key words and content, and finally h5.chinatungsten.com is established.

At the beginning, we came up with the idea of making an h5 version, which actually is an adaptive website for PC, mobiles, pads, and other mobile platforms, so that visitors can review the products, news and information of tungsten through any platforms, instead of website of www.chinatungsten.com, which is best review on the PC.

With the basic idea, we set up a format, which is improved from other adaptive websites, such as www.tungsten-oxide.com. Meanwhile, as for the h5 website is a re-creating of the old version, we analyzed and organized the sitemap, key words and links of www.chinatungsten.com and then finalized the pages of tungsten and molybdenum related products. The new sitemap had been a guideline for the new website, once the content is filled, the website can be loaded and showed for visitors.

After the sitemap with key words, content with pictures had been our main work. Good pictures with company mark and good views of tungsten and molybdenum parts are required. Therefore, we took pictures and photoshoped to a smaller one with width about 300 and 500, which were two images located on the top of a page. And the content went to the main products’ introduction, physical and chemical contents, production methods, categories, MSDS, conflict statement, national standard, image bank, news, price, and other information related. And this page was used as a format for all commodities. Most of the pages were only filled with introduction and will be improved to the format one gradually.

Until Jul. 2020, the h5 version of Chinatungsten has been a website with 17 languages and about 254 pages for each language. In the future, improving and perfecting are main jobs for this site, and adding new key words for new page is also an important part.

If you would like to visit, please click h5 version. Any idea is welcomed.
