China's current production of Welding Electrodes the main problem remains the quality and variety development, a number of special electrodes or high quality requirements of the electrode still imported from abroad. In the study of electrode, with our own intellectual property rather the lack of basic technology. Electrode manufacturers for product development into a serious shortage, lack of technological innovation, coupled with domestic universities and research institutions to study the rod out, so this is technically the "lack of confidence" contradictions in the period will be more prominent.
With the development of domestic reform and opening up and China's accession to the World Trade Organization (WTO), in order to meet our technical cooperation with foreign countries and the urgent need for economic exchanges, from welding to increase the performance of foreign and development trends of the introduction, describes the "resistance ground electrodes, "" cobalt-based electrodes, "" iron rod "" stainless steel electrode "" tungsten electrodes, "" nickel-based alloy electrodes, "" Silver rod "" valve rod, "" die electrode "" welding electrode "and the latest standards in order to China's research and development provided by the electrode to sign. In addition, it has added a "pipe Mig Welding Electrode" and "welding wear", etc., in order to better meet the needs of production, scientific research needs.
Method and process of artistic creation is always inextricably linked. As an industrial technology, the emergence of welding the metal arts to meet the new needs of the process means. On the other hand, under the action of the metal in the welding heat generated by the change also to meet the unique beauty of the metal art on the new language of artistic expression needs. In today's metal art, the welding can and is being used as a unique artistic expression to focus on language performance. Welding Art can serve as an independent art form to the branch from the traditional way of separating the metal arts, this is because: First, the welding with art. Welding can produce a rich artistic performance language. Copper Electrode is usually carried out at high temperatures, while the metal at high temperatures will have many wonderful wealth of change: the metal base material color change will occur and thermal deformation (ie, HAZ); wire melted to form a number of beautiful texture; The welding defects in the welding art is often applied. Welding defects is the welding process, resulting in the welded joints do not meet the requirements of design or process deficiencies. The main form of welding cracks, holes, undercut, incomplete penetration, lack of fusion, slag, weld, collapse, pits, burn, inclusions, etc. This is a very interesting phenomenon: the art of welding is usually reflected in the failure of some industrial welding operations into, or hidden in some industrial welding try to avoid welding defects being.
Secondly, the welding is a unique artistic language. All these manifestations of welding defects and heat affected zone, certain norms by the formation of the welding operation, and only by way of welding will produce these artistic language. Welding is the art of surface effects or other metal processing technology can not be difficult to achieve, and thus that art has a unique artistic welding. Use different metal materials, the use of different welding processes, welding of art in different art forms in the metal on its head:
1 Welding Sculpture
Sculptures in the welding, weld and cut marks are not processed as a trace of a passive technology exists, but in a wonderful, essential to the performance to be reflected in the language focus. A welded sculpture, thick seam exposed surface of the sculpture, all kinds of irregular cutting traces the artist has become a beautiful artistic language ... In many cases, due to the pursuit of welded sculpture rough rustic style, metal corrosion, defects are mostly based on the needs of work specifically reservations, therefore, can be welded sculptures often feel a non-crafted, original beauty. Steel sculpture stitching at the bottom of the weld is very thick, solid welding process from point of view, which is obviously not only for the extent of the sculpture strong consideration, in this sculpture, the lower part of the weld has been distorted as a few sculpture, an important factor in the overall aesthetic from its indispensable part. From the sculpture as a whole, both the upper part of the text style, or the lower half of the texture processing, everywhere there are signs of the emergence of welding distortion, the whole works to achieve the overall visual language of unity.
2 Welding mural
If a mural works as a painting, then screen the point, line, surface, black, white, gray or color processing methods can be achieved by Welding Electrode. Various models, a variety of wire materials, the application of different welding processes will be on the screen in different forms. Different colors in different metals, stainless steel bright silver, aluminum sub-silver, glossy black color of carbon steel, titanium steel, bronze, copper, brass ... and on the steel, the different steel when heated at high temperatures there are different color variations, which HAZ different. In addition, the cutting is the art of murals created by welding one of the methods, both used in conjunction with welding, it can be used alone, it all depends on the artist's creative intent and the effect of technology and mastery. These methods described above together, the changes in wealth can be imagined. Works as shown in Figure 3 uses a method of manual plasma cutting, cutting the current use of the heat, the cutting edges of the heat-affected zone, which gives stainless steel white light "pollution" in a circle slightly on the color gradient. Meanwhile, the regulation of the welding specifications, strong spray torch cutting steel melted in the air the moment the cutting edge of the "blow" from the circle formed by random texture, the cutting is completed, the metal cools, solidification of a beautiful cut marks, and the middle flat, polished stainless steel plates forming a texture contrast. The formation of such a random effect with a certain chance, but in certain norms inherent in the welding phenomenon. From the perspective of size, large size mural arts can be used semi-automatic CO2 welding gas arc welding, a small hand-TIG welding can be used.
