1, the welding between the film and the film. Including welding, side welding, the center through fusion welding, the center hole of 4 kinds of technology fusion welding methods. 2, wire and Welding Wire . Including wire and wire welding, cross-weld, parallel to the lap welding, T-4 kinds of welding process method. 3, wire welding of bulk components. Using laser welding can be successfully achieved with the block device wire connection, block elements can be any size. It should be noted in the welding geometry of filamentous components. 4, different metal welding. Different types of metal welded to resolve the weldability and welding parameters can range. Laser welding between different materials, only certain combinations of materials is possible. Laser soldering should not be used to connect some components of the laser welding, but can use the laser as a heat source, the purposes of soldering and brazing, laser welding also has the advantage. By brazing in different ways, which is mainly used for laser soldering of printed circuit board welding, especially useful in the chip component assembly.
At present, the main welding industry manufacturers, the basic joint ventures, wholly foreign-owned and domestic private enterprises. Some of the planned economy state-owned giant, almost annihilated!
With the past planned economy period, compared the pattern of the Welding Wire has been people have changed.
We take a look at the pattern of welding industry is:
1, Guangdong, especially 30 years ago, Shenzhen was a small fishing village, gradually become the production base of inverter welding machine; said in Shenzhen, inverter welding machine almost all of the accessories, you can bulk buy, as long as there is a site, recruitment of more workers will be assembled debugging, you can batch inverter welding machine ... ...;
2, Shanghai, Hongo home, a little welding scale manufacturing enterprises, it seems that not much. Shanghai welding industry can represent the size of the weld that some manufacturing companies, the boss is not a native of Shanghai seems to have most of the ... ...;
3, Chengdu, Sichuan, Chengdu Welding Institute because, as the Institute of guys, and then came up with a large group of manufacturing companies belonging to the welding of Chengdu. Now, the gang bosses are rich, but into the welding industry where the impact and status has diminished. Have affected the welding industry for several decades in China China Welding Exposition, is facing new challenges;
4, Tangshan, a city built after the earthquake, in recent years, the welding of Tangshan Industrial Park is taking shape climate;
5, Harbin, Harbin Institute of welding expertise in one of the earliest, fragrant peaches and plums, the impact of the welding industry, with some welding manufacturing enterprises should not be compared. Harbin Welding Institute into the welding with the same, because the Restructuring, the original possessor of the national money into the enterprises and institutions, in the welding industry's influence and position in the less? The difference is that Kazakhstan did not welded by a similar differentiation in Chengdu so many manufacturers out of welding, welding of the Kazakh elite a gang-related, but added Beijing Essen exhibition will toss up;
6, Changzhou, Jiangsu, for decades, the basic welding torch cutting torch and accessories for the mainstream;
7 Renqiu in the welding torch and accessories with the formation of south and north, Changzhou and Wenzhou;
8, Wenzhou, Ningbo, in the early years of the welding industry in decline;
Question worth considering: the best gun of domestic brands, but not in Changzhou, Wenzhou, and the homogenization of products Renqiu the gathering place for many companies!
Three decades east, west four years, the market relentlessly. Some companies, after decades of ups and downs, there are no major up, did not die ... ... in another ten or twenty years, the Chinese welding industry, how will the pattern change? We will wait and see!
