The laser used in China up mode with wire, from the material points can be divided into the following categories:

1, stainless steel wire

Advantages: cheap;

Disadvantages: low hardness, Welding Wire spots apparent;
 
Uses: mainly used for training and exercises.
                                  
2, mold base metal wire drawing or argon

Advantages: cheap, variety (manufacturer from China, Taiwan, Korea and Japan);

Disadvantages: not good melting, welding spots apparent cracks prone to blisters and other bad quality;
                     
(Type of wire with the base metal before welding performance closer, but after high-energy laser melting, then cooled in air after curing, the metallographic structure of the welding mold base material with the metallurgical structure is inconsistent.)

Purpose: mold used for less demanding quality repair.
 
3, the laser welding wire mode-specific (laser wire)
 
Advantages: good melting, Flux Cored Welding Wires spots is not obvious, is not prone to blisters cracks and other bad quality;
          
(Type of wire with a variety of alloy composition, after the high-energy laser melting, and then naturally cooled after curing, the metallographic structure of the welding mold base material with the same metallographic structure, after the welding performance with the same base metal mold .)

Disadvantages: less brand (currently only German production, and only three to five manufacturers);
 
Purpose: mold used for high quality repair.
 
German production of laser welding is also divided into two categories:

One is based on argon produced by the wire electrode process, strictly speaking, can not be used in laser welding mode; the other is specifically developed for laser welding and laser welding wire special (such as DSI and Quada laser welding).

Solid Welding Supplies for gas shielded metal structure along with the development of welding technology and growth in China's "Plan" and the "Plan" period, in order to meet the national key projects of large machinery manufacturing technology and equipment requirements, the introduction of foreign advanced welding technology and equipment, machinery for large-scale backbone enterprises in technological innovation, China's large metal structure manufacturing enterprises, with the United States, Germany, Japan and other countries, multinational companies manufacturing large metal structure, bulk purchase of foreign gas welding equipment, consumables and other equipment, and the welder training. We mature with foreign gas shielded arc welding technology and production processes, formed a large metal structure welding gas production capacity, a fundamental change in the metal structure of the manufacturing technology, promoting China's gas shielded arc welding technology. Since the early 1990s, nearly 10 years to 1992, the 1st "National CO2 welding technology promotion and application of exchange" as an opportunity, gas metal arc welding technology in the structure of the industry promote the use of the work to flourish, development and application of arc welding technology increased capacity, the application of mechanical work from large to small and medium enterprises to promote businesses, and large gas welding machinery enterprise applications from co-production, promotion to general production, Gas Shielded Welding Wire equipment, welding consumables, accessories basic the realization of domestic supply, a group of welding equipment, welding materials, shielding gases and accessories manufacturers to seize the market opportunity to grow quickly, and gradually formed a gas shielded arc welding industry.
