The original idea stems from the 1920s of CO2 welding process, weld pores problem is not resolved, however, causing the CO2 welding can not be used. Until the early 1950s, the development of Welding Electrode Materialtechnology to solve the problem of CO2 Welding Wire Manufacturers, developed a series of wire in the Si-Mn, which makes CO2 welding process to obtain a practical value. After that, according to the performance of structural materials, have appeared in wires of different groups of ingredients, to meet the diverse needs of CO2 welding.
CO2 welding process utility into society brought great wealth, on the one hand, because the CO2 gas is inexpensive, easy to obtain, on the other hand is due to the high CO2 welding of metal deposition efficiency, semi-automatic CO2 welding, for example, its efficiency manual arc welding of three to five times.

Submerged arc welding wire ,welding wire and flux submerged arc welding consumable materials, welding wire and flux can choose to tie in with the submerged arc welding of carbon steel to high nickel alloys a variety of metal materials. The selection of the submerged arc Welding Wire is necessary to consider the impact of the flux composition, but also consider the impact of the base metal. , You can use a flux in order to get different types of weld composition and mechanical properties (mainly the smelting flux) and several wire with a wire with several flux can also be used (mainly agglomerated flux) with.
A low carbon steel and low alloy steel wire submerged arc welding of low carbon and low alloy commonly used in wire, the following three categories: â‘  The low manganese welding wire often with high manganese flux for low-carbon steel with low strength, low alloy steel welding. â‘¡ manganese welding wire is mainly used for low alloy steel, but also with low Mn flux for low-carbon steel welding. â‘¢ high manganese wire (H10Mn2H08Mn2Si,) for the low alloy steel welding.
B, High Strength Low Alloy Steel Wire low alloy high strength steel wire containing Mn1%, containing Mo0.3% -0.8%, for high strength low alloy high strength steel welding. In addition, high strength low alloy steel composition with the use of performance requirements, but also to the wire in the Ni, Cr, V, and RE elements to improve the weld properties. The weld metal strength level 590Mpa use of the Mn-Mo wire.
Stainless steel wire stainless steel welding, the composition of the wire with welded stainless steel components are basically the same. Can be H0Cr14H1Cr13H1Cr17 such as wire, welded chrome-nickel stainless steel, can be used H0Cr19Ni9H0Cr19Ni9Ti such as welding of chromium stainless steel wire; of ultra-low carbon wire should be used when welding low carbon stainless steel. The flux can be a melting-type or sintered, requiring that the Welding Flux of oxidizing smaller, in order to reduce the burning of the alloying elements.
