Selection of welding materials
At present, MIG welding is mainly used for welding aluminum, magnesium and their alloys; MAG is mainly used for welding stainless steel, low carbon steel and low alloy steel; CO2 is mainly used for carbon steel welding.
① Selection of protective gas
MIG usually uses pure AR and pure he, or a mixture of them in a certain proportion. When MIG welding aluminum alloy,
Different mixing ratio of AR and he has different effects on weld shape, including penetration, width and reinforcement.
MAG usually uses Ar + O2, Ar + CO2, or Ar + CO2 + O2 mixture.
Ar + O2 is generally used for stainless steel welding, and the amount of O2 is 1% - 5%; Ar + CO2 is mainly used for welding carbon steel and alloy structural steel, and the amount of CO2 is generally controlled in the range of 5% - 30%; Ar + CO2 is generally used for welding low carbon steel and low alloy steel
+ O2 mixed gas.
CO2 is the direct use of high-purity carbon dioxide gas as protective gas, its purity is more than 99.98%.
② Selection of welding wire
MIG welding: the chemical composition of the welding wire used shall be the same as that of the base metal. The diameter of the welding wire is usually in the range of 0.8-2.4mm. Before use, it must be strictly cleaned chemically or mechanically.
MAG welding: high manganese and high silicon welding wire should be used when welding with strong oxidizing gas mixture; For argon rich gas mixture, low manganese and low silicon welding wire should be used;
CO2 welding: add a certain amount of deoxidizer into the welding wire, such as Al (aluminum), Ti (titanium), Si (silicon) and Mn (manganese). Therefore, h08mn2si welding wire is widely used, which contains Mn and Si.
Note: (h08mn2si is low alloy carbon steel for welding. H stands for welding wire; 08 is the carbon content, which is about 0.08%; 2 represents that the content of manganese is about 2%; It also contains about 0.6% silicon. Welding steel includes: carbon steel for welding, alloy steel for welding and stainless steel for welding, etc., and the symbol "H" is added at the head of all kinds of welding steel. For example: "H08", "h08mn2si", "h1cr18ni9", etc.)
Welding wire for carbon steel: at present, the most widely used welding wire is ER50-6 (American Standard ER70S-6), followed by er50-3
(er70s3).
ER50-6 (ER70S-6) welding wire and filler wire are suitable for both single pass and multi pass welding. They are particularly suitable for sheet metal where smooth weld passes are expected and for sections and plates with moderate amounts of rust or hot-rolled scale. In CO2 shielded welding or MAG welding, these wires are allowed to use a higher current range.
Stainless steel welding wire: MAG, MIG automatic welding wire has bright semi hard state, soft state disk or barrel. Its brand is more, generally which type of base metal is, use the corresponding model of welding wire.
Common are: er304, er308l, er309 grade welding wire.
If the requirements are not strict, some welding wire grades can also be used; If the requirements are strict, the same type of welding wire must be used. For example, stainless steel welding wire is used in the food industry. Because of safety problems, the welding wire with consistent or higher performance than the base metal and without affecting food safety must be used. And different welding wire, the weld metal crystal after welding will be different, so the strength, toughness and other mechanical properties of the weld will also be different.
