The most commonly used gas shielded welding consumables are certainly different from the material being welded. The silicon content and the manganese content in the wire are higher than those in the material. And the sulfur content inside the wire is much lower than the sulfur content of the base material being welded. Here, the role of silicon manganese is in the welding arc, in the welding bath for deoxidation of the chemical reaction, the other silicon manganese infiltration of the base metal can also improve the strength and plastic of the weld metal.
This is a bicker
First said that the base material, copper, aluminum, carbon steel, stainless steel, cast iron, titanium ,,,,,
Say welding material, ,,,,,,,,
The welding method is then discussed
Then arrange the combination.
Can be welded, divided into a class.
Can not be welded, divided into a class.
1, in most cases, sheet material and welding material is certainly not the same, the two are not comparable.
2, the plate is usually made of standard size flat rectangular building material board, for walls, ceilings or floor components. Also refers to the forging, rolling or casting made of metal plate. Divided into thin plate, medium plate, thick plate, special thick plate, usually made of standard size flat rectangular building material board.
3, the wire is used as a filler metal or as a conductive wire welding material. In the gas welding and tungsten gas protection arc welding, the wire used as a filler metal; in submerged arc welding, electroslag welding and other melting gas protection arc welding, the welding wire is both filled with metal, but also conductive electrodes. The surface of the wire is not coated with an oxidative flux.

??? The metallographic structure of the weld metal is generally a coarse tissue, which is very poor in mechanical properties. The structure of the base material to be welded is generally fibrous forged tissue, and the mechanical properties are much better. However, due to the weld metal into a certain amount of silicon manganese, the strength of plastic have been improved. In general, the weld metal is much better mechanical than the low carbon steel base metal.
