Advantages of MIG welding

MIG welding (metal arc welding) is a common welding technology with the following advantages:

Low welding cost: The cost of MIG welding is only 40-50% of that of submerged arc welding and manual arc welding.

High production efficiency: The productivity of MIG welding is 1-4 times that of manual arc welding.

Easy to operate: MIG welding uses an open arc, which is not limited to the thickness of the workpiece. It can be welded in all positions and can be welded downward.

High crack resistance of the weld: The weld of MIG welding has low hydrogen and low nitrogen content.

Small deformation after welding: The angular deformation after MIG welding is 5/1000, and the unevenness is only 3/1000.

Small welding spatter: When ultra-low carbon alloy welding wire or flux-cored welding wire is used, or Ar is added to CO2, welding spatter can be reduced.

Low heat input: MIG welding has low heat input, small welding residual stress and deformation, and is suitable for thin plate welding.
The arc itself has a good cathode cleaning effect: MIG arc brazing generally uses DC reverse connection, so no flux is needed, saving costs and processes.
Arc welding, heat is more concentrated: MIG welding arc welding, heat is more concentrated, heating speed is fast, brazed joint stays at high temperature for a short time, the base material does not melt, the heat affected zone is narrow, the metal in the seam area is not easy to produce grain growth, and the organization and performance changes are also small.
MIG brazing is the same as MAG welding: MIG brazing is the same as MAG welding, which can be used for various types of joints and all-position welding. Even in the case of vertical downward, vertical upward and overhead welding, satisfactory results can be obtained. The welding speed can also reach the speed of MIG welding (100cm/min), significantly improving production efficiency and energy saving.
The hardness of the copper alloy weld zone is relatively small: The hardness of the copper alloy weld zone of MIG welding is relatively small, easy to machine and polish, and can be used to replace the flame brass brazing process, with significant economic benefits.
Improved MIG working environment: Traditional arc welding of galvanized steel plates produces a large amount of new steam, which harms the health of operators. MIG brazing smoke and spatter are greatly reduced, which improves the MIG working environment.
In summary, MIG welding technology has been widely used in industrial production due to its high efficiency, low cost and easy operation.
