| MIG SG welding of galvanized panels |
| In order to create good quality repair welding joints, follow
the indications below: |
| t
| The current intensity (amperage) in the welding transformer
must be increased. |
| t
| At the same time, the advancement of the wire must be adjusted,
as the increase of the voltage only causes a higher voltaic arch (higher
penetration, more porosity in the seam structure). |
| t
| Use cylindrical gas nozzles instead of conical ones (the projection
of liquid metal in a narrow gas nozzle causes the formation of pores). |
| t
| Place the burner at approximately 12 mm above the welding product,
in a neutral position, up to an angular position of 10°. |
| t
| The quality of the wire to be used must be the „mildest“ possible. |
| t
| As gas, CO2 or shielding gas may be used. |
