How does the type of metal being welding influence electrode selection?

The type of metal being welded is a primary factor influencing electrode selection because the electrode's composition must be compatible with the base metal to achieve a strong, sound weld. The electrode's metal composition should be similar to that of the base metal to ensure proper fusion and prevent metallurgical incompatibilities. If the electrode and base metal are dissimilar, the weld may be weak, brittle, or prone to cracking or corrosion. For example, when wel....
