Can I weld mild steel to high yield steel?


Frequently asked questions

Yes, provided that the welding procedure, particularly any preheat, is designed for the high yield steel. This may mean using basic low hydrogen MMA (SMA) consumables. It is also a convention that the weld metal matches the strength of the weaker of the two components although this is not invariably the case. However, it must be recognised that the strength of such a joint will always be limited by the magnitude of the mechanical properties of the mild steel.
