Preheating and welding

Welding is basically the mixing of a base metal with filler metal. Filler material is melted at high temperature through a consumable electrode and provides the relevant bonding strength. Filler metal and base metal are bonded together in one solid body. A good quality weld is at least as strong as the base material(s) being joined.
