Fundamentals of Welding

Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals. The completed welded joint is referred to as weldment. It is a high heat process which melts the base material. Heat at a high temperature causes a weld pool of molten material which cools to form the join, which can be stronger than the parent metal. Pressure can also be used to produce a weld, either alongside the heat or by itself.

Welding is usually used on metals and thermoplastics. Some materials require the use of specific process and techniques. Welders work with aluminum, cast iron, stainless steel, and titanium. Due to its high corrosion resistance and good electrical conductivity, aluminum is being used in a growing number of industrial applications.

Also there are some material combinations that cannot be welded successfully. They are aluminum and steel (carbon or stainless steel), aluminum and copper, and titanium and steel.
