BASIC PRINCIPLES OF WELDING

A weld1 can be defined as a coalescence2 of metals produced by heating to a suitable temperature with or without the application of pressure, and with or without the use of a filler material.3

In fusion welding4 a heat source generates sufficient heat to create and maintain a molten pool of metal of the required size. The heat may be supplied by electricity or by a gas flame. Electric resistance welding5 can be considered fusion welding because some molten metal is formed.

Solid-phase processes6 produce welds without melting the base material and without the addition of a filler metal. Pressure is always employed, and generally some heat is provided

The electric arc used in welding is a high-current, low-voltage discharge7 generally in the range 10-2,000 amperes at 10-50 volts. An arc column8 is complex but, broadly speaking, consists of a cathode that emits electrons, a gas plasma for current conduction, and an anode region that becomes comparatively hotter than the cathode due to electron bombardment. Therefore, the electrode, if consumable, is made positive and, if non-consumable, is made negative. A direct current (dc) arc is usually used, but alternating current (ac) arcs can be employed.
