How To Describe Arc Welding. The definition of arc welding is a welding process that is used for welding the metals with the help of electricity to generate sufficient heat for softening the metal as well as when the softened metal is cooled then the metals will be welded. Since the joining is an inter-mixture of metals the final weld joint potentially has the same strength properties as the metal of the parts.
Upon cooling and solidification a metallurgical bond is created. It has its usage in industrial fabrication and the construction of steel structures. This article will describe the use of flux-coated welding rods and a simple transformer type cracker box welding machine.
A welding arc is maintained when the welding current is forced across a gap between the electrode tip and the base metal.
In arc welding processes a number of potential electrocution sources can be identified. By applying intense heat metal at the joint between two parts is melted and caused to intermix - directly or more commonly with an intermediate molten filler metal. The scratching method is easier for beginners and when using an AC machine. With curve 1 the arc striking voltage is E and the arc recovery time is t 1In the case of curve 2 with the same re-igniting voltage E the arc recovery time t 2 is considerably longer than t 1.
