Oxyacetylene Welding Torch

The oxyacetylene welding torch is used to mix oxygen and acetylene in definite proportions. It also controls the volume of these gases burning at the welding tip, which produces the required type of flame. The torch consists of a handle or body which contains the hose connections for the oxygen and the fuel gas. The torch also … Read more

Plasma Arc Cutting (PAC)

The plasma arc cutting process cuts metal by melting a section of metal with a constricted arc. A high-velocity jet flow of hot ionized gas melts the metal and then removes the molten material to form a kerf. The basic arrangement for a plasma arc cutting torch, similar to the plasma arc welding torch, is shown in figure … Read more

Arc Welding Electrode Classification System

The SMAW electrode classification code contains an E and three numbers, followed by a dash and either “15” or “16” (EXXX15). The E designates that the material is an electrode and the three digits indicate composition. Sometimes there are letters following the three digits; these letters indicate a modification of the standard composition. The “15” or “16” … Read more

Types of Welds

Types of Welds. It is important to distinguish between the joint and the weld. Each must be described to completely describe the weld joint. There are many different types of welds, which are best described by their shape when shown in cross-section. The most popular weld is the fillet weld, named after its cross-sectional shape. … Read more

Carbon Arc Welding (CAW)

Carbon arc welding is a process in which the joining of metals is produced by heating with an arc between a carbon electrode and the work. No shielding is used. Pressure and/or filler metal may or may not be used. Carbon Arc Welding Equipment Electrodes. Carbon arc welding electrodes range in size from 1/8 to 7/8 … Read more
