Electric arc welding is a fusion welding process. Welding heat is obtained from an electric arc between the work (or base metal) and electrode. An electric arc is produced ..
A welding robot is an automated machine that performs welding tasks. Welding and robots go hand in hand. So it’s no surprise that robotic welding applications ..
Gas Tungsten Arc Welding (GTAW), also known as TIG (Tungsten Inert Gas) welding, the filler metal is supplied from a filler wire as shown in the figure below. ..
Gas Metal Arc Welding (GMAW) is also called metal inert gas (MIG) welding. In the gas metal arc welding process, the weld area is shielded by an inert atmosphere ..
Plasma Arc Welding (PAW) is an arc welding process; an entire plasma arc is produced and directed towards the weld area. The arc is stable and reaches temperatures ..
Basic Weld Symbols The basic weld symbols according to IS: 813 – 1961 (reaffirmed 1991) are shown below with sectional representation and symbol in the tabular ..
Shielded Metal-arc Welding (SMAW) is the simplest and used for many joining processes. More than 50% of industrial and maintenance welding currently is performed ..
The process of welding and cutting of metals involve the application of high heat energy to the objects being welded or cut. This high amount of heat energy for welding ..
There are a number of welding processes available; however, their application is dictated by the mechanical properties, type of welded joints, their quality required ..
Thermit welding is the joining process in which heat required for melting and joining of components is obtained due to the exothermic chemical reaction. When the initiation ..
The ease with which welding of a given material can be done without producing any defect is called Weldability. Weldability can also be defined as the capability ..
Arc Welding Processes In arc welding process, an electric arc between an electrode and a workpiece or between two electrodes is utilized to weld base metals. ..
Defects in welding joints can be classified into two types as external and internal defects. 1. External Defects in welding: External defects of welding include ..
The operator beginning his career in operating arc welding machines must go through and become familiar with these general safety recommendations to avoid accidents ..
