Mechanical engineer
Mechanical engineering is one of the broadest engineering disciplines. Mechanical engineers research, design, develop, build, and test mechanical and thermal devices, including tools, engines, and machines. Duties Mechanical engineers typically…
Gas Metal-arc Welding (GMAW)
Gas metal-arc welding (GMAW) also called as metal inert-gas (MIG) welding, In Gas metal-arc welding process the weld area is shielded by an effectively inert atmosphere of argon, helium, carbon dioxide or various other gas…
Submerged-arc Welding (SAW)
In Submerged-arc Welding (SAW), the weld arc is shielded by a granular flux consisting of lime, silica, manganese oxide, calcium fluoride and other compounds. The flux is fed into the weld…
Brazing & Difference between Brazing and Soldering
Brazing: Brazing is a metal joining processes, which is done by using the filler metal. It is heated above the melting point and distributed between two or more fitting parts by…
Shielded Metal-arc Welding (SMAW)
Shielded metal arc welding (SMAW), also known as manual metal arc (MMA) welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld.…
Defects in Welding Joints: Internal and External
Defects in welding joints can be classified into two types as external and internal defects. · External Defects in Welding · Internal Defects in Welding 1. External Defects in welding: External…
Electrogas Welding (EGW)
Electrogas welding (EGW) is an vertical positioned arc welding process, is used for welding the edges of sections vertically and in one pass with the pieces placed edge to edge (butt joint). It…
Flux-cored Arc Welding (FCAW)
The flux-cored arc welding process is shown in image below is similar to Gas Metal-arc Welding, except that the electrode is tubular in shape and is filled with flux. Cored electrodes produce…
Plasma-arc Welding (PAW)
In Plasma-arc Welding (PAW) is an arc welding process, a concentrated plasma arc is produced and directed towards the weld area. The arc is stable and reaches temperatures as high…
Electroslag Welding (ESW)
Electroslag welding (ESW) applications are similar to electrogas welding. The main difference is that the arc is started between the electrode tip and the bottom of the part to be welded. Flux is added, which then…
