Gas Tungsten Arc Welding The Process Gas Tungsten Arc Welding‚ also known as Tungsten Inert Gas Welding‚ is an arc welding process that uses a non-consumable tungsten electrode to produce a weld. The weld area is protected from atmospheric contamination by an inert shielding gas‚ such as argon or helium‚ and filler metal is normally used‚ except in autogenous welds. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and

PROS AND CONS OF UNDERWATER WELDING To briefly present the advantages and disadvantages of underwater welding let us first separate this two compound words‚ the UNDERWATER and WELDING. Underwater is anywhere where this is water‚ either in low or in deep aquatic areas. Now‚ Welding is the action of burning something (particularly a metal) into creating or fixing something with the use of a high temperature to burn down or melt a metallic material so that it can be reformed. Combining this two concepts

Arc Welding (SMAW) is the most widely used welding process in the small scale industries‚ because of its low cost‚ flexibility‚ portability and versatility. Shielded metal arc welding is one type of welding process which uses consumable electrode consist of filler core rod coated with chemicals that will help during welding by providing flux and shielding. This process give pure and clean weldment that has high material deposition rate compared to traditional welding process. The SMAW welding parameters

The topic I am researching for my I-Search is welding. The reason I want to be a welder is because it is something I really enjoy doing and many of my family members are welders. Welding has many ups to the job but it also has its downs to it also.The ups to the job are it pays well in the beginning and the more experience you have the more you make and you also get to admire the work you did. The downs to the job are you tear down your body very quickly and also have the chance to have a pipeline
