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

Welding of Joint : * Clean the joint surface. * Preheat the joint area of shell ( 1m lg ) to 150 deg * Welding electrodes are to be preheated * Complete the root run on the outer surface of the joint side with 2.5mm electrode. * Next with 4mm electrode & then 5mm & 6 mm electrodes. * Gouge & remove the root run weld from the inner surface of the joint‚ check with Dye penetrant for any cracks and start the root run inside. * Complete the inside welding.

Bechtel Power Corporation’s Use of Objective Welding Tests Objective tests measure both your ability to remember facts and figures and your understanding of materials and procedures. I believe that this case is not based on race. Mr. Ligon was hired based on his testing qualifying him to perform more difficult welding procedures‚ AT-LH. The reason why he was required to retest is because he improperly prepared a weld. The retesting was provided by the corporation and retesting and training

resistance spot welding process parameters on the shear-tensile strength of the welded joints of Inconel alloy 625 was investigated. Experimental study using full factorial design of the welding current‚ welding time‚ and electrode force parameters was conducted. In order to identify the influence of each parameter and their interaction a general linear model and a second order model using response surface method was developed. Nonlinear correlation was observed between the welding process parameters
