Underwater welding‚ Underwater welding was invented in Russia in 1932 by Konstantin Konstanovich Khrenov and used it throughout the soviet navy. During WWII‚ the American Cyril D. Jensen‚ professor of engineering at Lehigh university‚ developed the USA’s own underwater welding programs and created 2 U.S. patents in the field. (Agnew‚ 1999-2013) Under water is a technique that is employed in various engineering projects‚ where in welding is carried out under the surface of the water. Underwater

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

NO THANKSGET THE APP how heat affects metal when it is being welded (peasecha) Charles Pease 3-29-16 English 10 How heat produced from welding affects metal The heat produced from the welding process can cause deformation and can also cause changes in the metal at a molecular level. This can make the metal brittle and even deform it. When the arc is struck and the metal starts to become molten it reaches temperatures in an excess of 8‚000 degrees fahrenheit and such a large input of heat

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

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.
