Aluminium Alloy 7039 Anoop C A‚ Pawan Kumar Department of Mechanical Engineering‚ NIT Calicut (Kerala)‚ India VRDE‚ Defence Research and Development Organization‚ Ahmednagar (MS)‚ India Vainarman et al. [2] reported that the use of pulsed arc welding in place of conventional GTAW increases the output by 200–400%‚ reduces consumption of argon by three to ten times‚ and also reduces the cost of 1 m weld deposition by three to five times. The aim of pulsing is mainly to achieve maximum penetration

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

set in stone for me to see the welding lab. After meeting and learning about all the different opportunities there are after attending this school‚ we finally got to meet with Mr. Jezylo and Mr. Paulsen. As soon as I entered the shop I instantly felt at home. The humming of the welding machines‚ the loud crash of metal falling to the floor after being cut‚ and the sparks flying as students are welding were amazing. I could’ve spent forever in there learning about welding and what it takes to become

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
