[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

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

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

Congenital Heart Defects in Children Imagine giving birth to a beautiful‚ healthy looking‚ baby girl and holding her in your arms for the first time. Now imagine a doctor telling you that this little miracle has a possible life threatening congenital heart defect. I can because this happened to me. My daughter suffers from three different congenital heart defects. According to the American Medical Association Family Medical Guide‚ about 8 out of every 1‚000 children are born with heart abnormalities

Defects Like most expectant parents‚ you probably alternate between fantasies about a healthy baby and worries that your baby will have a health problem. Or perhaps you’ve been told throughprenatal screening that your baby might be born with a birth defect. Many parents assume that all birth defects are severe or even fatal‚ but the fact is that many are treatable‚ often immediately after birth — and sometimes even before the baby is born. It’s especially important to know the risk factors
