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.

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

Prof. A.R.Santha Kumar 3.3 Welding and welded connections Welding is the process of joining two pieces of metal by creating a strong metallurgical bond between them by heating or pressure or both. It is distinguished from other forms of mechanical connections‚ such as riveting or bolting‚ which are formed by friction or mechanical interlocking. It is one of the oldest and reliable methods of joining. Welding offers many advantages over bolting and riveting. Welding enables direct transfer of

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

In other words‚ it expressed the effects of a person’s “economic‚ social and work status” (Skolnik‚ 2013‚ p. 20). For example‚ LaJoe experienced negative socio-economic impacts after she lost her Public Aid. She had stayed home with her children for the past seven years and lacked the skillset required to enter the already limited job market (Kotlowitz‚ 1992). The lack of skill set puts her at a disadvantage in terms of socio-economic measures as she faced both economic and employment instability

would just say welding but that time I was like 6 years old. I didn’t know what it was but curious cause the word welding for me was interesting. As I grew up I started working for my Uncle which had a company of masonry which I was a labor tough work but it paid off. I worked for 4 years with my uncle then thought to weld the thing my dad had been doing for many years and what he wouldn’t tell me. But last year it all started when my dad decided we should run a company of welding ourselves and now
