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

THESIS ESSAY ASSIGNMENT What is a sweatshop really? Well the American Heritage Dictionary defines a sweatshop as a shop or factory in which employees work long hours at low wages under poor conditions. If someone had heard this definition of sweatshops they would go straight to the assumption that sweatshops are not good. But they do have some good in them. They keep workers away from bad things such as prostitution and crimes. They also boost the countries economy and give them a means

Fusion welding and non-fusion welding Fusion welding is defined as a welding process of using heat by melting the base of metals in order to joint similar types of metals together. Filler is used in this welding process to provide bulk and strength to the welded joint [1]. Whereas non-fusion welding which is known also as solid state welding is a welding process where a particular amount of heat is applied to the joining metals which essentially below the melting point of the base metals that being

Arc Welding or SMAW Generally known as stick or arc welding. Arc welding is the most basic of all welding types‚ is easy to master in a home welding situation. Stick welding can be used for manufacturing‚ construction and repairs‚ very much well suited for heavy metal size 4 millimetres upwards. Thinner sheet metals and alloys are usually more suited to the mig welding types. STEPS: 1. Gather your materials. You should have a welding machine‚ electrode holder with lead‚ ground clamp with lead‚

SUMMER INTERNSHIP REPORT FINITE ELEMENT TRANSIENT THERMAL ANALYSIS OF LASER WELDING PROCESS ABSTRACT In this project‚ Laser welding process has successfully been used for joining of two stainless steel plates. The sizes of the metal plates are 50mmX40mmX2mm each. The distribution of the temperature field in laser welding using stainless steel sheets were simulated by ANSYS. The thermal properties which have been used for thermal simulation are assumed to be varying with temperature

previous 50 years‚ welding has become more productive‚ automated‚ and safer. Generally‚ the welding norm was resistance based and performed with big machinery. The aerospace industry spurred the innovation of new ways to weld thin metal. At this point in history‚ all welding systems had good and bad aspects; the choice should be made with a balance between the different capabilities of the systems‚ including its power requirements and limitations. Manufacturers used this welding technology to hold
