Welding is a process used to join metal parts by producing a coalescence, called a weld, at a joint. Advances in welding technology have opened the way for innovative designs in structures and machinery. Of modern welding processes, the greatest number fall under the general classifications of arc welding, gas welding and cutting, resistance welding, and brazing.
Tungsten Inert Gas (TIG) welding is one of the arc welding methods. This method is suitable for many kinds of metals, but especially for welding of stainless steels, aluminum and magnesium.
In stainless steel industry, TIG welding has an important role on joining thin sheets, tubes and pipes. Depending on this important role, the mechanical behaviours of TIG welded joints and criteria affecting these behaviours are the main cared subjects in industry to obtain products with less failure and use them for longer service times. Mechanical behaviours of TIG welded joints in stainless steels are also the main subject of the senior project which will be submitted at the end of this year.
The objective of this proposal is to give information on the plan of the project about the mechanical behaviours of TIG welded joints in stainless steels, regarding on the research facilities, equipments, materials and the methods that will be followed and used during the preparation of this project.
1. TIG Welding
TIG welding, which was developed in late 1920's and perfected in early 1940's, is a commonly used high quality welding process and has become a popular choice of welding processes when high quality, precision welding is required and nearly all metals can be welded by using this process. The main application areas of TIG welding can be mentioned as naval industry, i...

5. CONCLUSION
Mechanical behaviours of TIG welded joints in metals show differences depending on the changes in parameters which are used during the welding process. Effects of these changes in welding parameters on stainless steels' mechanical behaviours will be examined and discussed as the subject of this senior project.

scientific experiments (Go welding: history of welding 1). Conventional welding is most easily explained as arc welding processes. Some arc welding processes are TIG welding, Stick Welding(SMAW), and MIG welding. TIG stands for Tungsten Inert Gas welding this means that using tungsten as a electrode and an inert gas, which is usually argon, the weld is produced by creating an arc between the piece being welded and the tungsten electrode. SMAW or stick welding utilizes a stick electrode held in a clamp surrounded by a powdered substance to weld. Mig welding uses a machine that holds a wire feeder within it, the wire feeder feeds the wire electrode through a tube to a gun that slowly sends out the wire as well as a steady flow of inert gas. These and other processes classified as conventional welding processes are the best processes for welding jobs because they are more cost effective, more...
For the other material ASTM A216 Gr WCB same pressure of 16 Mpa is applied and the stress developed is approximately as similar to the connecting rod made with material of cast iron. Figure no. 9 indicates the maximum and minimum stress developed in connecting rod at small & big end. The equivalent stress maximum and minimum values are 71.347 MPa and 4.4955e-5 MPa respectively.
Tomorrows Welders Thomas Jefferson said, “I find that the harder I work, the less I call it work”. I have often found myself in situations where I needed to fix something but could not because it is metal. I believe this might be why I began to show interest in welding. There is great satisfaction in being able to create or fix a metal object on your own.
Welders can use hand held welders or even robotic welders to produce welds. Both equally requiring a incredible amount of knowledge. They can also fill holes, produce structures and build custom parts for automotive race shops. Welders often work fulltime on shipyards, oil rigs, and pipelines or anywhere else where a specific job is needed. Welders are often required to interpret blueprints or sketches and weld accordingly to fulfill job duties. Arc welding is the most common type of welding today and is what most welders use. (bls) There are over 100 different welding processes that a welder can learn how to use however, Stick, Tig and Mig are the 3 most common used in the industry. These are used most to maintain equipment
Welding can be traced back to the ancient times. One of the earliest methods of welding is bronze age. when ancient people back then had small gold circular were made by pressured welding lap joined together. Then in the Iron Age the Egyptians and people in the eastern area learned to weld pieces of iron together. In the middle age blacksmithing was developed. Blacksmithing is when you weld a piece of metal and hammering it but it was in the 19 century that welding was invented as they know it today.
The first step in the heat treatment of AISI D2 tool steel was hardening. The purpose of hardening was to harden steel to increase the wear resistance, cutting ability. Hardening of AISI D2 tool steel was done at a temperature of 1020°C [6] for 1 Hour. Harden AISI D2 tool steel followed air cooling which provides great benefit of minimizing distortion and dimensional changes [6]
Skills of welding students welding program learn the art of heating and shaping metal, required classes may include advanced mathematics. To become a certified welder you are required for two year educational high school or college. Travel opportunities for welders you prefer the open or even the open ocean to a cramped office, life style of the ‘’road warrior’ ’welder could lead to an exciting career once you’ve completed a welding program, these travel bound welders are used to going across the country in order to work on huge projects. The advantage of becoming a welder you have plenty of travel opportunities your afford to work on land/or ocean.

This report looks at how heat tempering, solution annealing and cold work hardening, can change the properties of stainless steel. There are three main grades of stainless steel, these grades are ferritic, Austenitic and Martensitic. These grades have different ways of hardening. There are other grades of Stainless Steels that don’t fit in with the other grades, these are known as special stainless steels and are prescription hardenable.

Welding is an art, science, and high paying career all in one. Welding is the most effective way to join two pieces of metal, it is the only way to join them so they act as one. Numerous things in our daily lives has been welded from coffeepots to skyscrapers. Welding can be done almost anywhere outdoors, indoors, underwater, and even space (“Welding Basics”). It is practically

In this paper we will explore on the brief manufacturing process of steel containers and some vital issues relating to the production process.
There is different types of rods and different types of ways to weld. You need a lot of training for it. There are many schools and colleges you can go to receive welding education. The most common welding processes are Gas Metal Arc Welding, Flux Core Arc Welding, Gas Tungsten Arc Welding and Shielded Metal Arc Welding. The easiest of these is the Gas Metal Arc Welding. Welding options are stick, flux core, tig, and mig. The pipeline tig and stick welds a lot more than the other .The pipeline use many types of techniques but, the most common on the pipeline is downhill root pass and the up hill pass. The median annual wage of welders, cutters, solderers, and brazers is
Project planning falls in the Planning Process Group which consists of those processes to establish the projects total scope, define the projects objectives, and courses of action to achieve those objectives. During the planning process, all the documents that are needed to carry the project through the project lifecycle will be developed such as the project management plan. Project management requires repeated feedback loops as additional information becomes available and is better understood. The planning process delineates the strategy, tactics, and path to successfully complete the project. With that, the planning of a project must walk through all the those processes from executing, monitoring and controlling through the closing process.
