The ancient Greek historian Herodotus states in The Histories of the 5th century BC that Glaucus of Chios "was the man who single-handedly invented iron-welding."[1] Welding was used in the construction of the iron pillar in Delhi‚ India‚ erected about 310 AD and weighing 5.4 metric tons.[2] The Middle Ages brought advances in forge welding‚ in which blacksmiths

INTRODUCTION TO WELDING & FUSION WELDING PROCESS Dr. Tasnim Firdaus Ariff Welding Fundamentals Overview of Welding Technology 2. The Weld Joint 3. Features of a Fusion Welded Joint 1. 2 Joining and Assembly Distinguished Joining - welding‚ brazing‚ soldering‚ and adhesive bonding These processes form a permanent joint between parts Assembly - mechanical methods (usually) of fastening parts together Some of these methods allow for easy disassembly‚ while others do not 3 Welding Joining process

Being a welder is a great occupation What is welding‚ and how does it work? Not many people know what welding is or how it works. According to Mary Bonk“welding is the process of heating and melting metal parts to join them together” (Bonk‚3). A welding machine uses electricity to melt the electrode‚ fusing one piece of metal to another. The welding machine uses a ground that connects to the surface that allows the welder to create a flowing currant passing through the electrode and

TIG welding T ungsten inert gas (TIG) welding is a high quality low deposition rate welding process. It uses an arc struck between a nonconsumable tungsten electrode and the work to fuse the base material and thereby form a welded joint. The TIG welding process may be used on thin sheet material without the addition of a filler metal (autogenous TIG welding). Alternatively‚ when working on thicker sheet or when joining dissimilar materials‚ a separate wire filler metal is added

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

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

term‚ which covers processes such as welding‚ brazing‚ soldering‚ adhesive bonding‚ and mechanical joining. These processes are an important and necessary aspect of manufacturing operations. This paper deals with one topic in particular ‘Welding’. Welding is a process for joining similar metals. Welding joins metals by melting and fusing the base metals being joined and the filler metal applied. Welding employs pinpointed‚ localized heat input. Most welding involves ferrous-based metals such as

Evolution of Welding Welding? Yes‚ welding have you ever wonder how it has been revolutionised throughout the years. The man who created welding was Edmund Davy with the help of Sir. Humphry Davy in the late 1800’s. As the years go on the technique of weld was further advanced. With the evolution of welding many of the ways created back in the start have been adjusted and also have been modified for the use for the everyday welder. Welding is a very difficult and hard working job that can take a

. SUMMARY OF PROPOSAL 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
