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

first hit Headnote PROTECT YOURSELF‚ FELLOW WORKERS AND VEHICLES DURING THE WELDING PROCESS As vehicle construction becomes more complex‚ the methods by which they’re held together also changes. Originally‚ many bolts and other compression fasteners were used. Now. most vehicles are put together by one of several welding processes‚ ranging from resistance spot welding to gas metal arc (GMAW) or MIG (metal inert gas) welding to spray brazing. To understand what makes acceptable welds‚ think of this:

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

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

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

UNDERWATER WELDING INTRODUCTION The fact that electric arc could operate was known for over a 100 years. The first ever underwater welding was carried out by British Admiralty – Dockyard for sealing leaking ship rivets below the water line. Underwater welding is an important tool for underwater fabrication works. In 1946‚ special waterproof electrodes were developed in Holland by ‘Van der Willingen’. In recent years the number of offshore structures including oil drilling rigs‚ pipelines‚ platforms

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

For the assessment of risk In order to work safely in a welding environment‚ it is necessary to be able to identify hazards and assess risks. To do that‚ one needs information‚ education‚ training and experience in the appropriate field of work. Legislation Employers have a duty to provide information‚ instruction‚ training and supervision to ensure health and safety at work. Employees have a duty to take care of their own health and safety and those of others‚ and must not intentionally or recklessly
