Unit 003: Principles of welding Lesson 1 Handout 1 – Heat sources required for fusion welding The following basic notes have been produced for learners and tutors and if required could be extend. Objectives 3.1.1(a)(b)(c)(i)(ii)(d)(e)(i)(ii)(iii)(iv)(v) Introduction To make a fused joint the heat source must be capable of creating localized fusion in a controlled manner. Basic requirements for the production of a fully fused joint: Temperature should be `significantly above

There are lots job aids such like jigs‚ and pipe holders available to help welders do their job and minimize the risk of injury. Special chairs and creepers are available to provide support while performing welding tasks so that bad posture is avoided. There are many causes of injury in the welding field. Common causes of injury are repetitive gripping‚ twisting‚ repetitive reaching‚ and fatigue. Many injuries are developed when there is a mismatch between the capabilities of the worker and the demands

What is MIG Welding? Metal Inert Gas (MIG) welding‚ also sometimes called Gas Metal Arc Welding (GMAW) is a process that was developed in the 1940s for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is continuously passed through a welding gun. A flow of an inert gas‚ originally argon‚ is also passed through the welding gun at the same

A lot of skills today are looked over‚ and undermined. One of those skills is welding. Welding is more than just a blue collar job‚ and more than just sparks flying in the air. It is art. The art of joining metals and binding metals together‚ and requires more skill than the average person will ever know. Welding started in 1000 B.C. The history of welding begins with the discovery of shaping metals together from Copper‚ Bronze‚ Silver‚ Gold‚ and Iron‚ than so leading into steel. The first things

Welding Dangers Annotated Bibliography "Warning: Welding May Be Hazardous to Your Health." Warning: Welding May Be Hazardous to Your Health. N.p.‚ n.d. Web. 12 Feb. 2013. This article explains a little about welding fumes and how they are dangerous to people’s health. There are short term and long term respiratory effects from welding gases and fumes. Some of the gases that are inhaled can cause diseases such as ones close to Parkinson’s disease. To be protected from these fumes‚ the work area

A Definition of Welding Welding is a joining process that produces a local coalescence of materials by heating‚ by applying pressure‚ or both. In essence‚ the welding process fuses the surfaces of two distinct elements to form a single unit. It encompasses a broad range of joining techniques that include fusion welding‚ solid state welding‚ weldbonding‚ diffusion welding‚ brazing‚ and soldering. The Scope and Impact of Welding Welding dates back to the earliest days of metalworking‚ and continues

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

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

"Welding With Children" Language Analysis "He just stared at me‚ and i saw that he had no idea of what late was. Glendine‚ his mama‚ probably lets him fall asleep in front of the set every night. I pictured him crumpled up on that smelly shag rug she keeps in front of the TV to catch the spills and crumbs" (2). Within the passage it mentions that the child had no idea what late was. This indicates that his life is easy because he can fall asleep whenever he gets tired without a problem like he
