Welding at ITCL

What is Welding?

Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal.

Overview

Welding is an essential component of many industries such as the automotive industry, the construction industry, the aviation industry, and more. Without this form of metal work, so many things, including many buildings, gates, and fences, small kitchen appliances, vehicles – and even space travel – would not exist.

Frequently Asked Questions

What is welding in short answer?

Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood. The completed welded joint may be referred to as a weldment.

Why is welding used?

The basic purpose of welding is to join two elements together with a firm connection. Welders typically work with metal or thermoplastic and use durable filler material to bind them together. Welding is used to create many modern constructions in our world, such as skyscrapers, cars, ships and airplanes.

What is welding class 8?

Welding is a fabrication process that lets you join materials like metals by using heat at high temperatures. Welding uses high temperature to join the materials, whereas soldering and brazing do not allow the base metal to melt. After cooling, the base metal and the filler metal get attached.

What is welding and fabrication?

Simply put, welding joins together two pieces of metal, glass, or thermoplastics with similar melting points and compositions using fusion. Fabrication is the evolutionary process of creating a metal product, from layout and design to formation and finishing.

What is gas welding?

Acetylene is the only fuel gas suitable for gas welding because of its favourable flame characteristics of both high temperature and high propagation rates. Other fuel gases, such as propane, propylene or natural gas, produce insufficient heat input for welding but are used for cutting, torch brazing and soldering.

What is structural welding?

Structural welding involves creating a variety of welds with different component materials to create, fabricate, and erect welded structures. Structural welding has its own set of codes, blueprints, and types of weld joints.

What is oxygen welding?

Oxyacetylene welding, commonly referred to as gas welding, is a process which relies on combustion of oxygen and acetylene. When mixed together in correct proportions within a hand-held torch or blowpipe, a relatively hot flame is produced with a temperature of about 3,200 deg.

Why do welders drink milk?

So why do welders drink milk? The fumes released when welding, cutting, or brazing galvanized steel can cause a condition known as Metal Fume Fever. The thought is that milk helps the body rid of toxins encountered when welding galvanized steel and thus prevents them from getting sick.

Why acetylene is used in gas welding?

Acetylene produces a flame temperature of ~3100 degree Celsius along with oxygen. This high flame temperature makes acetylene a suitable choice for gas welding steel. 2. Welding: When burned in oxygen, acetylene produces a reducing zone, which easily cleans the metal surface.

Is welding difficult?

So is welding hard? For most people, welding is moderately to very difficult to learn how to do, as it’s a hands-on skill that requires more than just reading. Furthermore, welding is very difficult to actually do for most people, because it takes years and years of practice, on top of learning how to do it.

Does welding shorten your life?

A beam falling on a welder, a fire or a metal fume fever can all contribute to a shortened life. Generally, large beams falling are rare, but they tend to happen more on large ironworking projects for buildings and skyscrapers.

Is welding a good career?

Welding is an excellent career, and welders commonly praise their profession and extol the many benefits they get from welding as a career. Overall, if you can handle extreme conditions, long hours, and smoke and fire regularly, a career in welding can be rewarding.

Can you teach yourself to weld?

Most people can learn the fundamentals of welding on their own to make basic fabrications and do common repair work by researching content from reliable sources and a lot of practice. However, if you have professional intentions, you cannot reach a high skill level fast enough without the guidance of experts.

Is welding a safe career?

Many businesses are looking for skilled welders and you can consider it one of the more secure jobs available. Striving towards safety awards and bettering your skills can also be high on your list. Welding may not be the choice for everyone, but for those interested, it can be a lucrative, rewarding career to have.

How long does it take to become a welder?

A welding program may last just a few weeks or take up to six months to complete. A school for welding will cover welding theory and welding basics to arm students with the skills they need to start work upon completion.
