Welding

Welding all started centuries ago, yet many people still wonder what welding is all about. This quick snapshot will walk you through everything you need to know about the history of welding.

What is Welding?

Welding is the process of joining or melting two or more pieces of metal together. This process is also used for plastic, but the term "welding" often refers specifically to the use of metal. The process of welding creates strength and reinforcement for structures, ships, and modern machinery.

Welding's Ancient Roots

The practice of welding dates back to the Bronze Age, the era in human history when people began to use metal. People living during this time created small gold boxes using pressure welding on lap joints. As welding techniques became more refined in the Iron Age, this gave people the opportunity to build things using iron. During this time, Ancient Egyptians and other cultures used the skill for welding tools, among other necessities. While useful, this trade was limited by the tools used to perform the welding function.

Advancements in Welding

The 19th century saw great advancements in welding and its capabilities for modern applications. In 1800, Englishman Sir Humphry Davy introduced the arc to welding, a form made between two carbon electrodes using a battery. In 1836, Edmund Davy discovered acetylene, a gas capable of producing the hottest flame. This discovery led to a rise in popularity for gas cutting in 1850. While there were other notable welding innovations, the next major advancements came in the 20th century.

The Creation of Modern Welding

The 20th century saw many exciting advancements in the welding field. These advancements were, in large part, due to electrical power companies figuring out how to generate and distribute power. This accomplishment motivated scientists to find a way to use electrical power for welding. In 1920, General Electric's P.O. Nobel invented automatic welding thanks to his use of a bare wire electrode guided by a direct electrical current using arc voltage. From here, further research led to the discovery of various types of electrodes as well as alternate forms of gas welding and resistance welding. Work to refine welding techniques continued into the 1950s and 60s. In 1954, the Dualshield process gave welders a more efficient, portable option by using an external supply of shielding gas. This process was later abandoned for Innershield welding, which left the shielding gas behind and eliminated the need for welders to lug heavy containers around the job site. This improved process also made it possible for welders to work in outdoor conditions without having to worry about the wind blowing the shielding gas away and contaminating the weld. Since then, welding processes have become modernized, leading to the use of friction welding and laser welding. Welding techniques are sure to evolve as technologies advance. Scientists and inventors continue to look for more precise, safe, and environmentally friendly ways to build the products and infrastructure needed. The future for welding is bright. If you're looking for an opportunity to move the world forward, welding could be a great fit for you. We offer welding training at our Visalia and Fresno campuses.

Only about 5.8 percent of working welders are females, according to the American Welding Society. Companies are doing more outreach to women to help replace the welders who are approaching retirement. Welding is a career that can offer many benefits, but there are still a few misconceptions about women doing this type of work.

Myth 1: Companies Don’t Want to Hire a Female Welder

Metal fabricating companies are desperate to find good welders to replace the workforce that is rapidly retiring now. Both women and men are great candidates for these positions. Anyone can have a promising career in welding, as long as they get the proper training. Having additional skills, such as blueprint reading, will help you be a more valuable employee for prospective employers. Keep in mind that there may not always be welding jobs available in your area, and you may have to move to a more industrial city to find the job you want.

Myth 2: Male Co-Workers Don’t Respect Female Workers

Although male welders may have resented women coming into the field in the past, the younger generation is less apt to hold on to these gender differences in the workplace. They may have worked alongside women in the military or in other fields of work. They respect anyone who does good work and can work well as part of a team.

Myth 3: Welding Work is Hard, Dirty and Dangerous

Not all shop settings are alike. Some companies may not have state-of-the-art equipment or the safest environment. However, there are welding positions in forward-thinking companies with clean, climate-controlled environments and manageable materials. Female and male welders can benefit from staying fit in order to manipulate the heavy materials. They should also take safety classes to ensure that they can protect themselves and others in the work environment.

Myth 4: There’s No Room For Professional Growth in Welding

Many welders become supervisors or consultants. They work on projects that involve welding processes for construction or manufacturing of products. In addition, welding offers the opportunity of starting your own business, which can bring increased financial benefits. Women in welding is still a relatively new concept, but it is fast becoming the norm as more companies look for reliable people who can perform the highly technical work that welders do every day.

The commercial use of metals in the construction of equipment, buildings, ships and airplanes has created terrific employment opportunities. Welders can earn good salaries because of their skills. Although welders can earn a lot of money, the job can be hazardous due to high temperatures, materials and work environments. For those on an arc welding path, always put safety first. Here are some welding safety tips to keep in mind.

Electricity

Arc and other forms of welding use high voltage electrical equipment. The power can range from 20 to 100 volts. Death can result from exposure to less than 50 volts under certain conditions. It’s imperative that you understand and respect electricity. Never work in a wet or damp space. These include puddles, ground water or even where someone spills a coffee. Never handle electrified materials without safety gloves. If you are holding an electrified tool or material and touch another conductor, this can complete an electrical circuit right through your body.

Fire

The heat of a welding arc can hit 10,000 degrees. Be certain that you are not working near any combustible materials. Keep in mind that the arc itself does not have to touch other materials to start a fire. The sheer heat can start a blaze. Also, arc spatter is like shooting off a Roman candle. Work at least 35 feet away from flammable materials.

Safety Equipment

Always wear a complete outfit of safety equipment that includes rated clothing, gloves, face shield, safety glasses, and hearing protection. In commercial settings, you are not only protecting yourself from your own work, but also from those around you. Here are some of the common injuries caused by poor safety gear.

• Eye protection: Arc rays can cause what welders call “arc flash” that damages your eyesight. It can occur from other welders working to your side or even behind you. Also, small metal shards can become embedded in your eyes.
• Rated Clothing: High UV radiation produced by arc rays can cause intense skin burns. Welding spatter can burn through inadequate gear. Cover up.
• Ear Plugs: The high decibels from welding and metal gauging can damage your hearing.
• Helmets: Accidents such as falling materials can occur in industrial setting. Protect your head.

A post at Laboratory Network outlines how material scientists in Argonne, IL’s Argonne National Laboratory have developed a way to weld components made of high-temperature superconductors. The bond that results from this welding technique is strong enough to preserve uniform electrical flow across the joints and can be used for current leads, fault current limiters, energy storage devices, high-energy-density motors, and high-current wire or cable. Discovered in the 1980s, superconductors are known for losing electrical resistance when cooled with liquid nitrogen. However, superconductors do hold the potential for generating more efficient magnetic fields and transmitting electricity without losing resistance. Thus far researchers have been unable to grow large high-performance superconducting structures that are able to uniformly carry current, and they have found it difficult to join smaller sections together without interfering with electrical flow. The hope by researchers is that a new welding process may overcome this limitation. The new welding process will bond pieces of yttrium-doped barium-cooper-oxide (YBCO) using layers of thulium-doped barium-copper-oxide (TmBCO). The melting point of TmBCO is about 20 degrees Celsius cooler than YBCO. The materials are then heated to a temperature about mid-way between the two melting points. The YBCO “seeds” the liquefied TmBCO, while the joint cools, which provides a template at the TmBCO interface as it cools. This leads to a weld that preserves the YBCO crystal structure to a mechanically-strong weld that carries high current. While superconductors are materials that lose resistance to electrical current at reduced temperatures, the first of those identified were made of metals that became superconductive when they were brought near absolute zero (-270 degrees Celsius). The high-temperature superconductors found in the ‘80s lost its resistance at temperatures that allow the use of refrigerants such as liquid nitrogen. YCBO, on the other hand, becomes superconductive at -181 degrees Celsius. If you are interested in more information on this topic, you should read the original article by clicking here.
