Welding technology dates back to 1750 when the Industrial Revolution began. A procedure known as forge welding was used during the time. In forge welding, the ends of the materials were heated until they were hot enough to be pounded together.
The welding industry is changing at a faster rate than it has ever before. Welding has become more accurate, efficient, and cost-effective as a result of current developments. Here’s how new technology is transforming the welding equipment and industry.
1. Automated Welding
The welding process has now entered the age of automation, thanks to extraordinary technological advancements. Automation has also allowed the sector to keep up with the ever-increasing demand for welding goods from other industries. Automation not only provides for speedier production but also allows for a more precise welding process, which is critical in the transportation, aerospace, automotive, and marine industries.
Welding robots are also becoming more popular. These robots can execute the task faster, even though they demand significant investment. In addition, laborers are protected from potential welding-related injuries and dangers.
2. Reduced Welding Failures and Rework
When it comes to obtaining fewer weld failures, a greater first-time weld rate, filler metal selection, and consistent arc performance are critical. Industries can save time and money by reducing the amount of time and resources spent on weld failure and rework. Remember that admitting the need for change is challenging since it necessitates a focused and well-organized effort.
Given the rapid advancements in fabrication and machining technologies, it’s critical to examine your manufacturing processes and assess whether advanced welding machines will help you boost your profits. Manufacturers now have unparalleled levels of control because of advancements in welding technology.
3. Laser Welding
High welding speed, reduced thermal distortion, and narrow weld seams are all advantages of laser welding. Light Amplification by Stimulated Emission of Radiation (laser) is an acronym for Light Amplification by Stimulated Emission of Radiation. As a result, laser welding is a non-contact method.
The laser acts as a focused energy source, allowing the material to heat up more quickly. Laser welding may be used to create three different types of welds. Conduction, conduction-penetration, and keyhole are the three types.
Laser welding is effective in high-alloy metals and can be performed outside. It does not require filler metals and is exceedingly exact, unlike other procedures. It’s used in the manufacture of medical equipment, electronics, and jewelry, among other things.

4. Stir welding with Friction
Friction stir welding is a Cambridge-developed technique. It operates by pressing into the materials’ junction and traversing along the welding route with a spinning tool. The materials are fused using frictional heat generated by the machine’s spinning shoulder. The softened material is also contained in the shoulder, which creates a solid phase weld during the process.
It is used to join components composed of aluminum and other alloys and, like laser welding, does not require filler materials. Friction stir welding produces a high-quality, solid weld when elements are adequately constrained.
This technology provides several advantages over other welding techniques. It delivers the output with minimal or no distortion, produces no fumes or radiation, and saves energy.
5. Arc Welding (Advanced)
Welding with an arc is a method of joining metals together. Electric current is used to create an electric arc between the materials and an electrode in this process. The filler metal put between the joints of the two components is melted with the help of heat. A metallurgical bond is formed as it cools and solidifies. Because the joint is made up of various metals, the weld may have the same strength as the component metals.
Non-ferrous metals are welded using this method. It is also commonly used in the production of spacecraft and bicycles. This procedure produces welds resistant to corrosion and cracking over long periods, making it ideal for critical welding activities like sealing spent nuclear fuel canisters.
6. Enhancements to Welding Safety
Safety should always come first! Fabricators will continue to take precautions to keep workers safe, even though this is not a new practice. Automated welding can be harmful if sufficient safety precautions are not accepted. The following are a few of the most common dangers:
● Gases and Fumes Exposure
● Burns, eye damage, wounds, and other physical hazards
● Explosions and Electric Shock
Interlocking perimeter guards, light safety curtains, laser scanners, sensors, pressure-sensitive safety mats, high-quality gear, auto doors, better smoke extraction systems, and more are all being used to increase the safety of automated welding.
7. Improved Waveform Technology and Welding Power Source
Welding power source technology has advanced in the last decade, allowing for higher speeds and quality, as well as increased throughput and consistency. These developments are beneficial to businesses suffering from a skilled labor shortage, as many are looking for ways to increase output while employing fewer people.
Machines are also easy to operate thanks to the power source technology, and they’re specifically built to assist welders of varied skill levels, saving money on training and time. Waveform technology has allowed us to weld applications that were previously impossible to weld with robotic welding.
8. Robotic welding
Robotic welding involves using programmed manipulators or robots for the entire welding process, from start to finish. These robots are outfitted with a three-dimensionally bending arm, part manipulation to fuse the two metals, and a welding gun and power source.
When comparing the utilization of robotic welding versus manual welding, robotic welding wins practically every competition. Welding robots can weld consistently every time, which is very useful for recurring and speedier welds.
Missed welds are the leading cause of weld inspection failures. Robotic welding eliminates this problem. Weld failures and contaminants are eliminated when robotic welding is used. Robots will reduce labor expenses and eliminate the need for more qualified welders.
Conclusion
There are numerous chances to increase production and save time and money by utilizing new and improved welding technologies. Technology improvements can assist you in overcoming important welding issues, allowing you to remain competitive in your niche industry.
