Are you planning to start a new welding company or workshop? If so, you must invest in a good welder for the job. Operators often use welders to complete various projects, and in some situations, you can use them for the same tasks, but the output will be different. Today, we’re going to take you through different types of welding machines you can buy and use in your project:
1. Laser Welders
Welders use These powerful machines to join thermoplastics and metal parts using a fiber laser beam. Through laser welding services[1] , you can handle projects like butt welding, seal welding, stitching, and welding precision parts/thin-walled materials. You can use these welders in the automobile sector for part and body welding.
2. Plasma Arc Welders
A plasma arc welder is a precision machine used in the aerospace industry, where the required thickness of metals is 0.0015 inches. This machine is often used in air seals or engine blades. The shielding gas in this welder consists of around 5% hydrogen and argon. Operators can also use helium, but since this gas is hotter, it can minimize the nozzle’s current rating.
3. Submerged Arc Welders
These welders create an electric arc between a continuously-fed electrode and the work piece. Its reusable powder flux substitutes shielding gas, resulting in quality welds. They can be automatic or semi-automatic and require the operator to have minimal experience. This makes these machines more suitable for steel/nickel alloys, stainless steel, and steel. However, because of the machines’ automated configurations, they are not portable.
4. Stick Welders
Stick welders use electric currents between the filler rod (stick) and base metal to generate enough heat for welding. This rod is often covered with a flux, which helps to prevent contamination and oxidation by producing CO2 during the process. They operate by both DC and AC currents, making them suitable for cast iron, inox steel, and steel. Mostly, you will see operators using them in the following:
- Maintenance
- Steel erection
- Repair of farm equipment
- Construction
- Pipeline welding
5. TIG Welders
TIG (tungsten inert gas) welder, sometimes called GTAW (gas tungsten arc welding), guarantees specialized welding, which reduces fumes, splatter, and sparks for a more precise and cleaner finish. TIG welders can handle different metals, including copper, aluminum, magnesium, brass, nickel alloys, gold, and stainless steel. Although not widely used, you can use tungsten inert gas welding[2] to repair damaged parts, making them suitable for specialized objects and pieces.
6. CO2 Gas-Shielded Welders
These welders have a more advanced fusion system, which uses CO2 as the protective gas to protect the molten pool and isolate air. According to experts at Micro Weld[3] , they are straightforward to use and more suitable for omnidirectional and automatic welding. In addition, they are ideal for indoor settings, but it will be important for operators to pay more attention to gas protection and their working environment.
7. Spot Welders
These resistance welding machines assemble weldments into a lap joint and press them between cylindrical electrodes. They often use resistance heat to melt base metals and form solder joints. Because of that, operators use them to repair inlaid parts/seams, fix holes in silver/gold jewelry, and spot blisters in materials.
8. FCAW Welders
FCAW (flux-cored arc welding) machines have a continuous supply of flux. Therefore, they don’t need a gas supply to work. Operators prefer them when welding a thicker surface, so it won’t be helpful when dealing with thin materials.
The bottom line is that you will find different kinds of welders in the market, all with advantages and disadvantages. However, when choosing a suitable machine for your project, consider factors like power requirements, welding position, budget, materials’ thickness, and types of materials to weld.
