Welding is the process of joining materials, traditionally metals, and is an ancient craft. Welders work in heavy and light industry, construction, and as freelancers. Training can be obtained through vocational schools or on-the-job apprenticeships. Welders must be strong, skilled, and careful, and may specialize in different types of welding. A welder is someone who […]
An inverter welder uses solid-state rectifiers and switches to convert AC input power to DC output power, controlled by computer software. It is smaller, lighter, and more energy-efficient than traditional welding power supplies, with a higher frequency output current for consistent welding. It can power all welding processes and is popular in maintenance, repair, and […]
A seam welder uses spot welding to create continuous welds with no gaps. Welding wheels made of copper alloy are used as electrodes, and the technique varies depending on the materials and thickness being welded. Advantages include high speed and minimal fume generation. A seam welder is a device that uses a variation of the […]
Buying a used TIG welding machine can save costs, but buyers must ensure it has all required functions. TIG welding is suitable for various metals and requires consideration of job requirements and available features. Additional features, such as push-button control and pulse mode, can improve efficiency. Anyone who is an experienced welder and metal fabricator […]
A spot welder uses an electric current to melt two pieces of metal together. It can be made with a power source, transformer, and electrodes, but commercial ones are more complex. It can join thin pieces of metal and thicker ones with protrusions. The correct width and duration are necessary for a strong bond. A […]
An arc welder uses electric current to melt steel and join pieces together with a welding rod. The rod is covered in flux to protect the weld from contaminants. The traditional arc welder is being replaced by the MIG welder, which uses a coil of wire and a shielding gas. The TIG welder uses a […]
Stainless steel welders use MIG, TIG, or shielded metal arc welding to create high-performance equipment. They must wear protective gear due to toxic fumes and high heat, and must understand different types of steel to make strong welds. Proper preparation and selection of materials is crucial. A stainless steel welder connects stainless steel parts through […]
Becoming a structural welder requires meeting specific fitness requirements, passing certification exams, and proficiency in various types of welding and cutting operations. Physical agility tests may also be required, including lifting and carrying weights, bending, crawling, and remaining in uncomfortable positions for extended periods. Welders must also have good hand-eye coordination and depth perception. To […]
A soldering iron is used in welding to join metal or plastic. It melts a metal alloy called solder, which fuses with the material being joined. Flux prevents impurities and oxidation. The iron needs cleaning and a new layer of solder applied to prevent oxidation. Care is needed when using it due to the hot […]
Gas welding is a skilled craft used to cut and join metal, taught through specialized trade programs. There are three types of equipment, each using different gases, with TIG welding being the best option for aesthetics. The type of gas welder used depends on the thickness of materials. A gas welder uses compressed gas and […]
