ARC Welding

Arc welding works by creating an electric arc between an electrode and the base metal. This arc generates heat and melts the base metal. If a filler wire is used, it also melts and forms a molten pool. As the molten metal cools, it solidifies and fuses the edges of the parent material, forming a … Read more

Shielded Metal Arc Welding (SMAW) is a manual welding process. It uses a flux-coated, consumable electrode to create an electric arc. This arc melts the electrode and base metal, which fuses them together. SMAW is popular for its simplicity and versatility in many applications, making it a common choice in fusion welding tasks. SMAW is … Read more

Electric arc welding reaches temperatures up to 10,000 degrees Fahrenheit. This high heat is effective for joining different metals. Each metal type has specific temperature needs for the best results. Knowing these temperatures ensures safe and efficient welding processes. Different types of electric arc welding processes, such as Shielded Metal Arc Welding (SMAW), Gas Metal … Read more

The temperature of a welding arc usually reaches about 10,000 degrees Fahrenheit. This heat level can change depending on the metals involved. In contrast, plasma torch welding can reach up to 50,000 degrees Fahrenheit. Therefore, arc welding is very hot but less intense than plasma torch methods. Techniques for controlling welding arc temperature vary. For … Read more

An arc strike is a welding defect. It happens when the electrode creates an arc outside the intended weld zone. This can form a metallurgical notch, which causes localized stress risers that may lead to cracks. Arc strikes can occur from accidental discharge, like scratching or tapping, or from the movement of the ground clamp. … Read more

Submerged arc welding (SAW) is a welding technique that takes place beneath granulated flux. This flux protects the weld from atmospheric contamination. Common flux components include manganese oxide, magnesium oxide, and silica. This method improves weld quality and reduces defects, making the process efficient and reliable. Essential equipment for submerged arc welding includes a welding … Read more

The main types of arc welding are: 1) Shielded Metal Arc Welding (Stick Welding), 2) Gas Metal Arc Welding (MIG/MAG), 3) Flux-Cored Arc Welding, 4) Gas Tungsten Arc Welding (TIG), 5) Plasma Arc Welding, 6) Carbon Arc Welding, 7) Submerged Arc Welding, and 8) Atomic Hydrogen Welding. SMAW, also known as stick welding, utilizes a … Read more

The temperature of a welding arc usually reaches about 10,000 degrees Fahrenheit. This heat effectively melts many metal types in the welding process. Compared to other methods, it is hot but cooler than plasma torch welding, which can rise above 50,000 degrees Fahrenheit. For Tungsten Inert Gas (TIG) welding, the arc temperatures can exceed 7,000 … Read more

Arc welding was invented in 1881 when Nikolai Benardos demonstrated it using a carbon electrode at the International Exposition of Electricity in Paris. He patented this invention in 1887 with Stanisław Olszewski. This innovation transformed the welding process and laid the groundwork for modern welding techniques. By 1900, the adoption of arc welding grew due … Read more

The four main types of arc welding are: Gas Metal Arc Welding (GMAW), which uses a continuous wire feed; Gas Tungsten Arc Welding (GTAW), known for its precision; Shielded Metal Arc Welding (SMAW), which uses a coated electrode; and Flux-Cored Arc Welding (FCAW), which utilizes a tubular wire for improved efficiency. These techniques utilize electric … Read more
