ARC Welding

There are several types of arc welding joints: Butt Joint, Corner Joint, Fillet Joint, Lap Joint, and Edge Joint. Each joint has specific applications. Common weld types include Groove Weld and Plug Weld. Choosing the correct joint design affects the strength and quality of the weld in various fabrication processes. Butt joints connect two pieces … Read more

Submerged arc welding (SAW) uses welding speeds of 20-59 inches per minute. Faster speeds decrease bead width and increase the risk of porosity. Slower speeds may lead to burn-through. The ideal travel speed and voltage (28-32 volts) improve weld quality and achieve high deposition rates, making SAW efficient and effective. In SAW, maintaining an appropriate … Read more

Submerged Arc Welding (SAW) is a welding technique that creates an electric arc between a continuously fed electrode and the workpiece. It operates under a protective layer of flux, preventing contamination. SAW improves productivity, ensures deep weld penetration, and produces minimal smoke. It is ideal for thick materials and is used in various industries. The … Read more

Sub arc welding (SAW) uses a continuous bare wire electrode to create an arc. Welding time is reduced with typical deposition rates of 15 to 20 lbs. per hour and travel speeds of 20-25 inches per minute. This method enhances productivity and quality, especially for thick materials ranging from 2 to 8 inches, while improving … Read more

Carbon Arc Welding (CAW) is a metal joining process that creates a strong bond through coalescence. It uses an electric arc between a non-consumable carbon electrode and the workpiece. This arc generates high temperatures, melting metals, especially copper. Always wear proper Personal Protective Equipment (PPE) for safety. This welding method is commonly used in various … Read more

Welding speed in arc welding shows how fast the welding arc moves across the weld joint. It is measured in inches per minute (IPM). For semiautomatic operations, beginners typically travel at 10 to 12 IPM, while experienced operators may reach 18 to 20 IPM. This speed impacts both weld quality and efficiency. Maintaining an appropriate … Read more

The optimal welding parameters for shielded metal arc welding are as follows: a welding current of 160 A, a groove angle of 60 degrees, an electrode diameter of 3.25 mm, a root gap of 3 mm, and a root face of 3 mm. These values help achieve strong and quality welds. Arc length, which is … Read more

Short arcs reduce electrode sticking but might lower penetration. Long arcs produce more spatter and can cause defects like undercuts and porosity due to high voltage. Finding the right arc length balances these issues. Choose short or long arcs based on your project’s needs to achieve strong, quality welds. Conversely, long arc welding involves a … Read more
