Slag inclusion in submerged arc welding looks like elongated lines on the weld. These defects come from the flux used during welding, especially in MMA and FCA processes. They can also happen in MIG welding. Radiographic inspection can identify these inclusions, revealing possible problems in weld quality. Quality issues from slag inclusion can compromise structural … Read more

Submerged arc welding uses a molten electrode and base metal to create a weld. After welding, a layer of slag forms as the weld cools. This slag must be removed for a clean result. Workers typically use chipping or grinding methods to take off the slag, ensuring optimal weld quality and appearance. One common method … Read more

Submerged arc welding (SAW) uses a large wire electrode fed under a flux layer. This creates clean, spatter-free welds. Key attributes include wire sizes (1/16” for thin metals, 5/64” for thicker), welding parameters, and consumable electrodes. AWS A5.17 covers electrode and flux specifications. A Welding Procedure Specification (WPS) describes required procedures. Electrodes in submerged arc … Read more

{Submerged arc welding (SAW) uses a continuously-fed wire electrode to form an arc with the workpiece. This process employs flux for gas shielding, preventing atmospheric contamination. During World War II, SAW was key in building the T-34 tank, improving its armor composition with enhanced quality, including the use of nickel rods.} SAW offers several advantages … Read more

Submerged arc welding (SAW) is a welding process created by the E O Paton Electric Welding Institute during World War II. It uses a continuously fed electrode and granulated flux to shield the molten weld pool. SAW was essential in constructing the T34 tank, though the quality of production varied across different units. The high … Read more

Submerged arc welding (SAW) is an industrial welding technique that uses an electric arc between a continuously-fed wire electrode and the base material. It offers high efficiency and precision. This makes it perfect for large-scale production in the automotive industry, especially at Toyota, where robots can automate the welding process for consistent results. Robotic automation … Read more

Submerged arc welding (SAW) is an automatic welding process. It uses flux to generate protective gases and slag. SAW achieves high deposition rates, making it suitable for butt and fillet welds. This method eliminates the need for shielding gas and provides excellent penetration with little cleanup required. Moreover, Submerged Arc Welding TWI minimizes spatter and … Read more

Submerged arc welding (SAW) is an efficient welding process created in 1935. It was widely used during World War II for steel manufacturing, enabling quick ship production. SAW produces clean, spatter-free welds by utilizing a flux blanket. This technique improved speed and accuracy in shipbuilding applications during that time. The significance of submerged arc welding … Read more

The “Symbols for Welding” (EW-342) program from the Hobart Institute of Welding Technology covers essential welding symbols. It follows the AWS A2.4 Standard and is in loose-leaf format (ISBN 9781936058242). It is available for purchase or rent, making it ideal for educational use in welding instruction. The guide breaks down essential elements such as the … Read more

Symptoms of burning eyes from arc welding include pain, bloodshot eyes, light sensitivity, watery eyes, blurred vision, and a feeling of something in the eye. These symptoms may start a few hours after exposure. If you experience severe pain or vision changes, seek medical attention immediately. Other causes of burning eyes during welding include smoke … Read more
