ARC Welding

Arc welding mild steel to cast iron uses mild steel electrodes. This welding process can produce high-carbon steel known as Martensite. Martensite is hard but weak and difficult to machine. Always inspect all parts for pressure breaks or damage before welding. This ensures a strong bond and prevents weaknesses in the weld. Next, preheating the … Read more

Pulse arc welding is perfect for sterling silver because it creates stable, crack-free welds. It uses solid sterling wire, which ensures a perfect color match. Many jewelers choose the Orion 150S for torchless welding. Adding 5% platinum alloy to the sterling wire improves the welding process and enhances durability. Before beginning, it is essential to … Read more

Shielded metal arc welding (SMAW), also known as stick welding, is a manual welding technique. It employs a consumable electrode covered in flux, which helps create a strong weld. This process generates a protective gas shield, enhancing the weld quality. SMAW is popular in construction and repair due to its versatility and efficiency. Another critical … Read more

Arc welding is a method that uses an electric arc to produce heat and join metals. Key processes include Stick Welding and Flux Cored Arc Welding (FCAW). This technique utilizes a welding torch and electrodes. It may also involve shielding gas to keep the weld area safe from contamination during coalescence. Additionally, “amperage” measures the … Read more

Arc length, or arc gap, is the distance between the electrode tip and the workpiece in welding. It affects weld quality. Key factors include arc stability, weld current, and workpiece alignment. Keeping the right arc length is essential for effective welding and achieving strong, consistent welds. The importance of arc length extends to the overall … Read more

The Sub Arc Welding Test evaluates skills in submerged arc welding (SAW). It requires a minimum 15-inch weld with a stop and restart. Key attributes include welding speed, arc voltage, and penetration depth. SAW is efficient but works well only in flat or horizontal positions. Understanding these factors is crucial for success. Quality issues can … Read more

To pass an arc welding test, focus on technique and practice. Use 7018 electrodes for strong welds. Control the puddle and ensure proper bead formation. Familiarize yourself with the 3G and 6G welding tests. Review tips from credible sources, and keep your work area free of defects like slag or porosity. The video emphasizes the … Read more

Accredited Testing Facilities (ATFs) and CRAW Approved Testing Centers (ATCs) offer vital services for arc welding certification. They perform destructive and nondestructive testing to ensure welds comply with AWS and ASME codes. OXARC Welding Inspection and ATS enhance the process through expert consultation and advanced testing capabilities. Certification from arc welding testing facilities ensures compliance … Read more

Gas metal arc welding (GMAW) is a key metal joining process widely used in manufacturing. It uses a continuously fed consumable wire electrode. An electrical arc forms between the electrode and the workpiece, melting the metal to create strong welds. GMAW is known for its speed and versatility in various applications. Guidelines for effective GMAW … Read more
