Low voltage arc welding can cause several issues. A voltage drop affects the welding arc and lowers weld quality. It can lead to cold lap, where the filler metal fails to fuse with the base material. Maintaining proper voltage and high amperage is crucial for achieving strong weld penetration and avoiding welding defects. Advanced technology … Read more

Tubular Arc Welding Electrodes include flux cored and metal cored types. The Material Safety Data Sheet (MSDS) offers important safety information and handling procedures for these welding consumables. It helps ensure compliance with OSHA’s Hazard Communication standards, focusing on safety during use and emergency responses. Proper ventilation is also crucial to minimize fume inhalation. The … Read more

To master horizontal arc welding, use the E6013 electrode at a slight upward angle. Set the welder to create a tight arc. Control the puddle by moving forward and upwards slightly. Practice backhand or drag techniques for stability. Remember, the angle of travel significantly impacts your results. Use these essential tips to improve your skills. … Read more

Hot cracking in submerged arc welding happens when large weld pools cool too quickly. This issue often occurs along the centerline of the weld. High welding speeds can worsen the problem by creating thermal stress, which leads to cracks as the metal solidifies. Proper control of welding speed can help prevent this defect. Preventing hot … Read more

The average hourly wage for an arc welder is $21. Top earners receive $31 per hour. Those in the 75th percentile earn $25, while the 25th percentile makes about $16. Salaries for arc welders can differ based on experience and region. Skill level significantly impacts earnings as well. Arc welders with certifications or advanced training … Read more

Submerged arc welding is a method that forms an arc between a wire electrode and a welded workpiece. The grounded connection completes the electrical circuit. The resistance to current flow melts the wire and the workpiece, producing a strong weld. This process is known for its efficiency and high-quality results. The primary benefit of HWSAW … Read more

The history of arc spray, or spray welding, started in the late 1800s. In 1911, M.U. Schoop patented the flame spraying process. This thermal spray technique melts coating materials to enhance worn metal parts. By the 1950s, self-fluxing alloy powders gained popularity, expanding industrial applications in surface coating. In the 1980s, innovations in materials and … Read more

Plasma arc welding was invented by Robert M. Gage in 1953 and received a patent in 1957. This technique allows for precision cutting and welding of thin and thick metals. It also enables spray coating for hardening metals, making it a significant advancement in welding technology. The process of Plasma Arc Welding involves creating a … Read more

Carbon arc welding started in the late 1890s. C.L. Coffin from Detroit received the first U.S. patent for using a metal electrode in arc welding in 1890. In the early 1900s, Strohmenger introduced the coated metal electrode in Great Britain, which improved the welding process significantly. By the late 19th century, carbon arc welding gained … Read more
