ARC Welding

The normal no-load voltage range in DC arc welding is 60 to 80 volts. This voltage is essential for starting and sustaining the electric arc. It helps create a consistent weld between the welding electrode and the workpiece, promoting efficient welding operations. A higher OCV allows for a more stable arc, making it easier to … Read more

Ensure your welder is properly installed and grounded. Always work in well-ventilated spaces to prevent fumes. Wear fire retardant clothing, gloves, and shoes for body protection. Use eye protection at all times. Lastly, conduct welding only in a designated firesafe area to reduce fire risks and ensure safety. Second, maintain a clean workspace. Remove flammable … Read more

Shielded metal arc welding (SMAW) is a process that joins metals using heat from an electric arc. The arc forms between a consumable electrode and the base material at the welding joint. This process creates strong coalescence of the metals, ensuring a durable connection. This process is accessible for beginners due to its simplicity and … Read more

Another benefit of AC welders is their ability to … Read more

Arc welding is a welding process that joins metals through an electric arc. This arc generates intense heat, melting the base materials so they can fuse together. The process usually requires equipment, including an electrode. The electrode can have different polarity, affecting how the heat and arc behave during the welding. There are several types … Read more

Submerged arc welding (SAW) is a welding process that uses an electric arc to generate heat between a continuously fed consumable electrode and the workpiece. A layer of flux covers the weld area, improving efficiency and preventing contamination. SAW is widely used in industry for effectively joining metals and producing deep welds. The process begins … Read more

Arc welding produces temperatures of about 5,500 °C (9,930 °F). In contrast, plasma welding can reach around 28,000 °C (50,400 °F). Both methods use partially ionized plasma. Plasma welding employs a constricted arc plasma. This allows for better control and improved weld quality in various welding applications. Both methods share similarities, such as the use … Read more
