ARC Welding

Sound pressure arc welding describes the noise produced during welding, usually ranging from 85 to 110 dBA. This sound results from the ignition of the arc and metal transfer. Welders can lower their noise exposure by reducing air pressure to 80-90 psig. Measuring audible sound helps assess welding quality and its health impact. In order … Read more

Arc welding creates an electric arc between an electrode and metal. This arc generates sparks as it melts material in the weld puddle. This welding process is key in metal fabrication, allowing the joining of aluminum, stainless steel, and carbon steel. It supports custom fabrication through accurate machining methods. The benefits of using spark and … Read more

Shielded metal arc welding (SMAW), also called manual metal arc welding, is a welding technique that uses a consumable electrode. As the electrode melts, it forms a protective cover. This cover shields the weld area from oxygen and atmospheric gases. SMAW is versatile and widely used across different industries. Beginners should also learn about equipment … Read more

Shielding gases for gas metal arc welding (GMAW) include argon, helium, CO2, and oxygen. Argon suits aluminum, while CO2 works well with mild and carbon steel. Each gas has specific benefits and drawbacks. Choose the right gas based on the base materials to achieve the best welding results. Argon provides excellent arc stability and increased … Read more

The AWS D1.1 SMAW Structural Welder Certification verifies a welder’s skills in flat (3G) and overhead (4G) positions. It allows welding on unlimited thicknesses with a 1” plate. Passing the certification tests in 3G and 4G qualifies the welder for all positions. A welding kit is provided for the tests. Planning and preparation are vital … Read more

Shielded metal arc welding (SMAW) with direct current reverse polarity (DCEP) connects the electrode to the positive terminal and the workpiece to the negative terminal. This setup improves penetration and reduces inclusions. It is particularly effective for welding thin materials and metals that melt easily. Maintaining the correct arc length is also crucial. A shorter … Read more
