Shielded metal arc welding (SMAW) is a manual welding method. It uses a consumable electrode that is protected by a cover. As the electrode melts during welding, the cover also melts. This process shields the weld area from oxygen and other atmospheric gases. SMAW is important for creating strong, quality welds in many applications. SMAW … Read more

4130 steel, a low alloy, has high tensile strength (670 MPa) and yield strength (435 MPa). It meets specifications MIL-S-18729C for arc welding. The preferred filler metal is ER80S-D2 due to its strength. 4130 steel also offers good toughness and weldability, making it ideal for aerospace applications. Essential properties of 4130 steel include excellent weldability, … Read more

For successful 4G arc welding, clean the mill scale around the bevel using a sander or grinder. Maintain a 1/4” gap. Set the amperage for a tight arc without sticking the rod. Use a slight drag angle to achieve optimal results in your stick welding test. Next, focus on your travel angle. For overhead welding, … Read more

Arc welding in 3D printing uses an Arc Welder to change GCode from linear G0/G1 commands to curved G2/G3 commands. This process simplifies GCode, improves printing speeds, and produces smoother prints. Wire Arc Additive Manufacturing (WAAM) makes metal parts by layering metal wire with an electric arc. In comparison to conventional 3D printing methods, 3D … Read more
