The keyhole effect in plasma arc welding happens when the plasma jet produces high burning heat. This heat creates a deep hole in the workpiece. As the arc moves, molten metal flows around the keyhole and solidifies, forming a strong weld bead. This method ensures efficient and precise welding. Several techniques enhance the keyhole effect. … Read more

The keyhole technique in plasma arc welding utilizes high plasma gas pressure. It forms a “keyhole” at the seam, melting the material completely. This method effectively welds high-alloy and unalloyed materials in sheets up to 8 mm thick. It also allows for single-pass welding using square butt joints. One of the primary benefits of the … Read more

Keyhole welding by plasma arc uses high-pressure plasma gas to create a “keyhole” in the material. This melting process penetrates the material fully, allowing for efficient welding of high-alloy and unalloyed sheets up to 8 mm thick in a single pass. The technique typically employs a square butt joint for precision. The process begins with … Read more

A Job Safety Analysis (JSA) for arc welding identifies hazards such as burns, electric shock, and inhalation of fumes. It recommends safety measures like wearing Personal Protective Equipment (PPE), including gloves and eye protection. Key practices also include using fireproof screens and conducting Industrial Hygiene sampling to ensure safety. When conducting a JSA, start by … Read more

Lack of penetration in arc welding happens when the weld bead does not reach the joint’s root, resulting in an incomplete weld. To fix this, increase the current, lower the welding speed, or change the joint geometry. Addressing these factors is essential for creating a strong and effective welding joint. Techniques to achieve better penetration … Read more

When TIG welding aluminum, a jumping arc might occur due to low amperage and poor tungsten preparation. Use the right current for stability. Grind the tungsten electrode to a point. Remove aluminum oxide for a clear path. These adjustments help create a stable puddle and improve your welding technique. Control issues may stem from inadequate … Read more

To keep arc welding cords off the ground, ensure they have proper insulation to prevent electrical hazards. Use grounding methods to secure the ground cable near the welding area for safety. Wear dry insulating gloves and check all cables for insulation. This helps maintain current capacity and reduces risks during welding. Secure welding cords with … Read more
