Las OAW (Oksi-Aseteline Welding) Pengertian, Sambungan dan Kampuh

Introduction

This tutorial provides a comprehensive overview of Oksi-Aseteline Welding (OAW), including its definition, requirements, and techniques for creating effective welds. OAW is a vital skill in metalworking, making it essential for professionals and hobbyists alike.

Step 1: Understanding OAW

• Definition: Oksi-Aseteline Welding (OAW) is a welding process that utilizes a flame produced by burning acetylene and oxygen.
• Applications: Commonly used in metal fabrication, repair work, and artistic metal projects.

Step 2: Preparing for OAW

• Equipment Needed:
  • Oxy-acetylene torch
  • Welding goggles
  • Welding gloves
  • Workpiece materials (metals to be welded)
• Safety Precautions:
  • Always wear protective gear to safeguard against sparks and intense light.
  • Ensure proper ventilation to avoid the buildup of harmful gases.

Step 3: Setting Up the OAW Equipment

• Torch Setup:
  1. Attach the oxygen and acetylene cylinders to the torch.
  2. Open the cylinder valves slowly.
  3. Adjust the gauges to the recommended pressure settings (typically around 5 psi for acetylene and 10-15 psi for oxygen).
• Lighting the Torch:
  1. Use a flint lighter to ignite the acetylene first.
  2. Gradually open the oxygen valve to achieve a neutral flame.

Step 4: Making the Weld

• Welding Technique:
  • Hold the torch at a 45-degree angle.
  • Move the torch in a smooth, steady motion along the joint of the workpieces.
  • Maintain a consistent distance from the workpiece for even heating.
• Filler Material:
  • If needed, introduce a filler rod into the weld pool to strengthen the joint.

Step 5: Inspecting the Weld

• Check for Quality:
  • Inspect the weld bead for uniformity and penetration.
  • Look for defects such as cracks or incomplete fusion.
• Common Pitfalls:
  • Avoid overheating the metal, which can lead to warping or burn-through.
  • Ensure proper joint fit-up before welding to minimize gaps.

Conclusion

Oksi-Aseteline Welding is a valuable skill that requires practice and attention to detail. By understanding the equipment, safety measures, and welding techniques outlined in this tutorial, you can successfully execute OAW projects. As you gain experience, consider experimenting with different metals and joint designs to enhance your welding proficiency.
