VIDEO 8 Sambungan Fillet (T-Joint) Horizontal/ 2F

Summary

This tutorial provides a comprehensive guide to performing a 2F fillet weld in the horizontal position. The video covers essential techniques, from setting up the workpieces and selecting the appropriate electrode to controlling the travel angle and welding speed. Viewers will learn the step-by-step process, including tips on positioning the electrode, achieving consistent weld beads, and troubleshooting common issues. The tutorial aims to help both beginners and experienced welders master this specific welding technique for strong, durable joints.

Takeaways

• 😀 The tutorial covers the process of welding in the 2F position (horizontal fillet weld).
• 😀 The video provides step-by-step instructions for proper electrode placement and movement.
• 😀 Electrodes used are of type T60 13 with a diameter of 3.2 mm, and the recommended amperage is 100A.
• 😀 The importance of keeping the workpiece centered and perpendicular during the welding process is emphasized.
• 😀 Welding should begin by ensuring the electrode is placed correctly at the corner, with a 90-degree angle to the workpiece.
• 😀 The welding technique involves a controlled movement with consistent speed to create an even weld bead.
• 😀 A semi-tank method is used for creating a smooth weld on the reverse side, ensuring balance and consistency.
• 😀 The electrode should be positioned at the top of the workpiece for certain passes to maintain the correct angle and avoid overheating.
• 😀 The process involves multiple passes: the first pass covers the main weld, while subsequent passes help reinforce and cover the weld completely.
• 😀 At the end of the process, it’s important to check the quality of the weld by inspecting the three different passes for uniformity and strength.

Q & A

What is the topic of the tutorial?

The tutorial focuses on the 2F fillet weld technique, specifically in a horizontal position.

What is the 2F position in welding?

The 2F position refers to the fillet weld made in the horizontal position, where the workpiece is placed flat and the weld runs along the joint.

What welding electrode is used in this tutorial?

The tutorial uses an electrode type T60 13 with a diameter of 3.2 mm.

What is the recommended amperage for the welding process?

The recommended amperage for the electrode is between 60-120 A, with 100 A being the preferred setting.

What is the purpose of the first weld pass?

The first weld pass is intended to establish the primary joint, ensuring proper penetration and fusion before further welding.

How should the welder position the electrode during the first weld pass?

The electrode should be positioned at the corner of the joint, with the angle between the base metal and the electrode being approximately 70 to 90 degrees.

Why is it important to control the speed of travel when welding?

Controlling the travel speed is crucial for maintaining a consistent weld bead, preventing defects such as undercuts, and ensuring proper heat distribution.

What is the significance of the 'semi-tank' technique mentioned in the tutorial?

The 'semi-tank' technique refers to reversing the welding direction to fill in the weld from the opposite side, ensuring even fusion and strength across the joint.

What is the second weld pass focused on?

The second weld pass focuses on welding the opposite side of the joint, ensuring complete coverage and a solid, strong weld bead.

How should the welder position their body during the welding process?

The welder should ensure that their body is positioned comfortably, with the electrode at the correct angle and a stable, controlled motion to avoid unnecessary fatigue and errors.
