LEARNING ELECTRIC WELDING FOR BEGINNERS | 3 WELDING TECHNIQUES THAT MUST BE Mastered

Summary

In this welding tutorial, the presenter shares three fundamental techniques every beginner should master: Zigzag, Spiral, and Overlap welding. These techniques are ideal for various metal thicknesses, with the Zigzag and Spiral methods perfect for thicker materials (5mm or more) and the Overlap method suited for thin materials (under 2mm). The presenter explains each technique in detail, offering practical tips and advice for better welds. Whether you're new to welding or looking to refine your skills, this video provides essential knowledge for your welding journey.

Takeaways

• 😀 The video introduces three essential welding techniques that every welder should master.
• 😀 The techniques are frequently used in electrical welding workshops and are suitable for both beginners and professionals.
• 😀 The first technique demonstrated is the Zigzag welding technique, ideal for thicker metal pieces (5mm and above).
• 😀 Zigzag welding involves moving the electrode alternately between sides, providing an easy-to-understand approach for beginners.
• 😀 The second technique is the Spiral welding method, where the electrode moves in a circular motion between sides.
• 😀 Spiral welding is also suitable for thick metals (5mm+), and it’s commonly used in welding workshops.
• 😀 The third technique is Overlapping welding, which is used for thin metals (under 2mm), like hollow sections.
• 😀 Overlapping welding requires making consecutive welds that overlap by about 50%, increasing the speed for thinner materials.
• 😀 The video emphasizes the importance of preparation before welding, such as ensuring the workpiece is properly secured to prevent movement.
• 😀 The presenter uses a 1200W welding machine with NK-68 electrodes (2.6mm) and type E 6013, showcasing the tools and materials used in the process.
• 😀 The video concludes with a clean-up of the welds, highlighting the finished results of each technique, and encourages viewers to subscribe for more tutorials.

Q & A

What are the three welding techniques discussed in the video?

The three welding techniques discussed are Zigzag Welding, Spiral Welding, and Overlap Welding.

Why is it important to tack the workpiece before welding?

Tacking the workpiece ensures that there is no movement or warping due to thermal expansion during the welding process.

What type of welding machine is being used in the video?

The video uses a 1200-watt transformer welding machine.

What is the role of the NK-68 wire in the welding process?

The NK-68 wire is used as the welding electrode, and in the video, it comes in two sizes: 2.6mm and Type E 6013.

Which welding technique is most suitable for thick metals above 5mm?

Both Zigzag Welding and Spiral Welding are suitable for welding metals that are thicker than 5mm.

What is the primary difference between Zigzag Welding and Spiral Welding?

In Zigzag Welding, the electrode is moved back and forth between two sides, while in Spiral Welding, the electrode is moved in a circular motion, making a spiral pattern.

What is Overlap Welding, and what is it typically used for?

Overlap Welding involves creating weld beads that overlap the previous bead, and it is ideal for welding thin materials such as hollow pipes under 2mm in thickness.

What should be considered when welding thin metals?

When welding thin metals, it's essential to work quickly to avoid burn-through and ensure the correct technique, such as Overlap Welding.

What is the purpose of cleaning the weld area in the video?

Cleaning the weld area ensures that the weld is smooth, tidy, and free from impurities that could affect the quality of the joint.

How does the thickness of the workpiece affect the welding technique used?

Thicker workpieces require techniques like Zigzag or Spiral Welding, while thinner workpieces are best welded using Overlap Welding to prevent burn-through.
