step by step learn to stick welding for beginners

Summary

In this video, the host provides a step-by-step guide to electric welding, starting with the preparation of the workpieces by grinding the sides of the plates to ensure a stronger weld. Using 2mm RD260 electrodes and a 70-amp setting, the process involves making spiral, circular motions with the electrode. The video also covers the importance of proper amperage and the use of a welding inverter. After welding, the result is cleaned, and viewers are encouraged to practice and refine their technique. The host concludes with tips for better welding results and a reminder to subscribe for more tutorials.

Takeaways

• 😀 Start by grinding the sides of the plates to make them thinner, which helps expand the melting space during welding.
• 😀 The more melted electrodes during welding, the stronger the connection between the workpieces will be.
• 😀 After welding, use a grinder to level the connection, ensuring it remains intact and doesn't separate.
• 😀 If there’s a gap in the middle when you paste the workpieces together, use a 2mm electrode for a 3mm thick workpiece.
• 😀 When welding, move the electrode in a spiral, similar to a stacked circle, to ensure proper coverage and connection.
• 😀 Set the welding inverter to 70 amperes for a 2mm electrode, as every 1mm electrode requires about 30 amperes.
• 😀 Always connect the ground (negative) clamp to the workpiece before starting the welding process.
• 😀 Use a circular, spiral motion with the welding electrode to create an even weld joint.
• 😀 Turn off the welding inverter after use, setting the amperage to 0 and switching off the generator set.
• 😀 Clean up any leftover electrode material by knocking it off with a sharp iron, ensuring a smooth, clean weld surface.
• 😀 The quality of welding can improve with practice and better electrode movement, resulting in stronger welds.

Q & A

What is the first step in preparing the plates for welding?

The first step is to grind the sides of the plate to make them thinner. This helps to expand the melting space during welding, which results in a stronger connection.

Why is it important to grind the edges of the plate before welding?

Grinding the edges helps to create a larger melting space for the electrodes, which ensures a stronger and more durable weld.

What type of electrodes does the instructor recommend for the welding process?

The instructor uses RD260 type electrodes, specifically 2mm in diameter for this particular welding task.

How does the instructor suggest moving the welding electrode during the process?

The welding electrode should be moved in a spiral motion, circling like a stacked circle, to ensure an even and consistent weld.

What is the recommended amperage setting for welding with a 2mm electrode?

The instructor recommends setting the welding inverter to 70 amperes when using a 2mm electrode. This is slightly higher than the standard 30 amperes per 1mm electrode, to ensure a more mature and solid weld.

What is the reasoning behind setting the amperage slightly higher than the standard 30 amperes per mm of electrode?

Setting the amperage higher helps ensure the welding result is more thorough and the weld becomes more solid and durable.

What should you do before starting the welding process?

Before welding, you should first connect the ground or 'mass' (min) to the workpiece. This is an important safety step to complete the electrical circuit.

How does the instructor recommend extinguishing the welding process once completed?

To stop the welding, you should press the red button on the welding inverter to the off position and set the amperage to 0. Additionally, turn off the generator set.

What should be done after the welding process to clean up the workpiece?

After welding, any leftover electrodes should be knocked down using a sharp iron. Once the electrodes are removed, the workpiece should be cleaned thoroughly.

How can the quality of the welding result be improved?

The quality of the welding can be improved by being more consistent and diligent in moving the welding electrodes. This ensures better coverage and a more solid weld.
