1G Plate Stick Welding | SMAW

Summary

In this instructional video, Roscendo Rodriguez from South Coast Welding Academy in Houston, Texas, demonstrates the process of welding on a one-inch plate in a 1G position using a 332 liner. He emphasizes the importance of cleaning the plate, proper tack welding, and maintaining a consistent angle and technique throughout the process. Rodriguez provides detailed instructions on starting the root pass, hot pad, hub pass, and fill pass, highlighting the need for attention to detail and practice for achieving a high-quality weld. He concludes with tips on capping the weld and offers resources for further learning and discounts on welding supplies.

Takeaways

• 🛠️ Clean the back and front of the one-inch plate, ensuring a half-inch clean area around the edges.
• 🔥 Use a 332 liner with 7018 332 for welding on thick plates like the one-inch plate, which retains a lot of heat.
• 💺 Position the 332 liner as a spacer, ensuring a proper landing on both plates.
• 📐 Tacking is crucial; apply tacks at the corners of the plates, being mindful of the arc length and puddle connection.
• 🔧 Quarter your tacks to prevent uneven pulling during the welding process.
• 🌐 Start the root pass by warming up the metal from a distance and then move forward, using a stitch technique.
• 📐 Maintain a 60/10/18 angle while welding, adjusting as necessary to keep the keyhole centered.
• 🔄 Zigzag technique is used for the hot pass at 130 amps, ensuring full coverage from wall to wall.
• 🚫 Avoid rushing and ensure proper stacking by continuously feeding during the welding process.
• 💡 If imperfections occur, they can be evened out without worry, as long as the overall technique is followed correctly.
• 🌟 Cap the weld carefully, either slightly under flush or perfectly flush, and grind any high spots for a clean finish if allowed.

Q & A

What is the main topic of the video?

The main topic of the video is demonstrating the process of welding on a one-inch plate in a 1G position using stick out technique.

Where is Roscendo Rodriguez welding taking place?

Roscendo Rodriguez welding is taking place at South Coast Welding Academy in Houston, Texas.

What type of liner is recommended for welding on a one-inch plate?

A 332 liner is recommended for welding on a one-inch plate.

How should the 7018 332 liner be prepared for use?

The 7018 332 liner should be bent to be used as a spacer, and care should be taken to ensure a good 332 landing on both plates.

What is the purpose of tacking the plate?

Tacking the plate helps to secure it in place before starting the welding process, ensuring stability and accuracy.

What is the key technique for warming up the metal during the welding process?

The key technique for warming up the metal is to start from the back and move forward, using a stitching motion and maintaining a consistent angle throughout.

How should the keyhole be managed during welding?

The keyhole should be managed by adjusting the angle of the rod if it starts to shift, ensuring it remains centered and maintaining proper penetration and fusion.

What is the recommended amperage range for the hot pass?

The recommended amperage range for the hot pass is 130 amps, plus or minus, indicating a very hot process that requires care.

What is the welding technique used for the hot pass?

The welding technique used for the hot pass involves zigzagging from wall to wall, feeling both walls with the tip of the rod, and maintaining a consistent speed and angle.

How should the final cap of the weld be done?

The final cap of the weld should be done by following a guideline, ensuring the puddle is in the center of the guideline, and maintaining a consistent speed and angle without rushing or bouncing.

What advice is given for dealing with imperfections in the welding process?

Imperfections can be managed by evening them out, and if grinding is allowed, any high spots can be ground down for a cleaner finish. Practice is emphasized for improvement.
