In this segment of the video, the instructor demonstrates how to weld a 3/8 plate in a 1G position using a backing strip. They emphasize the importance of cleaning the plates and removing mill scale before welding. The backing strip used is a quarter inch in size and acts as a spacer between the plates. The instructor also shows how to tack the backing strip into place before welding. Additionally, they mention the importance of creating a landing on the plates.
00:03:00
In this segment of the video, the focus is on placing the backing strip in the center of the well evenly and securely. The instructions emphasize quartering the tacks and placing them strategically for stability. The welding setup includes a Lincoln Electric Power MIG 215 MPI machine for stick welding at 145 amps. The welding process involves crisscrossing the tacks and ensuring the backing strip remains steady. The goal is to achieve a clean and precise weld with a 3/8 plate and a 3/32 landing.
00:06:00
In this segment of the video, the speaker demonstrates how to tack the corner of a 45-degree piece. They then explain the technique for starting the root pass, emphasizing zigzagging up and down with pauses at the edges. The instruction includes feeding the rod continuously, creating a ramp-like weld away from the plate’s edge to avoid a messy appearance. The speaker highlights the importance of maintaining proper angles during welding with a stick rod.
00:09:00
In this segment of the video, the speaker demonstrates welding techniques for a root pass, hot pass, and stringers. Key actions include maintaining a consistent angle of 105°, counting while welding to ensure even coverage on both walls, and zigzagging the hot pass to fill the narrow groove. The importance of cleaning the welds after each pass, checking for imperfections, and adjusting techniques based on groove width is emphasized. The speaker advises starting with stringers once the groove widens. Remember to maintain a tight arc feed and avoid prematurely pulling out to achieve clean welds.
00:12:00
In this segment of the video, the focus is on performing fills in welding. The instructions emphasize dragging the metal across slowly and steadily, ensuring a good angle throughout. Key points include running fills from bottom to top, maintaining a consistent technique, and using 145 amps of power. After completing the fills, it is crucial to inspect for defects like porosity and remove any high spots by grinding to ensure a flat surface. The guideline for capping should be placed inside the well, and the cap should be dragged across following the guideline at 145 amps. It is important to stay inside the guideline and ensure it is visible in the puddle by following it closely while welding.
00:15:00
In this part of the video, the speaker explains why sometimes you can’t see your welding guideline due to leaving your face behind while welding. The key action is to move your face with your stick rod simultaneously to maintain visibility of the guideline. Adjusting the stick rod angle or lowering it can help unblock the view. It is emphasized to maintain the same angle and speed consistently throughout welding. The process of following the guideline is reiterated for the second and third caps. The details include using a 1/8 grinding disc, ensuring visible guidelines and using normal and steady pressure during welding.
