Joe Magee was an animated character created by General Electric in 1942 to present the subject of arc welding, and always seems to do the "wrong thing". The original series consisted of six, ten minute films; but in this re-release they are condensed and extended into two, 20 minute films. This provides an in-depth overview of welding in vertical and overhead positions, focusing on the challenges posed by gravity and how proper technique can overcome them. It emphasizes the four key factors for successful welds: current setting, electrode angle, arc length, and travel speed. In vertical welding, a weld foundation must be built to support the molten pool, and techniques like momentarily removing heat help control metal flow. Overhead welding demands even more precise control due to the molten metal's tendency to fall, requiring strategic electrode positioning and manipulation. The also discusses the causes and effects of magnetic arc blow, particularly in DC welding, and shows how using alternating current (AC) helps neutralize this issue for more stable welds. Finally, it reviews various electrode types—such as cellulose, rutile, low hydrogen, and iron powder—highlighting their ideal applications and the importance of selecting the right electrode for each welding task. 0:31 – Introduction to vertical welding, emphasizing the effect of gravity and the importance of four main factors: current setting, electrode angle, arc length, and travel speed. 1:07 – Description of the limits of the vertical position and recommended settings for a 5/32" E6010 electrode. 1:52 – Explanation of how to build a weld foundation in vertical welding to control the molten pool. 2:44 – Role of electrode coating, shielding gas, and slag in protecting the weld. 3:20 – Post-weld inspection for proper fusion, ripples, and weld face. 4:08 – Comparison of proper vs. improper welds with a focus on spatter and wasted material. 5:14 – Overview of vertical groove welding, including weaving techniques for wide openings. 6:18 – Second layer welding for both groove and fillet welds, with emphasis on fusion and undercut avoidance. 6:37 – Transition to overhead welding, noting its wider limits and unique challenges. 8:13 – Demonstration of overhead welding techniques for fillet and groove welds using proper angles. 9:47 – Formation of gas shielding and slag during overhead welding and importance of weld appearance. 10:19 – Dealing with arc blow using angle adjustments and maintaining proper arc length. 12:06 – Impact of current settings (too high or too low) on weld quality and control. 12:55 – Effects of travel speed: too fast causes poor fusion; too slow leads to excess metal and rough welds. 13:51 – Overhead groove welds and layering techniques, especially for wide grooves. 15:00 – Introduction to magnetic arc blow, how it affects welds, and why it’s worse with DC. 17:02 – Visual explanation of magnetic deflection of the arc using a magnet. 18:01 – Alternating current (AC) as a solution to arc blow due to reversing magnetic fields. 19:37 – Benefits of AC welding: stable arc, good welds with minimal arc blow. 20:36 – Recap of the four welding principles and electrode selection. 21:17 – Overview of different electrode types (cellulose, rutile, heavy mineral, low hydrogen, iron powder) and their applications. 22:30 – Reminder to consult electrode guides before first use. Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
