John T. Herrera: Welding Torch Tip Inventor & His Memorabilia By Heinz Davila SED 511 Professor Nava M 6pm-9:45pm

John T. Herrera Patent # 4,013,227 March 22, 1977 Welding Torch Tip Invented a welding torch tip that is used in welding ferrous metals with MAPP gas. The torch tip that he invented has a chamber that allows oxygen and MAPP gas to mix safely and be more efficient. Invented a welding torch tip that is used in welding ferrous metals with MAPP gas. The torch tip that he invented has a chamber that allows oxygen and MAPP gas to mix safely and be more efficient. Prior to Herrera’s invention, welding was done with other gasses that were not as fast and efficient as MAPP Gas. Herrera played a big roll on improving the welding industry. Prior to Herrera’s invention, welding was done with other gasses that were not as fast and efficient as MAPP Gas. Herrera played a big roll on improving the welding industry.

MAPP Gas MAPP Gas is a liquefied petroleum gas mixed with methyl acetylene propadiene. MAPP Gas is a liquefied petroleum gas mixed with methyl acetylene propadiene. The gas is more efficient because of its high combustion able temperature and its welding abilities with certain metals. The gas is more efficient because of its high combustion able temperature and its welding abilities with certain metals.

The students will then be shown a short video on the welding industry and the profession. The students will then be shown a short video on the welding industry and the profession. Finally the class will be shown slides of previous inventors and how they’ve been remembered through their stamps. Finally the class will be shown slides of previous inventors and how they’ve been remembered through their stamps.

Guided Group Practice: The first group practice will start out with the students creating eight to ten thumb sketches that are 3” by 3” in newsprint paper of their stamp. The thumbnails should include either Mr. Herrera, his invention, or both in the sketches. They will replicate the previous slides they saw about stamps.

Enrichment: For those students who need to be challenged, they can create life size stamps to put together a booklet of stamps. Enrichment: For those students who need to be challenged, they can create life size stamps to put together a booklet of stamps. Independent Practice: The students will now individually create the final stamp out of 11” by 14” poster board. The design should include similarities to stamps that they viewed in the previous slides. The students will now individually create the final stamp out of 11” by 14” poster board.
