  1. INTRODUCTION TO WELDING MR. JANISCH 2004

  2. WELDING BASICS. • COURSE IS TAUGHT TO INDUSTRY STANDARDS. QUALITY IS JOB 1!! • WHAT IS SUPPLY • THE MOST MODERN EQUIPMENT AND MATERIALS • TEACH THE BASICS AND PROCEDURES FOR THE EQUIPMENT • INTRODUCTION TO THE WELDING INDUSTRY—COURSE JOB BASICS. • ARTICULATION WITH TECH SCHOOLS—GIVE YOU CREDIT. • WHAT YOU NEED TO SUPPLY. • BE READY TO WORK • DO THE ASSIGNMENTS—ON TIME AND BE HERE • NO STANDING AROUND OR SAYING “BECAUSE I DRESSED UP I CAN NOT DO ANYTHING” or “THE LOOK” • Requirements: • Safety Glasses & Welding Gloves—you can purchase from Mill Valley or pay $10 • Clothes required:--put in lockers • Recommend: • Old pair of shoes—you will burn them • Flannel shirt--made mostly of cotton—protect arms, upper body. • Pair of good work gloves • Ear Plugs??

  3. Welding Defined • A weld is defined by the American Welding society (AWS) as “a localized coalescence (the fusion or growing together of the grain structure of the materials being welded) of materials or nonmetals produced either by heating the materials to the required welding temperatures with or without the application of pressure, or by the application of pressure alone, and with or without the use of filler materials” • Welding—a joining process that produces coalescence of materials by heating them to the welding temperature, with or without the application of pressure alone, and with or without the use of filler material.

  4. Use of Welding • Construction—welds instead of bolts and rivets • Buildings, bridges, boats, military equipment • Some of aspects of welding are closely guarded secrets • Repairs of equipment • Art Construction

  5. Welding Processes • Oxyacetylene Welding (OAW) • Shielded Metal Arc Welding (SMAW) • Stick welding • Gas Tungsten Arc Welding (GTAW) • Gas Metal Arc Welding (GMAW) • Wire Welding, MIG Welding • Flux Cored Arc Welding (FCAW) • Torch Brazing (TB) • Flux Cored Arc Welding (FCAW)

  6. Selection of Joining Process • What determines what equipment to use for a job. • Availability equipment • Repetitiveness of the operation (how many passes) • Quality requirements (pipeline) • Location of the weld • Materials to be joined • Appearance of the finished products • Size of the parts • Time Available

  7. Occupational Opportunities in Welding • Welders • Tack Welders • Welding Operators • Welding Helper • Welder Assemblers/welder fitters • Welding Inspection • Welding Shop Supervisor • Welding Salesperson • Welding Shop Owners • Welding Engineers

  8. Training For Welding • Know the basics of welding, metals, welding symbols and working plans • Certification or Qualification. • Take a standardized Test • 9 month Program—Lake Area, Southeast • American Welding Society (AWS) • Entry Level Welder—beginning • Level II; • Level III
