16. SMAW ELECTRODE CLASSIFICATION

17. OBJECTIVES: At the end of the lesson, you will be able to learn; Identify welding codes in SMAW electrode classification weld material using the given electrode according to its classification Value the importance of welding codes in SMAW electrode classification

18. Trade terms: Electrode – means one of the point through which electricity passes through

19. Tensile Strength – ability to determine the yield strength. Trade terms:

20. Tolerance – the allowable range from the standards. Trade terms:

21. TRADE TERMS: Welding Position – 1F,2F,3F,4F,1G,2G,3G,4G,5G,6G

22. Hydrogen - is a chemical element; it has symbol H and atomic number 1. TRADE TERMS:

23. Amperes - a measure of the amount of electricity flowing and helps determine the heat generated during the welding process.  TRADE TERMS:

24.   SMAW Electrode Classification (E7018) E ---------Electrode 70 --------Tensile Strength or 70,000 Pounds Per Square Inch 1 --------- Welding Positions 8 --------- Hydrogen Content 18 --------Current Setting and Dark glass number

25. Position 1G, 2G, 3G, 4G, 5G, 6G 1F, 2F, 3F, 4F

26. Electrode Coating: (Science 8) (week 8 Periodic Table of Elements) (S8MT-IIIi-j-12) Respiratory problems: Welding can produce harmful fumes that can be inhaled, leading to respiratory problems such as asthma or metal fume fever.

27. 1-3 low hydrogen content equivalent to 10 – 7 hours of welding 4-6 med Hydrogen content equivalent to 6 – 4 hours of welding 7-9 high Hydrogen content equivalent to 2 - 1 hours of welding

28. Current setting: (Physics Grade 8) week 5&6 (relationship between current and voltage) (S8FE-Ig- 29) V = voltage, I = current, and R = resistance. 

29. The last two digit number will determine the current setting of the welding machine to be used. (Tolerance must be observe) Example: (E7018) 18 equals to 100 – 180 amps. (E 6013) 13 equals to 100 – 130 amps.

30. The four most widely used electrode diameters are: 3/32” 1/8” 5/32” 3/16”
