LESSON X WIRE-FLUX COMBINATION FILLER METAL GRADES (SAW) Ordinary Strength Higher Strength 1TM, 1T, 1M 1YTM, 1YT, 1YM 2TM, 2T, 2M 2YTM, 2YT, 3YM 3TM, 3T, 3M 3YTM, 3YT, 3YM 10.6.1.4 By using the table and grade notations in Figure 1, you can see that the grade ABS 2YSA signifies: (2Y) a tensile strength in the 71,000-95,000 psi range, a minimum yield strength of 54,000 psi, and a minimum elongation of 20% in 2 inches, meets the impact requirements of 20 ft.-lbs. at -4°F when welded semi-automatically, and 20 ft.-lbs. at 14°F when welded automatically: (SA) the wire-gas combination has been approved for semi-automatic and automatic welding. 10.6.1.5 In the annual ABS Listing, the approved electrode or wire diameter, welding position, shielding gas (if applicable) and type of welding current (AC or DC) are also listed. Each electrode or filler metal must be re-approved annually. 10.6.2 Lloyd’s Register of Shipping (LRS) - Lloyd’s Register of Shipping is a British ship classification society similar to the ABS. They also publish an annual approved filler metal listing with test procedures very similar to the ABS. 10.6.3 Det Norske Veritas (DNV) - Det Norske Veritas is a Norwegian ship classifica- tion society that operates very similarly to the American Bureau of Shipping and Lloyd’s Register. 10.6.3.1 ESAB has a number of filler metals on the approved list of each of the three ship classification societies. Since the listings change annually, they do not appear in this instructional material. Information on the listings of any specific product may be secured by contacting the Technical Services Department.
