Welded 1 foot long and 1/2 inch thick vertical up angle iron welds using 3 full weld beads and 2 foot long half inch thick vertical up tee-welds using 3 full weld beads. Bended tube pipe: circle and square frames (both projects require welding the final two edges together). Completed: Bended tube pipe: circle and square frames, FCAW self-shielded angle iron, FCAW gas-shielded angle iron, SMAW E7018 angle iron, FCAW self-shielded tee-weld, and SMAW E7018 tee-weld. Weld characteristics: FCAW angle iron: (Self-shielded has 100% smooth weld bead tie-in, however gas-shielded has 50% smooth weld bead tie-in). SMAW E7018 angle iron: (Weld bead irregular and does not have smooth tie-in). FCAW tee-weld: (Self-shielded has 80% smooth weld bead tie-in). SMAW E7018 tee-weld: (weld bead does not have smooth tie in).
