Weld Deposition Rate

• 13 lb/hr MIG - [1]
• 25 lb/hr Metal core wire - [2]

Cost of a 200' Tower, 4' Diameter, 1/4" Wall Thickness

• Metal 3D printing - with MIG welders, 250 amp each at 30V
• Welding wire - $68 for 44 lb - [3]
• Alibaba shows 50 cents per lb - [4]
• 12' length of diameter. 12 SF per foot of height. 6" build per hour. 400 hours for tower, or just 17 days. Could possibly increase to 12 welders, at 8 days for the tower.
• This tower is 24000 lb - 120 lb/ft
• It would be useful to make wire for reduced cost. If produced from scrap, tower could cost not $24k but 1/10th.
