Greater carbon dioxide content generally increases the weld heat and also increases spatter, especially when it comprises more than 20 percent of the shielding gas. Hàm lượng carbon dioxide lớn hơn thường làm tăng nhiệt hàn và cũng làm tăng sự lan tỏa, đặc biệt khi nó bao gồm hơn 20 phần trăm khí bảo vệ.
Ti forms TiN and therefore prevents the grain growth in slab heating and, in addition, it prevents the grain growth in the welded heat affected zone to thereby enhance the tough ness owing to fine microstructure of base metal and the welded heat affected zone. Ti tạo TiN và do đó ngăn ngừa sự tăng trưởng hạt trong sưởi ấm tấm và, ngoài ra, it prevents the grain growth in the welded heat affected zone to thereby enhance the tough ness owing to fine microstructure of base metal and the welded heat affected zone.
