  • Deoxygenation of boiling steel is incomplete, oxygen content is high, phosphorus and other impurities distribution is uneven, local overspending, aging sensitivity and cold brittle sensitivity are high, hot cracking tendency is added. If unqualified electrode is used, if the content of carbon and sulfur in the weld metal is too high, cracks will occur. For example, when factories use acidic electrodes to weld Q235-A steel, the high carbon fernoganese in the electrode coating will lead to thermal cracks in the weld.

  • Hot wire is made of high quality low carbon steel, high carbon steel, after drawing, hot galvanized processing galvanized wire. Hot dip galvanized wire production process: wire rod – drawing – annealing – drawing – annealing – galvanized. Hot dip galvanized wire has the characteristics of thick coating, strong corrosion resistance and solid coating. And according to the special needs of users, according to the industry standard to provide various specifications of galvanized wire. Hot-dip galvanized wire is of better quality than electrodip galvanized wire. In the production process, hot dip galvanized wire has more than one annealing process, so the corrosion resistance of hot dip galvanized wire is stronger than that of electric galvanized wire.
