  • DC and AC in welding, what should I choose?

    Welding can choose AC welding machine, can also choose DC welding machine. When using a DC welder, there are positive and negative connections, taking into account factors such as the welding rod used, the condition of the construction equipment and the quality of the weld.Compared with the AC power

  • Gas welding carbon dioxide cylinder site to reduce the method of moisture

    In the welding process, if the carbon dioxide gas in the cylinder contains high moisture, serious porosity will occur during the welding process. So measures should be taken at the welding site to reduce the water content of the gas as much as possible.The methods are as follows.1. Turn the carbon d

  • Causes of cold cracks in welding

    Cold cracking is a more common type of cracking in welding production, which occurs when the weld is cooled to a lower temperature, for low-alloy high-strength steels, around the martensitic transformation temperature. The three elements of cold crack formation are the hardening tendency of the stee
