Packaging & Delivery
Packing Detail of carbon steel weld neck flanges: Pallet
Delivery Detail of carbon steel weld neck flanges:30-45days
The processing skills of the carbon steel weld neck flanges develop rapidly, and the flange has a variety of physical and chemical functions such as strong oxidation, low melting point, fast thermal conductivity, large coefficient of linear expansion, and large latent heat of melting, so when selecting welding, it often presents some simple problems.
First, the blank should be strictly finished by chemical or mechanical methods before welding to eliminate the oxide film on the surface. When argon tungsten arc welding, choose AC power supply, after the "cathode finishing" effect, remove the oxide film. For gas welding, use a flux that removes the oxide film. When the thick plate is welded, the welding heat can be increased, and the large standard melting gas maintenance welding may be selected. In the case of direct current connection, the cathode finishing is not required.
Second: In the process of welding of carbon steel weld neck flanges, a lot of heat can be quickly conducted to the matrix metal inside, so in the welding of aluminum and aluminum alloy, in addition to the energy spent in the molten metal pool, there is more heat unnecessary to spend on other parts of the metal, the consumption of this useless energy is more obvious than that of steel, in order to high-quality welding joint head, should try to choose energy convergence, power, power, power, etc. Sometimes preheating and other process methods can also be selected.
