  1. \u00a0The principle of selection should enable the mechanical properties of the weld metal to be essentially the same as the base material. In order to ensure the safe use of the structure, it must be stressed that the weld metal should have excellent plasticity, toughness and crack resistance. To this end, the actual strength of the weld metal should not be too high, generally should not be higher than the actual tensile strength of steel more than 50Mpa.<\/li>
  2. \u00a0For thick plates and constraint degree of the structure, it is advisable to give priority to ultra-low hydrogen type welding rod.<\/li>
  3. \u00a0For low alloy steel with yield strength not greater than 440Mpa, under the condition that the performance of the weld is the same, priority should be given to AC low hydrogen or ultra low hydrogen type welding electrodes with good process performance. When welding in poorly ventilated environments, priority should be given to low-dust, low-toxicity welding electrodes.<\/li><\/ol>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    1. The welding shop or section of the fabrication plant should have a welding material manager who is responsible for collecting welding material from storage, baking it as required and then issuing it to the welders. For welding rods taken out of the cryogenic tank and issued to the welders, the general amount of each issue should not exceed the amount used in 4 hours.<\/li>
    2. Baked and dried welding rods and fluxes can still be damp when placed in the air, therefore in the welding construction of building steel structures each welder is required to be equipped with a welding rod insulation cylinder.<\/li><\/ol>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
