CONSTITUTION:Weld slag is the oxide contg. Si, Mn and Fe generated by deoxidation reaction in molten iron and the oxygen constituting this oxide is supplied mainly from the inside of the shielding gas into the molten iron. The shielding gas is mainly composed of Ar or He or a gaseous mixture composed thereof and includes CO2 or O2 or both thereof as the oxidizing gas. The gas shielded metal arc welding is, thereupon, executed at the amt. in the shielding gas satisfying the equation I and using the pulse currents in arc generation. In the formula I, X: the amt. of the CO2, Y: the vol.% of the amt. of the O2. The slag is, therefore, prevented and electrodeposition coatability is improved. The oxidation in a heat affected zone is suppressed and phosphate treatability is improved as well.

摘要： PURPOSE:To obtain an alloying hot dip galvanized steel sheet excellent in corrosion resistance with superior operation efficiency by subjecting a steel sheet to hot dipping and to alloying treatment and forming a film having a specific composition consisting of Fe, Al, Mg, Mn, Si, and Zn. CONSTITUTION:A steel sheet is subjected to hot dipping and to alloying treatment, and the content of Fe in a film on the resulting plated steel sheet is regulated to 7-17% by weight, and further, other components other than Fe in the film are regulated so that they consists of 0.3-2.4% Al, 0.5-2% Mg, 0.4-0.8% Nn, 0.005-0.3% Si, and the balance Zn with inevitable impurities. Among the components in the above film, Mg and Mn have a function of improving corrosion resistance. Moreover, the oxidation of a bath due to the addition of large amounts of Mg can be met by the addition of Al and the decrease in the alloying velocity due to Al can be met by the addition of Mn, and further, the excessive alloying accelerating action of Mn can be met by the addition of Si. By this method, the alloying hot dip galvanized steel sheet excellent in corrosion resistance can be obtained at a proper alloying velocity without causing the oxidation of the bath.

摘要： PURPOSE:To produce an alloying hot dip galvanized steel sheet excellent in corrosion resistance by incorporating specific amounts of Al and Mg or further Cu and/or Co into a plating layer at the time of applying alloying hot dip galvanizing to the surface of a steel sheet. CONSTITUTION:At the time of producing an alloying hot dip galvanized steel sheet used for automobile body, building material, household electrical appliance, etc., hot dipping is carried out by passing a steel sheet through a hot dip galvanizing bath, as a hot dipping bath, containing prescribed amounts of Al, Mg, and Cu and/or Co. Subsequently, heating is applied to the resulting plated steel sheet, e.g. up to 500 deg.C to subject Fe in the steel sheet and Zn in the plating bath to mutual diffusion, by which an alloying hot dip galvanizing layer which has a composition containing, by weight, 7-20% Fe and also containing, in the case where the total content of Zn, Al, Mg, Cu, and Co, excluding Fe, is 100%, 0.1-2% Al, 0.2-2% Mg, 0.1-1% Cu and/or Co is formed. By this method, the alloying hot dip galvanized steel sheet having extremely superior corrosion resistance can be obtained.
