q(t) = сF(t)Рме/G (Вт),
где с - скорость звука в материале электрода, см/сек;
F(t) - площадь поперечного сечения электрода на уровне сварочной ванны; см2;
Рме - значение избыточного давления паров металла, г/см2;
G - безразмерный коэффициент Грюнейзена.1. A method of electric arc welding of products of a complex profile with a melting flat insulated electrode in an atmosphere of air, consisting in the fact that an electrode is fixedly fixed at the junction between the products to be welded with a terminal to which the terminal of one pole of the current source is connected, the second pole of which is connected to the article to be welded, electric is excited the arc between the end of the electrode and the product, move it along the end of the electrode, cool the molten metal of the weld behind the weld pool and when the bath comes to the end of the joint and they extinguish the electric arc, characterized in that the electrode is made of variable width - according to the shape of the joint, in addition, the instantaneous power of the current source necessary for welding is changed proportionally to the cross-sectional area of the electrode at the level of the weld pool, and the values of the welding power are determined by the formula
q (t) = cF (t) P me / G (W),
where c is the speed of sound in the material of the electrode, cm / sec;
F (t) is the cross-sectional area of the electrode at the level of the weld pool; cm 2 ;
P me - the value of the excess vapor pressure of the metal, g / cm 2 ;
G is the dimensionless Gruneisen coefficient.
