Efficiency In Welding

Effective efficiency is a ratio of heat output of this component of the heat balance to the thermal equivalent of electrical power arc. Calorimetric experiments showed that the effective efficiency the process of heating products welding arc depends on the conditions of its combustion and is depending on the method of welding: Submerged – 0,80 0,95 consumable electrode coated with quality – 0,70 0.85; in carbon dioxide – 0.58 0.72; in carbon dioxide cored wire – 0.70 0.85; non-consumable electrode in argon – 0.50 0.60; in argon mag – 0.70 0.80. Coefficient of heat decreases with increasing arc length and increases with the deepening of the arc in the weld pool. On efficiency affect and shape of parts in the welding area – the so-called geometric factor. For example, when beading open arc weld in Cutting efficiency values at 5 10% higher than the cladding onto the plane. With the deepening of the arc in the weld pool efficiency increases […]
