Features gas welding brass
The presence of zinc in the composition of the brass of any brand reduces the thermal conductivity of the alloy and forced to use a reduced value of thermal power of the flame. As fuel gas is used acetylene, specific consumption of which (no more than 115…120 l/h per mm thickness to be welded) dimension is determined by the conditions of evaporation of zinc. This process begins at 9000 C, and is released during this poisonous vapor, and an undesirable overheating of the weld pool.
During the evaporation of the zinc is broken also continuity of the weld, and increases the likelihood since. All these features require the presence during welding strong oxidizer containing silicon compounds. Silicon binds the oxides formed during the welding process, and subsequently translates them into slag. Waste zinc drops several times.
When gas welding brass are recommended to use gaseous waste products. Their presence gives the finished seam strength and ductility. After welding the weld area immediately prokovyvayut to avoid undesirable growth of the grain and following from this nonuniformity of mechanical properties.
To purchase consumables for gas welding brass and brass semi-finished products finished alloys at the best prices from the manufacturer, the company offers Electrocentury-steel. The supplier ensures prompt delivery of goods to the point specified by the client.
Technology and sequence of welding
The above subtleties of gas-welding brass, lead to a high speed gas burner, with the simultaneous need to fully fill the area of the weld. Flame length should not be more than 6…10 mm, and the flame should be directed mainly on the filler wire.
Preparedness weld it process a draft using pneumatic hammers. The degree of deformation during forging is not to exceed 30…40%. Hand hammering degrades the uniformity of the mechanical properties of the alloy.
After precipitation the finished structure is subjected to annealing. Annealing temperature, depending on the brand of brass in the range of 600…6500 C and subsequent cooling should be done with the oven.
Since the desired flame temperature during gas welding is less than normal, instead of acetylene can be applied to other flammable gases — propanebutane mixture or even kerosene. The efficiency of the process increases. The oxygen flow rate is set higher than usual so that the flame was predominantly oxidizing.
The company Electrocentury-steel offers at competitive prices, to rent, forgings and weldments, made of brass of different brands and profiles. Supplier guaranteed timely delivery of goods to the point specified by the client.
