Zinc burnout

The presence of zinc forces users to strengthen safety measures when welding brass alloys. Zinc, as a more fusible component, in the process of heating the welding area begins to evaporate, making the weld porous, in addition, zinc vapor is a health hazard.

Regulations for welding brass with a semi-automatic machine

• Availability of effective exhaust devices, capable of removing fine zinc dust;
• Availability of a respirator on the welder;
• Thorough cleaning of the pieces to be joined from surface contaminants, traces of grease , etc;
• Grinding of the prepared surface to a characteristic "brass" shine. If acid solutions are used for this purpose, the surfaces are washed in a solution of neutral detergents and thoroughly dried;
• Conventional semi-automatic welding of thin (less than 4 mm thick) products is ineffective because the workpieces are rapidly heated. To bind the released oxygen it is necessary to use ceramic fluxes, electrodes with bronze cladding (silicon bronze is used), or additive brass wire containing silicon.

Supplier Evek GmbH offers to buy brass rolled products of domestic and foreign production at an affordable price in a wide range. We provide delivery of products anywhere in the continent. The price is optimal.

Sequence of welding

It is necessary to adhere to the following rules:

• Achieve as evenly as possible the melting of the brass, so the electrode is placed directly near the torch;
• Perform welding with the length of the seam not more than 20 ... 25 mm, and then perform forging the resulting seam, thus getting rid of a possible coarse-grained metal. Otherwise, strength and ductility will not be provided;
• Parameters of the arc in the periods between individual welding cycles should be gradually reduced to exclude overheating of the alloy and the subsequent vaporization;
• The welding seam should be filled to its full height during the main passage of the torch; underwelding is not allowed because of the danger of zinc vapor evolution;
• Use excessive supply of oxygen into the weld forming zone;
• As an additive to use brass wire with aluminum, silicon and boron.
