The Servo-Spaw welding company offers welding of copper and brass.
Brass welding:
Welding this material is a difficult welding process due to the high zinc content.
Due to the high content of this element, appropriate knowledge and welding skills are necessary to ensure that the welding process of the material runs smoothly and that no air bubbles are formed under the welding surface.
We undertake welding of elements such as high-current rails, for the production of which brass is used.
What is brass welded with?
-
Brass TIG welding in an inert gas shield is often used to repair castings and join phosphor bronze sheets. Brass welding by this method is a complicated process, because brass is a difficult metal to weld due to the zinc content mentioned at the beginning.
-
Brass welding using the MIG method is the most common process when it comes to welding connections. It requires the use of a special wire that acts as a filler metal. In addition, this process involves the use of so-called shielding gases, such as gas mixtures with oxygen, carbon dioxide or argon.
Copper Welding:
Welding copper is a complicated process because it has the highest heat conductivity of all materials. The entire process of creating a weld pool requires much more time because in order to create it, copper must acquire the appropriate temperature, and here we mean the entire element.
How to weld copper?
-
Copper welding using the MIG (Metal Inert Gas) method is performed in a shielding gas of inert gases, such as argon or a mixture of argon and helium. Copper is welded with direct current, and the surfaces do not require preheating or other treatment than removing impurities and oxides. The method is fast and economical, but the quality of welds may be lower compared to other techniques. It is important to choose the right filler metal, preferably low-alloy copper wires, which will provide better joint strength.
-
TIG (Tungsten Inert Gas) copper welding is one of the most precise copper welding techniques. It uses an electric arc created between a non-consumable tungsten electrode and a copper welded surface. The shielding gas is most often argon, sometimes with the addition of helium. TIG copper welding provides aesthetic and high-quality welds, free from pores and other defects. This method allows for full control over the process, which is especially important when welding thin elements. The only disadvantages of the method are its time consumption and higher cost.
