How to choose a welding wire

Some manufacturing processes involve the use of various methods for welding refractory materials and metals. To do this, use welding equipment, industrial gases and all kinds of consumables, including welding wire.

Since welding wire is used where the connection of parts must be performed at the highest level, its choice should be approached with due care. If you select the welding wire correctly, you can get a flat, durable, resistant to tearing and corrosion, as well as a plastic weld. So, how to choose a welding wire?

Remember classification

When choosing this welding material, it is important to remember that there are various types of welding wire, which differ in characteristic features: the structure of the rod, the chemical composition and the presence of the alloying component. In accordance with these characteristics, three groups of welding wire are distinguished: with a low carbon content; with a small amount of alloying elements, as well as a wire with a high content of alloying elements. Each of these large groups includes subgroups depending on the structure of the wire..

Various welding processes involve the use of copper-plated, steel or surfaced flux-cored wire. To select a suitable type of welding wire, it is necessary to familiarize yourself with the marking line, where those parameters that affect the welding process.

In cases where submerged arc welding of important parts that will be under high loads in the future will be used, it is better to give preference to surfacing flux-cored welding wire. It allows you to perform any production processes associated with the connection of metal parts made of carbon steel. Products processed with this wire can withstand high temperatures and pressures..

In those cases where the wire will be used for welding low alloy steel, then it is preferable to purchase a steel wire whose surface is copper-plated. Thanks to its use, the surface of the weld will receive additional protection, in addition, it will prevent corrosion and abrasive processes. In addition, this material will increase the stability of the welding arc, as well as reduce spatter during welding. Copper-plated steel welding wire is best used for welding low-carbon metals and alloy steel..

When you decide on the type of welding wire, pay attention to the diameter of this material. The thickness of the welded steel or metal sheets depends on it..

We reviewed, how to choose a welding wire. These recommendations and tips will help you choose exactly the material that will be optimal for your goals..
