Iron welding

The iron welding process

Ferrous material welding is a process to permanently join two sheet metal parts continuously, ensuring strength and reliability. Not all iron alloys lend themselves well to welding, the best are those with low carbon content, no lead and limited sulfur. Therefore, it is necessary to know the chemical composition of the base metal in order to choose the right, suitable welding process that will ensure a good, reliable weld without defects.

How iron welding is done

Weldable ferrous materials lend themselves to all the key welding processes from electric arc welding such as TIG and MIG/MAG to laser welding and resistance welding. It is very imports to prepare the surfaces, which must be clean and free of contaminants to prevent defects such as cracks and porosity. The correct choice of filler material and welding gas is equally important for good, defect-free welding.

What machinery is needed for iron welding

To weld ferrous materials, Minifaber has a large fleet of welding processes with state-of-the-art systems suited to a range of production needs. 

Our equipment includes:

• MIG/MAG systems: ideal for medium to high thicknesses, fast welding, high productivity, and when the edges to be welded are not perfectly in contact.

• TIG systems: perfect for low to medium thicknesses, when good welding penetration is desired without deforming the sheet metal.

• Resistance welding equipment: effective for joining overlapping sheets or welding pins and bushes to sheet metal.

Each welding source controls the basic parameters for making defect-free repetitive welds.

The advantages of iron welding and how it differs from other materials

Ferrous materials generally exhibit good weldability, but this is not true of all iron alloys, so it is necessary to know the material and choose the correct welding process. Ferrous materials are used and welded for a variety of applications, from structural to pressure vessels and much more. 

Compared with aluminum, ferrous materials are more weldable, and even compared with stainless steels they have fewer critical issues and need less care. 

Thanks to our experience and advanced technologies, at Minifaber we can provide welding that meets the highest quality standards required by our customers.
