Best welding rods UK 2022

Welding requires the use of welding rods and sometimes a filler metal. Depending on the type of welding, electrodes, welding wire or welding rods are used.

Types of electrodes

Welding requires the use of an electrode and sometimes a filler metal. Depending on the type of welding, a welding electrode, welding wire or welding rods are used.
There are many types of electrodes. The use of one or the other will depend above all on the type of welding machine, the base metal to be joined, the position in which we are going to weld and the finish we want.

In manual or MMA welding, the most common electrodes are coated. They usually have a standard nomenclature consisting of the letter E and four digits. The E means it is an electrode for manual welding. The first two digits are the tensile strength, measured in pounds per square inch per 1000. For example, an E6013 electrode withstands the stress of 60,000 PSI and 7018 has the high tensile strength of 70,000 PSI. The third and fourth digits indicate the conditions (position, current, polarity) under which it can be welded successfully.

Depending on the predominant material in the coating, the electrode will be suitable for one metal or another.

For welding stainless steel, cast iron or hard steels, there are dedicated electrodes to handle with care.

Mild steel welding rods

Basic rod types are bare metal, coated with a light and heavy flux. The flux compounds keep oxygen away from solder and remove metallic impurities. You can also distinguish rods by the diameter of the metal core expressed in fractions of an inch (2.5 cm), the tensile strength of the rod, and the type of flux coating.

Stainless steel welding rods

The stainless steel electrode suffers from frequent sticking. The slag bursts during cooling, hence the wearing of protective glasses in addition to the welder’s hood when welding. Note that this electrode can be used on a mixed weld – example stainless steel-iron or stainless steel-hard steel etc.

Cast iron welding rods

The cast iron electrode should be handled gently. Just like the part to be welded, it must be preheated. Additional puzzle to be envisaged: the cooling of the elements to be assembled must be done slowly and gradually away from air to avoid cracking (placement of hot sand or gravel under and on the part to be welded).

In the MIG welding process, it is a steel welding wire, fed continuously via a wire feeder, which acts as both a fusible electrode and a filler metal. In addition to their composition, with different steel grades offered: carbon steel, alloy steel, stainless steel, aluminium and hard facing steel, the wires also stand out for their design; bare or solid wire requires the addition of gas for its fusion; the cored wire allows welding without gas even outside, thanks to a protective flux of the weld pool, consisting of rutile or basic powder. These MIG – MAG wires are available in spools. The coils are generally of a size corresponding to the capacities of the reels of the stations to be welded.
