Company Description

TOKO brand Welding rods, Flux Cored Welding Wire, Stainless Steel Welding Rods, Al-alloy Welding wire, TIG Welding wire, MIG Welding wire, Welding Flux etc products are designed for energy conservation & environment protection, at the same time separately approved by China Classification Society(CCS), Lloyd' s Register of Shipping(LR), American Bureau of Shipping(ABS), Bureau Veritas(BV), Germanischer Lloyd(GL), Det Norske Veritas(DNV), Nippon Kaiji Kyokai(NK), Korea Register of Shipping(KR), Pt. Biro Klasifikasi Indonesia(BKI), Canadian Welding Bureau(CWB) as well as Lloyd' s Register Quality Assurance (LRQA) etc.

TOKO brand AWS A5.1 E7018 electrode is the most popular low-hydrogen covered electrode type in use today. It features certain characteristics that separate it from other classes. this class of covered electrode is an ideal choice for all-position welding, with the exception of downhill welds. They offer smooth, quiet arc characteristics with low spatter levels and easy slag removal, making E7018 a desirable electrode to use by welders of all skill levels. They provide weld deposits with medium penetration levels, ensuring good fusion to the base metal. Another benefit, made possible with the addition of iron powder in the coating, is a relatively high deposition rate.


TOKO AWS A5.20 E71T-1C is a most popular flux cored wire designed for single or multi pass welding having a smooth arc transfer, low spatter, flat to slightly convex bead contour, with a high deposition rate and easily removal slag. this all-position wire has excellent feeding and low fume generation using 100% CO2 making it a good choice for mild steel and higher strengths steels. Argon - CO2 gases may be used if tested with application.


Self-shielding flux-cored wires do not require an external shielding gas. with this type of electrode, the weld pool is protected as gas is generated when the flux from the wire is burned. Because the self-shielding wire produces its own protective shield and doesn' t require an external gas tank, it is more easily carried about.

Advantages of Flux-Cored Wire Electrodes
There are several advantages of using flux-cored wire electrodes. these advantages include but are not limited to:

They allow for a high deposition rate. They work well outdoors and in windy conditions.
with the right filler materials, these electrodes can make FCAW an " all-position" process.

Typically, flux-cored wires create clean, strong welds. Disadvantages of Flux-Cored Wire Electrodes There are concerns with any type of welding method. Regardless of the process and type of electrode used, there is the possibility of creating an incomplete fusion between the base metals. Slag inclusion or cracks in the welds may also result.


Solid Wire Electrodes
Solid wire electrodes are used in Metal Inert Gas Welding. Such electrodes require a shielding gas, which is delivered from a pressurized gas bottle. The shielding gas protects the molten weld pool from atmospheric contaminants.

Solid wire electrodes are often made of mild steel which is plated with copper to prevent oxidation and to aid in electrical conductivity. The copper plating also helps to increase the life of the welding contact tip.
