Roller Arcing 
Isoarc 453

Characteristics
Easy to use with both AC and DC positive polarity. Hardly any slag remains on the welds which are ideal for multiple layer applications. The high chrome content enables the deposit to withstand corrosion and heat attacks of up to 500°C.

Applications
Specifically designed for applications requiring multi-pass layers and resistance to scouring, ISOARC 453 is widely used in the sugar industry for refurbishing crusher rolls. Also used on grinders, digger parts, paving breakers, clamping jaws, anvils, impeller worms and scraper blades. It is ideal for large area surfacing.

Procedures
Stringer bead or weaving may be used. Medium to short arc recommended to obtain smooth surface finish. An arc length of up to twice the electrode diameter is advisable. Surface cross cracking will occur and is normal with high hardness deposits. Deposits are non-machinable.

Structure
Chrome carbide in a martensitic structure.
