1. AWE-16A ELECTRO-SPARK DEPOSITION WELDING MACHINE
AN EASY WAY TO REPAIR YOUR
CASTING DEFECTS &
SAVING YOUR COST

2. There are blow hole defects and sand hole defects problems for all foundries.
Normally around 5-15% will have such problems (gray iron/ductile iron
castings and non-ferro castings). Most of the defects will appear after
machining.
All of the defect castings will become foundry returns if they can not be
repaired. For re-melting those foundry returns will have more cost - power
consumption / labour cost / raw material cost etc.
To use ATOM AWE-16A welding machine will repair those defect castings and
save your cost up to 10-30%
ATOM AWE-16A is suitable for: Ductile iron casting / Gray iron casting /
Aluminum casting / Copper casting and other non-ferro castings.

3. Foundry mould need to be repaired frequently, due to some damages will
happen to make the surface not smooth any more, this will affect the final
products.
Instead of replace with a new mould, to use ATOM AWE-16A welding
machine will repair those problems, after polishing the damaged mould will be
just like a new one.
Different welding rod materials are available for different metals.
It can also be used for repairing machinery parts and hydraulic equipments.

4. ◆High technology : Over 20 improvements, Use chopped wave soft switch
technology and DSC processor, digital control and very accurate output.
◆Power : Inverter power, energy conservation, environmental protection, high
efficiency, stable, light and smart.
◆High precision welding : Big current output range, Suitable for Ductile Iron;
Gray Iron; Stainless Steel and Non-ferrous metal (Aluminum , Copper etc. ), can
repair blow hole and sand hole defects, welding speed more quickly.
◆High welding intensity : With high single point power output, each point of
welding material is combined with the welding molten state to the substrate ,
forming metallurgical combination, produce very strong combination, minimal
chromatic aberration. Easy to operating, any one without professional training
can use and no pollution while using.
◆Other usage : Can also be used for repairing of mould; hydraulic equipments;
machineries etc.

8. Working principle of AWE-16A:
Electro-spark deposition process is to use the high-energy power stored and release instantly
between electrode and matrix with high frequency release, through air ionization channels
formed between the electrode and matrix to generate an instant high temperature, high
pressure micro-region. While ion state of the electrode materials in micro-melt into the matrix,
forming metallurgical combination. Not only due to quenching of metal surface to form
martensite, and also deposition process of the narrow transition region to form ultra-fine
austenitic organization. So electro-spark deposition process is not normal welding or coating
process.
