SZ-08 high frequency welding machine China factory Supplier's Choice

Multiple functions:

It can not only be used for deposition welding, surface strengthening, but also for weld mending to ferrous metals including ductile iron, gray iron, stainless steel and nonferrous metals likecopper and aluminum.

4.Machine & accessories of SZ-08: (include electrode/ welding wires)

Cold welding machine principle:

Cold welding machine is using arc spark effect in the air. Electrode material made of alloys is sparking dissolved and deposited on the metal work piece.
1: Charge: The condenser is charged when electrode and work piece is separated.
The temperature of the spark point is approximately 25,0000°C, however, no heat accumulation occurs during diffusion and deposition periods since the pulse period is extremely short compared to the interval period.

2: Electro Spark: Electro spark between electrode and base material, only contact area temperature will be approximately 25,0000°C.

Mainly Applications

1.Multiple usage: Have the function of welding, surface hardening etc 

2.1Reparing range: Casting products, such as sand hole. Rebuild/restore worn parts.etc
2.2Non-ferrous metal workpeices
2.3Injection mold/die casting: welding & repairing of worn mold, scratches, etc. The zinc & aluminum die casting and also surface strengthening of cavity to prolong their using-life

3.Easy to operate, can do surfacing rebuilding after welding.
4. Fast speed, high efficiency than common welding.
5. The repair effect is better than traditional Arc welding, TIG welding, laser welding, etc. It is very suitable for small defect parts. Very large defect is not available.

How to choose suitable cold welding machine?

01. Casting iron parts, nonferrous metal parts welding/ repairing, choose ESD (electrical spark deposition) cold welding machine; (our machine model XKS-01, XKS-02, SZ-3000, SZ-08).

02. Casting steel parts, precise work pieces welding/ repairing, choose precise cold welding machine/ intimate laser welding machine. (Our machine model SZ-1200, SZ-1100).

03. Soldering / welding together: only for stainless steel, steel, and aluminum sheets, choose precise cold welding machine/ intimate laser welding machine. (Our machine model SZ-1200, SZ-1100).

04. Weld mould flat surface wear out, oversize/dimension out of tolerance, choose model SZ-1200 or TXKS07-3.

COMMON WELDING WIRE/ ELECTRODE USED IN COLD WELDING MACHINE:

750E: Nickel alloy cold cast iron wire, mainly used for repairing nodular cast iron, grey cast iron and ordinary cast iron work pieces.
Copper alloy: Suitable for copper products repair, and aluminum mold, aluminum wheels and all kinds of aluminum products repair.
700T: Nickel cast steel welding wire is low temperature resistance cast steel welding wire/electrode, mainly used for welding /soldering the engine and higher casting steel component parts.
SKD11: Weld cold working steel, stamping die, hard cutting tool and high hardness surface work pieces. This welding wire/electrode has high hardness, wear resistance and high toughness.
H13-8407: Zinc, aluminum and other non-ferrous die casting metals, also can be used for hot forging or stamping mould, can weld hot punch rolling groove, cutting knife, etc.
C12: Weld repairs blanking die, cold forming dies, cold die, etc.
S50C: Weld steel mechanical parts of medium carbon steel welding, after welding hardness is not too high, there will be no stomata, can do milling.
SKD-61: Welding aluminum, zinc die-casting, aluminum and copper heat hot die, forging die, copper aluminum die-casting mould, etc.
MLK-SCM-29: Suitable for welding nickel chromium iron alloy steel, and other nickel alloy steel.
MLK-CU-63: Suitable for welding electrolysis, copper alloy, steel, bronze, cast iron, general copper parts, etc.
