Energy storage resistance welding cold welding machine, also known as mounter (micro-pulse mounter). This kind of welding machine uses steel plate and powder as repair materials, and uses the contact resistance between the repair materials and the workpiece to repair defects. The picture is shown on the left. The advantages of this machine are: low price, no need of argon protection, easy to carry, suitable for mobile operation, especially suitable for repairing defects with depth less than 0.50 mm

1. It is smaller, lighter (the main engine weighs only 8Kg) and has higher power.

2. Microcomputer control, intelligent adaptation to different thickness of materials, different workpieces and different welding head sizes. Power distribution is more reasonable, and digital display and operation are more intuitive and convenient.

3. Switching power supply technology can still ensure stable high power output and welding quality when the voltage fluctuates within the range of 220 V 20%.

4. Separate the precision welding mode from the precision welding head to provide more support for precision operation.

Argon shielded high energy cold welding machine.

Argon shielded high-energy cold welding machine, also known as imitation laser welder. This kind of welding machine uses filament as repair material, and fuses the repair material with the workpiece by accurately controlled high-energy arc, with good bonding force. The picture is as shown on the left. The advantages of this machine are: high power and fast repair speed. It can be widely used in all kinds of steel, copper, aluminum and related alloys, especially for a large number of repairs.

1. High welding strength: completely metallurgical welding, deeper penetration, and the effect is comparable to that of laser welding.

2. High repair precision: round wire filler can be used for repair, without losing the original datum plane, with less redundant solder and easy post-shaping. The minimum repair amount is 0.3mm (using 0.3mm diameter patch).

3. Fast repair speed: the fastest repair amount can reach 100mm3/min.

4. Small damage to the substrate: small hot spots will not cause annealing deformation of the substrate.

5. Easy to carry: the whole machine is small in size and light in weight, 9kg.

Argon-shielded EDM precision cold welding machine

Argon-shielded EDM precision cold welding machine, also known as multifunctional metal surface strengthening cold patching machine. This kind of welding machine uses flux-free welding wire or covered electrode to remove the coating as the repair material, and uses spark instantaneous discharge to transfer the electrode material to the surface of the workpiece to be repaired, so that the welding material and the workpiece are metallurgically fused into a whole. Can repair metals such as steel, copper and aluminum.

1. Easy to install and operate.

2. The welding strength is high, and the weldment has no annealing, crack and deformation, and can pass various flaw detection tests after processing.

3. Welding wires or covered electrode with various hardness are used, and the welding materials range is wide, and the diameter is below 4.0mm..

4. The repair speed is fast and the repair accuracy is high.
