Cold Welding Machines for Metal & Hybrid Materials Junction.
The cold welding machine is applicable and suitable for industrial welding repairing demands. Also, the workpieces which are made of metal materials (including copper and aluminum) can be repaired other than the materials and hard alloys of low melting points such as zinc and tin, etc.
The application is that it can work for local wearing generated during the application process of equipment and moulds.
Cold Welding Machine Working Principle
Metal Mold Repairing Machine employs (AC-DC-AC-DC) technology, which can convert the power into low voltage and large current DC power. By using the micro-computer technology to perform the accurate controlled welding time, as a result, cold weld machine can release the converted energy (in the form of instantaneous over-pulse arc between the tungsten electrode and workpiece). The arc of ultra-high temperature can finally make the metal workpiece together with welding wire fuse and splice.
Furthermore, the feature of cold welding machine is a short period and less heat. It can complete the fuse process — the welding wires and workpieces within tens of milliseconds. Therefore, rather with ordinary welding machine (more than a few seconds), this cold welding machine is less heat conduction to the workpieces. In addition, it has the advantages of less heat and lower temperature risen beyond the welding spots, also without annealing and discoloration. Due to the stress directions of welding spots scatters, hence the concentrated stress to the workpiece is relatively smaller. In conclusion, the workpiece deformation is smaller after being welded.
Since the output of the pulse energy, the machine is concentrated. Therefore, It can carry out copper and aluminum welding repairs, which is difficult for other ordinary welding machines.
General Information About Cold Pressure Welding
High Welding Strength
The cold welding machine has a full metallurgical fuse, the repairing places can be subject to milling and filing and other post-process.
High Repairing Precision
Round wires can be used to repair. It’s without losing the original base level, less redundant solders, and easy for post-phase shaping. The minimum repair amount is 0.05mm (filling material of 0.05m in diameter is used).
Fast Repairing Speed
Fastest repairing amount is up to 100 /min.
Less Damage to Base Materials
Cold welding machine has small hot spots, without causing annealing and deformation of the base material.
Reasonable Distribution of Power
It adopts microcomputer chip control and various materials of different diameters can obtain the best power.
Large Adaptive Range of Voltage
Switching power supply is used. When the voltage changes fluctuate within the range of ±20%, this machine can work in normal state and maintain a stable output power.
Convenient for Electricity Connection
With a quick connector, it is very convenient for connection and installation.
Easy to Carry
Small size of the whole machine (375×150×230), lightweight:9kg.
