What is micro-arc welding? Micro-stainless steel covered electrode is often seen on Taobao, which is used for micro-arc welding of 0.5-3.0 mm thick stainless steel plates, pipes and other structural parts. If it is used to weld structural parts such as stainless steel pipes with a thickness of 0.5-3.0 mm, argon arc welding can be directly used. Why use such advanced equipment?

High-energy micro-arc cold welding is a new type of high-energy micro-arc pulse high-energy micro-arc cold welding processing equipment. High energy micro-arc alloy coating is a physical and chemical process. Because the heat generated by high-energy micro-arc will not be transferred to the surroundings in an instant, the local temperature of the electrode will rise sharply, exceeding the melting point or even boiling point of the electrode metal, so that the alloy at high temperature can be firmly coated on the surface of the part with local chemical changes, so that the surface properties of the workpiece are significantly strengthened and the surface geometry can be restored. The high-energy micro-arc cold welding process is based on the phenomenon of electric corrosion in gas environment and the phenomenon of anode material transferring to cathode during pulse discharge time.

HESD high-energy micro-arc cold welding process is different from welding, spraying or element infiltration. Simply put, it is a process between the two, which has some characteristics of welding and other processes, but also has unique advantages such as small heat input and metallurgical combination of welding layer and base metal. In some special applications, high-energy micro-arc cold welding technology makes up for the shortcomings of other technologies.

Traditional mechanical equipment, tools and molds are repaired by electric welding, argon arc welding and thermal spraying. Because of the high calorific value, the material of the workpiece is damaged greatly, so if the repaired workpiece is not handled properly, it is easy to produce internal stress and destroy the metallographic structure of the metal, so most machine tools are not suitable for traditional repair. Most car owners choose to scrap, and the production cost remains high. These are collectively referred to as disconnection repair. Destructive repair has become increasingly unsuitable for the strict requirements of modern science and technology society for mechanical equipment, tools and molds. In order to solve the problems of this era, a unique high-energy micro-arc cold welding came into being. Advanced nondestructive cold melting repair technology is to achieve the purpose of good combination, high strength and good repair without heating, deformation and damage to metal structure. Non-destructive cold melting repair technology has high repair output value and low repair cost, and can be repaired online on site. Non-destructive cold melting repair technology is a supplement and development to current manufacturing technology. Non-destructive cold melting repair of scrapped products is an extension and innovation of product life cycle management and an important technical way to achieve sustainable development.
