Abstract

The invention discloses passive self-breeding high-heat pasty fluid for automatic stainless steel welding. The passive self-breeding high-heat pasty fluid comprises a basic recipe composition and a binding agent. The weight ratio of the binding agent to the basic recipe composition is 29:100. The invention further provides preparation and using methods of the passive self-breeding high-heat pasty fluid for automatic stainless steel welding. The pasty fluid for welding adopts boron powder and other new reducing agents as combustion components, heat energy released by a reagent which has the high exothermicity after being ignited is sufficient to enable combustion products such as copper, iron, nickel and fusion welding materials to be metallurgically combined with welded parent metal through wetting, diffusion, reactive crystallization and other mechanisms, and therefore automatic welding is completed; welding work of metal like carbon steel is efficiently, easily and conveniently completed under the situation that no external power sources or gas sources or other energy sources or no other devices or tools are used on the condition of any special places and weathers.

Description

technical field [0001] The invention belongs to the field of metal welding, and relates to metal solder, in particular to a paste for automatic welding of stainless steel without self-proliferation and high heat, and a preparation method and application method thereof. Background technique [0002] China is the largest manufacturer of welded steel in the world, and there are about 7,000 enterprises with welding as the main technology. Welding technology plays an indispensable and important role in many fields. Modern advanced technologies, such as laser and arc composite heat source welding, plasma arc welding, fine plasma arc cutting, and CNC cutting systems, have been widely used. However, the above-mentioned process methods all require equipment and additional tools, as well as a large amount of energy, without exception, in performing welding operations. Traditional methods such as electric welding and gas welding also have the fatal disadvantage of being unable to work...
