Abstract

The invention discloses passive self-breeding high-heat carbon steel metal automatic welding pasty fluid. The passive self-breeding high-heat carbon steel metal automatic welding pasty fluid comprises a basic recipe composition and a bonding agent, and the weight ratio of the bonding agent to the basic recipe composition is 26:100. In addition, a preparing method and a using method of the passive self-breeding high-heat carbon steel metal automatic welding pasty fluid are further provided. According to the welding paste fluid, new reducing agents such as boron powder serve as burning ingredients, heat energy released by high-heat-release reactants after the high-heat-release reactants are ignited can sufficiently achieve metallurgical bonding between fusion welding materials such as burning products including copper and iron and welded base metal through mechanisms such as sufficient moistening, diffusion and reactive crystallization so that automatic welding can be achieved, and the carbon steel metal welding work can be efficiently, simply and conveniently completed at any special place and under any weather condition under the conditions that an external power source, an air source and other energy resources do not exist and no device and tool exist.

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 carbon-steel metals without self-propagating high-heat and its preparation method and use method. 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 without external...
