The invention discloses a steel structure welding process applied in a low-temperature anoxic environment. A plurality of base materials to be welded are transported to a box-type preheating device with an automatic welding device through a feeding device, and the feeding device drives the welding process to be welded. The multiple base metals are close to each other in the box-type preheating device until the multiple base metals to be welded are butted in the box-type preheating device, and at least one joint to be welded is formed at the joint of at least two base metals, the box The type preheating device divides the preheating zone with the spot to be soldered as the center, and heats the preheating zone at the same time, and the automatic welding device welds the corresponding spot to be soldered after each preheating zone is preheated, so that more The two base metals are welded into a whole, and the feeding device transports the whole out of the box preheating. It realizes preheating and welding of the base metal in the process of conveying the base metal, which not only helps to improve the precision of preheating and welding, but also helps to simplify the structure and production process of the production line.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a steel structure welding process applied in a low-temperature anoxic environment. Background technique [0002] Welding is a manufacturing process and technology for joining metal or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Modern welding generally achieves the purpose of joining workpieces by three ways: fusion welding, pressure welding and brazing. Among them, fusion welding and brazing are the most commonly used. Fusion welding is to heat the workpieces to be joined so that they are partially melted to form a molten pool. After the molten pool is cooled and solidified, it is joined. Brazing uses a metal material with a lower melting point than the base metal as the solder. Wet the base metal with liquid solder, fill the joint gap, and diffuse with the base metal to achieve link welding. [0003] Due to the low temperatur...
