Micro forging - welding process and equipment

Abstract

The invention discloses a micro-forging-welding process and equipment, including a welding workbench, two welding parts are fixedly installed on the top of the welding workbench, a connection gap is arranged between the two welding parts, and the front end of the connection gap is fixed A welding structure is provided, a welding structure is arranged above the rear end of the welding structure, the bottom of the welding structure is set as a welding nozzle, the top of the welding nozzle is fixedly connected with an insulator, and the top of the insulator is fixedly connected with a welding head, and the welding There is a welding wire connection block fixedly connected in the middle of the top of the head. The micro-forging-welding process and equipment of the present invention adopts the forging-welding combined welding connection process, which completely changes the organizational state of the welding structure, from a relatively loose cast state to a forged state, and the stress It is basically released in the forging process. Therefore, the combined forging-welding process will completely change the original welding structure concept and scope of application, greatly improve the comprehensive performance of the joint, and is not only a new revolution in the field of welding industry.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a micro-forging-welding process and equipment. Background technique [0002] According to the statistics of the World Iron and Steel Association, the world's steel output is 1.239 billion tons. According to comprehensive estimates of relevant data, the world's welding material output is about 6 million tons. The ratio of steel output to welding materials is that the annual welding volume and welded structure account for about 70% of the total. That is, 840 million tons. For this reason, we can see how important the proportion and position of welded connection structures in the world industry are. [0003] my country's steel consumption may reach 600 to 700 million tons. The substantial increase in steel output affects the rapid development of the welding industry. The increasing demand for welding equipment has increased employment opportunities in the welding indust...
