Abstract

The invention discloses a welding method for energy storage seam welding of wire mesh, which comprises step 1: cleaning the parts to be welded, selecting a test piece to carry out positioning welding trial welding, energy storage seam welding trial welding and tearing test, and determining the positioning welding Welding parameters and welding parameters of energy storage seam welding; step 2: assemble the parts to be welded and check whether the overlap is qualified, and then perform tack welding on the parts to be welded with qualified overlap according to the welding parameters of tack welding; step 3: put The parts to be welded after tack welding are performed energy storage seam welding according to the welding parameters of energy storage seam welding. Energy storage positioning welding and energy storage seam welding are carried out through the process route and process parameters determined by the process test of the present invention. The welding quality is reliable, the appearance of the weld seam is beautiful, a large number of welding burn-through and burn phenomena are avoided, and the qualified rate of parts is less than 50%. % has increased to more than 90%, and the welding efficiency has increased by 3 times.

Description

technical field [0001] The invention belongs to the field of welding technology, and relates to an energy storage seam welding method for wire mesh. Background technique [0002] The current fuel nozzle adopts a two-stage oil filter, and the filter screen of the auxiliary oil filter adopts an ultra-thin wire mesh welded structure. The wire mesh weaving method is flat mesh weaving square hole mesh, the precision grade is A grade, the basic size of the mesh and the diameter of the wire are very small, both within the range of a few tenths of a millimeter. [0003] The welding method of this part is energy storage lap seam welding. The lap width, the diameter of the welded part, the width of the weld, and the length of the weld are all at the millimeter level. At the same time, because the thickness of the part is very thin, it is only 0.1mm. In actual work, it is found that using the energy storage welding welding method for welding is very prone to burn-through during the po...
