Abstract
The invention discloses a research method for influencing factors of surfacing welding process performance parameters, S1, material preparation: test equipment: argon arc welding machine, using Fenghuo WSE-350 AC and DC pulse argon arc welding machine, the minimum welding current is 10A, the maximum The welding current is 350A, and the pulse current, pulse base value time, and gas hysteresis shut-off time are all adjusted steplessly; test materials: welding rods are 2Cr13 welding rods and D502 welding rods; welding body: 38 CrMoAl nitrided steel; lubrication conditions: 5W‑20 #Machine oil, when the present invention adopts 2Cr13 electrode to carry out overlay welding, under certain argon gas pressure, optimize the process parameter after welding current, can make its wear resistance improve more than 3.8 times, when adopting 2Cr13 electrode to carry out overlay welding, under certain argon pressure The process parameters after optimizing the welding current under gas pressure can increase the wear resistance by more than 1.7 times, and the wear resistance can be increased by setting the argon pressure value and welding current value.
Description
technical field [0001] The invention relates to the technical field of surfacing welding technology for rolls, in particular to a research method for influencing factors of surfacing welding process performance parameters. Background technique [0002] The roll is the transportation part of the steel rolling roller conveyor. Every time the steel plate roll is transported to the middle and upper reaches, the quality of the steel plate on the stick surface affects the surface quality of the steel plate, but the surface of the stick surface is affected by the friction of the periodically changing steel plate. Wear, burns, scratches and fatigue fractures occur on the rolling surface that has been in service for a long time, which affects the working accuracy of the rolling surface and thus affects the surface quality of the steel plate. Steel bars are in high demand. Therefore, surfacing welding can be used not only to repair the failure parts caused by service, but also to str...
