How to ensure the quality of the parts produced by the welding robot?

 Do you know what the welding robot has for welding rods? Let's talk about the requirements of welding robots for welding rods.

       Welding robots can use barreled coiled welding rods according to needs. In order to reduce the frequency of changing welding rods, welding robots should use barreled welding rods. However, due to the use of barreled welding rods, the wire feeding hose is longer, the resistance is greater, the quality standards for the stiffness of the welding rods are higher. When using welding rods with slightly weaker copper plating quality, the copper plating on the surface of the welding rod will fall off due to friction, which will cause the volume of the hose to decrease. When feeding wire at high speed, the resistance will increase, the welding rod cannot be smoothly fed, causing vibration, making the arc unstable affecting the welding quality. In severe cases, a jam will occur, causing the welding robot to shut down, so the welding rod hose should be cleaned in time.

       How does the welding robot ensure the quality of product workpieces?

       As a teaching reproducing intelligent robot, the installation quality precision of the standard product workpiece must have good uniformity.

       When using welding robots, the quality of component preparation should be strictly controlled to improve the precision of welded parts installation. The process performance, groove standard installation precision of components will affect the welding tracking effect. The quality of component preparation the precision of welded parts installation can be improved the following aspects.

       (1) Customize the welding method for welding robots impose strict process requirements on component standards, welding grooves, installation standards. Usually, the standard tolerance of components grooves is adjusted within ±0.8 mm, the standard error of installation is adjusted within ±1.5 mm. The probability of welding defects such as pores undercuts can be greatly reduced.

       (2) high-precision installation tools to improve the installation precision of welded parts.

       (3) The welding should be clean tidy, without oil stains, rust, welding slag, cutting slag other debris. Weldable topcoat is allowed. Otherwise, it will affect the arc initiation pass rate. The positioning welding is changed electrode welding to gas maintenance welding, the spot welding parts are polished at the same time to avoid residual slag shell pores due to positioning welding, thereby avoiding arc instability even spatter formation.
