Welding robots have any specifications about welding rods. Do you know? Let’s talkabout the requirementsof welding robots on welding rods

       Welding robots can use barrel plated welding rods as required. In order to reduce the frequency of electrode replacement, welding robots should use barrel welding electrodes, but because barrel welding electrodes are selected, wire feeding hoses are longer, resistance is large, quality specifications such as stiffness to electrodes are high. When the electrode with slightly weaker copper plating is used, the copper plating on the surface of the electrode will be reduced due to friction the internal volume of the hose will be reduced. When the high-speed wire is fed, resistance will be added, the electrode will be sent smoothly, which will cause vibration make the arc unstable. Welding quality. In severe cases, a stuck condition occurs, which causes the welding robot to shut down, so the electrode hose must be arranged in time.

       How to ensure the quality of product workpieces by welding robot

       As a teaching-reproducible intelligent robot, the installation quality precision of the product parts must be well unified.

       The use of welding robots should strictly control the quality of parts preparation improve the precision of welding parts installation. The process performance of parts, groove specifications installation precision will affect the welding tracking effect. The quality of parts preparation installation precision of welded parts can be improved the following aspects.

       (1) Special welding methods for welding robots will be customized, strict process requirements will be imposed on parts specifications, welding grooves installation specifications. Normally, the tolerance of parts groove specifications is adjusted within ±0.8 mm, the installation specification error is adjusted within ±1.5 mm. The probability of welding defects such as blowholes undercuts during welding can be greatly reduced.

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

       (3) Welding should be clean tidy, free of debris such as oil stains, rust, welding slag, cutting slag, etc. Solderable topcoat is allowed. Otherwise, it will affect the pilot arc passing rate. Position welding is changed electrode welding to gas maintenance welding. At the same time, the spot welding part is polished to avoid the slag shell pores caused by the position welding, thereby avoiding the instability of the arc even the formation of splashing.
