During the use of resistance welding equipment, welding problems may occur from time to time, affecting production efficiency and product quality. don't worry! This article will provide a detailed analysis of common welding problems and offer practical solutions to help you easily tackle these challenges.
Non penetration is one of the most common problems in the welding process of resistance welding equipment. Have you ever encountered situations where the welding area cannot be fully fused? This may be caused by the following reasons:
Low temperature at the top interface: There is not enough heat at the welding site to melt the workpiece.
The top forging is too small: the forging pressure is insufficient, which cannot fully bond the welding parts.
Low forging pressure and speed: Insufficient pressure and speed during the welding process result in poor welding performance.
Excessive metal inclusions: Impurities on the surface or inside of the workpiece affect the welding effect.
Solution
Adjust welding parameters: Increase welding current, time, and pressure appropriately to ensure sufficient heat and pressure at the welding site.
Cleaning the surface of the workpiece: Remove impurities and oxide layers from the surface of the workpiece to ensure welding quality.
Welding misalignment is another headache inducing issue. Have you found that the position of the welded parts is inaccurate? This may be caused by the following reasons:
Misalignment or tilting of welded components: The alignment of the components was not carefully checked before welding.
High temperature of welded components: High temperature may cause component deformation and affect alignment.
Excessive discharge length: Excessive discharge may cause instability in welded components.
Solution
Improve equipment stiffness: Ensure the stability of welding equipment and reduce vibration during the welding process.
Control the discharge length: Reasonably control the discharge length to avoid component instability caused by excessive length.
Check alignment: Carefully inspect the alignment of the welded components before welding to ensure accurate positioning between them.
White spots are unique defects on the weld seam, manifested as radial gray spots on the cross-section. These defects, although thin, may have an impact on the quality of welding. White spots are more sensitive to cold bending, but have a relatively small impact on tensile strength. Have you encountered this problem during the welding process?
Solution
Optimize welding process: Adjust welding parameters to ensure even distribution of heat and pressure during the welding process.
Strengthen quality control: Strengthen quality inspections during the welding process, promptly identify and address white spot issues.
Case 1: Solution to Non Penetration Problem
A certain factory found that the welding part did not penetrate during the welding of stainless steel components. After inspection, it was found that it was caused by low welding current. The problem was solved by appropriately increasing the welding current.
Case 2: Solution to Welding Misalignment
A car parts manufacturing company found that the position of the welded parts was inaccurate. After analysis, it was found that it was caused by misalignment of the welded components. The problem was effectively resolved by carefully checking the alignment of the components before welding.
By analyzing the causes of these problems and adopting corresponding solutions, welding quality and production efficiency can be effectively improved. Here are some practical suggestions:
Regular maintenance of equipment: Ensure that welding equipment is in good working condition.
Optimize welding process: Adjust welding parameters according to actual needs to ensure welding quality.
Strengthen quality control: Strengthen quality inspections during the welding process, promptly identify and address issues.
