Analysis of the Causes of Welding Defects

2026-09-14

Welding Qualityis the core factor in structural safety, appearance quality, performance compliance, and delivery acceptance. During routine production welding, various welding defects can easily occur due to nonstandard operating techniques, unreasonable parameter settings, inadequate workpiece preparation, environmental factors, and other issues.

     To further standardize on-site welding procedures, unify operating processes, correct habitual errors, prevent and eliminate welding quality problems at the source, and improve weld formation quality, strength, and appearance pass rates, we are providing a detailed explanation of the ten common welding defects found in production, their causes, and reference images. This will guide all personnel in carrying out standardized construction, precisely controlling details, and comprehensively ensuring that product welding quality meets process standards and inspection requirements.

     The following is a description of ten welding defects and their causes. Let us analyze them together to guide on-site work, correct improper operations, and prevent problems, thereby ensuring that product welding quality meets the specified requirements.
