Ding Testing Inspection: Macroscopic Metallography of Weld Joints, Key to Ensuring Welding Quality
In the field of metal processing, welding technology is widely used in industries such as construction, mechanical manufacturing, aerospace, and more, due to its efficiency and cost-effectiveness. However, defects that may occur during welding, such as porosity, slag inclusion, incomplete penetration, and cracks, can severely affect the performance and safety of weld joints. To ensure welding quality, Ding Testing Inspection provides professional macroscopic metallography testing services for weld joints to accurately assess their quality.
Service Introduction
Since 2023, Ding Testing Inspection (DTI) has been witnessing over 500 batches of material testing and corrosion tests each year by internationally renowned inspection agencies, under the supervision of well-known inspection agencies, with international leading user recognition, and recognized by top-tier manufacturers and engineers in the industry!
Ding Testing Inspection's macroscopic metallography testing service for weld joints uses professional metallographic microscopes to meticulously observe the macroscopic structure of weld joints, assessing the characteristics of the weld metal, fusion line, heat-affected zone, and base material, and identifying potential internal defects. This service can promptly detect issues during the welding process, providing crucial evidence for improving welding techniques.
Industry Pain Points
Welding defects can lead to a decline in material performance and even cause safety accidents. Traditional testing methods may not fully identify welding defects, especially those at the microscopic level, requiring more specialized testing services to ensure welding quality.
