8 Most Common Welding Defects, Causes & Remedies

When weld defects form in a weld they can weaken the joint. In some cases, this results in complete failure of the weldment. In serious cases, there can be severe consequences to a failing weld. So, you need to understand the various common welding defects. But in addition, you must know how to prevent them from

PPE

What is PPE & What PPE to Use when Welding?

PPE stands for Personal Protective Equipment. It refers to specialized clothing, equipment, or gear that is designed to protect individuals from various workplace hazards, environmental dangers, or infectious materials.

EN ISO 10204 2.1, EN ISO 10204 2.2, EN ISO 10204 3.1, EN ISO 10204 3.2

Difference in EN ISO 10204 2.1, 2.2, 3.1 & 3.2

EN ISO 10204 is a standard that specifies requirements for the inspection and testing of metallic products. The differences between the various types of inspection certificates defined by EN ISO 10204 are as follows:

Mechanical Properties of Metals

The physical characteristics of materials that allow them to withstand applied forces or loads are referred to as mechanical properties. The performance of materials in diverse applications is greatly influenced by these properties. Mechanical properties of materials are very important for designing of machines tools and structure. Mechanical properties must be taken into account and

Carbon equivalent (CE) & its affects on weldability?

Welding is a fundamental process in various industries, from construction to aerospace. The quality of welds is crucial to the structural integrity of a project. Carbon equivalent (CE) is a parameter that plays a significant role in determining the weldability of materials. In this article, we will explore what carbon equivalent is and how it

What is ASTM G48 testing. Explain?

In the world of materials science and engineering, corrosion is a persistent and costly problem. From the structural integrity of industrial components to the longevity of everyday consumer products, corrosion poses a significant threat. To combat this issue, rigorous testing methods have been developed to assess the corrosion resistance of materials. One such method is

ASTM A262 : Intergranular Corrosion Testing

IGC testing A262 Practice E refers to a standard test method used to evaluate the intergranular corrosion (IGC) resistance of stainless steel and high-alloy materials. This test method, described in Practice E of ASTM International standard A262, involves immersing specimens of the material in a solution of nitric acid and ferric nitrate.

What is Dilution and its effect in Welding Overlay?

Dilution is a term used in welding to describe the mixing of the base metal and filler metal during the welding process. In overlay welding, dilution refers to the extent to which the filler metal is mixed with the base metal.

Why Generally PWHT is not recommended for stainless steel?

Stainless steel is renowned for its exceptional corrosion resistance, making it a popular choice for various applications, including construction, food processing, and chemical industries. However, understanding the metallurgy of stainless steel, particularly in the context of welding and post-weld heat treatment (PWHT), is crucial. In this article, we will discuss why PWHT for stainless steel
