What is Welding Defects – Types, Causes and Remedies?

What are Welding Defects? Welding Defects can be defined as the irregularities formed in the given weld metal due to wrong welding process or incorrect welding patterns, etc. The defect may differ from the desired weld bead shape, size, and intended quality. Welding defects may occur either outside or inside the weld metal. Some of …

How Shielded Metal Arc Welding (SMAW) Works?

Shielded Metal Arc Welding (SMAW) is also called Manual Metal Arc Welding (MMAW) or flux shielded arc welding or popularly known as stick welding. In SMAW we generally use consumable types of electrodes. Consumable electrode means flux covered on the rod. Because of flexibility and simplicity, SMAW is the world’s best welding process. It is …

What Are Different Types of Welding? – Complete Guide

Welding is the process of joining of two or more pieces of materials especially metals with the help of heat and pressure. Before the 19th century, there was mainly one type of welding that is forge welding which was mostly preferred by blacksmiths after arc welding and oxy-fuel welding. But due to eye-watching progress in …

What is Friction Stir Welding? – Best Explanation

Introduction: Friction stir welding (FSW) is a solid-state joining process. Solid-state welding means that there is no molten state included in joining or welding the workpiece. This joining technique saves energy and is eco-friendly. It is mostly used to weld aluminum materials in the automobile and aerospace industries. The FSW is the process in which …

What is Friction Welding Process and How it Works?

Friction Welding (FRW) is a solid-state welding process which means that in this process heat is not provided from outside the system and no molten state of metal is present in this process. In this welding, process heat is generated by mechanically induced friction by sliding a workpiece on another part of it. After some …
