Cleaning of pressure vessels before and after metal welding and design of associated workshops
Cleanliness of Pressure Vessels Before and After Metal Welding and the Related Factory Design
Metal welding is a mechanical method used to join two metal workpieces, and it is necessary to maintain the cleanliness of the welded parts before and after welding. In the process of designing a factory......
Measures to reduce hydrogen content in weld metal
Measures to Reduce Hydrogen Content in Weld Metal
Welding is a widely used method of joining materials. In addition to the cause of incorrect welding parameters or environmental problems, hydrogen is an important factor that affects the quality of welded joints. There are many sources of hydrogen......
Recommended values of welding voltage, wire feeding speed and base metal carbon content in electroslag welding
Introduction
Underbalanced Direct Current Resistance (DC) welding is a unique joining technique that utilizes electric current to locally heat a workpiece material. The electrical current is passed through the assembly, heating the surface of the material to its melting temperature. The component......
Pulse oxidizing gas shielded welding welding current range for vertical welding of steel
Pulse Oxidation Gas-Protected Arc Welding of Austenitic Stainless Steel
Austenitic stainless steel is an iron-based alloy consisting of chromium, nickel and other alloying elements. This type of steel is highly durable and corrosion-resistant, making it one of the most popular materials for use i......
The principle of short-circuit arc ignition method and the method of improving the success rate of arc ignition
Arc Initiating for Low Voltage Circuit Breakers:
Introduction
Low voltage circuit breakers are used to protect electrical systems and equipment from being overloaded or short circuited. The function of the breaker is to detect an over current, open the circuit, then to withstand and extinguish an ......
Microstructure Analysis of 45 Steel and W9MnCrV Friction Welded Joint
Microstructural Analysis of the Friction Stir Welding Joint of 45 Steel and W9MnCrV
Abstract
This paper presents the microstructural analysis of a Friction Stir Welding (FSW) joint between 45 steel and W9MnCrV. A Zirlag ZV50SP welding machine was used and a 20-round profile pin was used with a r......
Preventive Measures for Common Welding Defects
Prevention Measures for Common Defects in Welding
Welding is a process of joining two materials such as metals and plastics by the application of heat and pressure. Although welding can be a very efficient and cost-effective process, there are various risks and hazards related to it. Therefore, i......
Commonly used shielding gas for welding
Welding gas is an essential component of the welding process. It plays a critical role in providing a safe and consistent welding environment. The main purpose of a welding gas is to shield the weld zone from the atmosphere and protect the weld pool from oxidation and contamination. In this articl......
welding rod
Welding Rods
Welding rods are an essential component of the welding process. effective welding rods enable cohesive welder bonding between two separate pieces of metal or other conductive materials. A welding rod allows for the heat produced during the welding process to transfer between the two ......
