Abstract: Pressure vessels play a crucial role in the industrial sector, and welding is a key process involved. Copper welding wire, as a commonly used welding material, finds extensive application in pressure vessel welding. This article aims to discuss the quality management, storage, and testing techniques for copper welding wire in pressure vessel welding, with…
In industrial production, laser welding technology has become an indispensable tool. Among them, handheld laser welding technology is widely used in various industries due to its high efficiency and flexibility. But how does the performance of handheld laser welding hold up under high-temperature conditions? This is a question we need to explore. Under high-temperature conditions,…
Gas Tungsten Arc Welding (GTAW), also known as TIG welding, in the downward position, is a high-quality welding method commonly used for welding materials such as stainless steel, aluminum, magnesium, and copper. Here are the steps for performing TIG welding in the downward position: Preparation: Before welding, it is necessary to ensure that the welding…
Underwater copper alloy welding material is a special welding material that is widely used in marine engineering and shipbuilding. In the marine environment, copper alloy welding materials have excellent corrosion resistance and water pressure resistance, which can effectively prevent corrosion and damage to welding joints by the marine environment. The main components of copper alloy…
Types of copper soldering materials Copper soldering materials can be divided into two categories: soft soldering and hard soldering. Soft soldering is mainly used for low-temperature (below 500°C) and low-strength soldering, including silver soldering and brazing materials. Hard soldering is used for high-temperature (above 500°C) and high-strength soldering, mainly including copper solder wire and copper…
The reasons for the porosity in the welding with pressure openings are as follows During the construction of engineering welding with pressure openings, the bubbles in the weld pool of the pipeline failed to escape during solidification, and the holes formed in the weld metal of the pipeline (or the surface) are called pores. It…
Abstract: The properties and components of welding shielding gases have a great impact on welding quality. Different properties of common welding shielding gases have different effects on welding speed, weld penetration and arc stability. Therefore, in the actual production process, a variety of influencing factors should be considered comprehensively to select appropriate shielding gases to…
Monel is a nickel-copper Alloy that comes in two grades, Monel 400 and K-500, which generally refer to Alloy 400. Alloy 400, with its excellent resistance to neutral and basic salts, has long been standard in salt-making systems. It is one of the few materials that can come into contact with fluorine, hydrofluoric acid, and…
Basic knowledge of flux cored wire arc welding What is flux-cored arc welding? Flux-cored arc welding (FCAW) is a welding method that uses the arc between flux-cored wire and workpiece to heat. Under the action of arc heat, welding wire metal and workpiece are fused to form a molten pool, and after the arc moves…
Cause of occurrence ① Uneven wire feeding ② Conductive mouth is not suitable for slipping, whether the friction resistance of the guide tube is too large ③ The primary input voltage changes greatly Check items and their elimination methods ① Whether the welding wire pan rotates smoothly, whether the wire feeding wheel slides, and whether…
