Take you closer to plasma arc welding
Introduction Plasma arc welding refers to a fusion welding method that uses a high-energy-density plasma arc beam as a welding heat source. Plasma arc welding has the characteristics of concentrated energy, high productivity, fast welding speed...Read more -
Do you know the rolling welding process
1. Overview Roll welding is a type of resistance welding. It is a welding method in which the workpieces are assembled to form a lap joint or butt joint, and then placed between two roller electrodes. The roller electrodes press the weldment an...Read more -
Welding tips Precautions for galvanized pipe welding
Galvanized steel is generally a layer of zinc coated on the outside of low-carbon steel, and the zinc coating is generally 20μm thick. The melting point of zinc is 419°C and the boiling point is about 908°C. The weld must be polished before welding The galvanized layer a...Read more -
Tips How to distinguish welding slag and molten iron during welding
During the welding process, welders can see a layer of covering material floating on the surface of the molten pool, which is commonly known as welding slag. How to distinguish welding slag from molten iron is very important for beginners. I think it should be distinguis...Read more -
Note that not all post weld heat treatments are beneficial
Welding residual stress is caused by the uneven temperature distribution of welds caused by welding, thermal expansion and contraction of weld metal, etc., so residual stress will inevitably be generated during welding construction. The most common method to eliminate re...Read more -
The selection and use of flux really plays a big role
Description Flux: A chemical substance that can help and promote the welding process, and has a protective effect and prevents oxidation reactions. Flux can be divided into solid, liquid and gas. It mainly includes "assisting heat conduction", ...Read more -
Have you heard about the efficient hot wire TIG welding process
1. Background Abstract The requirements for pipeline prefabrication in the offshore engineering and petrochemical industries are relatively high, and the amount of work is relatively large. The traditional TIG welding manual base and MIG weldin...Read more -
Aluminum alloy welding is difficult – the following strategies can help you solve it
Aluminum alloy welding is very different from the welding of general carbon steel, stainless steel and other materials. It is easy to produce many defects that other materials do not have, and targeted measures need to be taken to avoid them. Let's take a look at the pro...Read more -
The form of arc welding droplet excess
According to the welding parameters from small to large, they are: short-circuit transition, droplet transition, spray transition 1. Short-circuit transition The molten droplet at the end of the electrode (or wire) is in short-circuit contact with the molten pool. Due t...Read more -
Six advanced welding process technologies that welders must know
1. Laser welding Laser welding: Laser radiation heats the surface to be processed, and the surface heat diffuses to the inside through heat conduction. By controlling laser parameters such as laser pulse width, energy, peak power and repetition frequency, the workpiece ...Read more -
Manual Tungsten Inert Gas Arc Welding of Stainless Steel Sheets
【Abstract】Tungsten inert gas welding is a very important welding method in modern industrial manufacturing. This paper analyzes the stress of the stainless steel sheet welding pool and the welding deformation of the thin plate, and introduces the welding process esse...Read more -
