If you want to do argon arc welding well, you must remember these process taboos!
Taboos of Tungsten Inert Gas Arc Welding Process 1 Avoid using DC reverse welding in general welding During DC tungsten inert gas arc welding, the heat generated by the anode is much greater than that of the cathode. Therefore, when using DC positive connection (workpiece positive connection) we...Read more -
Analysis of the causes of incomplete welding of branch pipe platform and its countermeasures
1 Introduction With the development of the oil and gas industry, the market has placed higher and higher demands on the exhaust pressure of natural gas compressors. In addition to high quality requirements for the main components of the compressor, higher and higher requirements are placed on th...Read more -
How many people can master the performance of welding heat affected zone?
The welding heat affected zone (HAZ) is different from the weld. The weld can be adjusted by chemical composition, redistribution and appropriate welding process to ensure the performance requirements, while the performance of the heat affected zone cannot be adjusted by chemical composition. It ...Read more -

Oxygen Generator (Pressure Swing Adsorption)
Principle: The pressure swing adsorption (PSA) oxygen production device uses clean compressed air as raw material and high-quality zeolite molecular sieve as adsorbent to produce oxygen from the air under a certain pressure. The purified and dried compressed air is pressurized and adsorbed in th...Read more -
Why do steel parts need to be quenched and tempered? What are the effects?
Tempering treatment: The heat treatment method of high temperature tempering after quenching is called tempering treatment. High temperature tempering refers to tempering between 500-650℃. Tempering can adjust the performance and material of steel to a great extent. Its strength, plasticity and t...Read more -
What are the advantages and disadvantages of hard rails and linear rails for CNC machine tools? Finally explained!
What I have learned so far is this: if the general machining center is used to make products, then buy linear rails. If it is used to process molds, then buy hard rails. The precision of linear rails is higher than that of hard rails, but hard rails are stronger and more durable. Today th...Read more -
A simple way to identify 304 and 201 stainless steel plates
304 stainless steel is often used as the inner layer (i.e. directly in contact with water) due to its excellent corrosion resistance. 201 stainless steel cannot be used as the inner layer due to its poor corrosion resistance, and is often used as the outer layer of the insulation water tank. How...Read more -
