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 -
Why does the machine tool collide with the tool
The matter of a machine tool collision is not a small matter, but it is also a big one. Once a machine tool collision occurs, a tool worth hundreds of thousands of yuan may become waste in an instant. Don't say I am exaggerating, this is a real thing. ...Read more -
The precision requirements of each process of CNC machining center are worth collecting
Precision is used to indicate the fineness of the workpiece product. It is a special term for evaluating the geometric parameters of the machining surface and an important indicator for measuring the performance of CNC machining centers. Generally speaking, machining acc...Read more -
The Difference Between Surface Finish and Surface Roughness
First of all, surface finish and surface roughness are the same concept, and surface finish is another name for surface roughness. Surface finish is proposed according to the visual point of view of people, while surface roughness is proposed according to the actual micr...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 -
