There are some inherent problems in dissimilar metal welding that hinder its development, such as the composition and performance of the dissimilar metal fusion zone. Most of the damage to the diss...
TIG spot welding (also known as gas tungsten arc spot welding) is a specialized technique that uses a tungsten electrode to generate an arc that melts a localized area of overlapping metal sheets,...
The welding residual stress is caused by the uneven temperature distribution of the weldment caused by welding, the thermal expansion and contraction of the weld metal, etc., so the welding constru...
Knowledge point 1: Influencing factors and countermeasures of welding process quality
Process quality refers to the degree of guarantee of product quality in the process of production. In other wor...
Flux-cored welding wire first appeared in the United States and Germany in the 1920s. However, it was not until the 1950s that it was really widely used in industrial production, especially after t...
Single-sided welding with double-sided formation is a core technique that welders must master, and it is particularly critical in the welding of pressure vessels and pipelines. It requires the wel...
