With the rapid development of the petrochemical industry, stainless steel materials have been widely used, which has also put forward higher requirements for the welding of pipes and plates. The pr...
1. The priority principle of arc welding with electrodes
For the installation and welding of pipelines whose diameter is not too large (such as below 610mm) and the length of the pipeline is not...
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...
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 so-called welding skills are simple welding methods, correct electrode angle and operation, and your welds will not be too bad.
At the beginning of welding, due to the lack of mastery of the we...
E71T-11 and E71T-GS both belong to AWS A5.20 carbon steel self-shielded flux-cored welding wire (FCAW-S). They do not require external shielding gas and are very suitable for outdoor or gasless e...
