The coating plays a complex metallurgical reaction and physical and chemical changes in the welding process, which basically overcomes the problems in the welding of the photo electrode, so the coa...
Welding material standards are an important basis for ensuring welding quality and safety. Different countries or regions have formulated corresponding standards according to their own industrial n...
Spot welding is a resistance welding method in which the weldment is assembled into a lap joint and pressed between two electrodes, and the base metal is melted by resistance heat to form a solder ...
SMAW, also be well known as electrode arc welding, is a fusion welding method in which the arc is induced by the electrode and the welding parts are melted by the arc heat. It is the most widely us...
1. Reduce stress concentration The stress concentration point of the fatigue crack source on the welded joint and structure, and all means of eliminating or reducing stress concentration can improv...
First, Welding cracks and pores are generated.
The moisture absorbed by the welding rod becomes gas under the action of the welding arc heat, which decomposes hydrogen, resulting in the formation ...
