During fusion welding, under the action of the welding heat source, the liquid metal part with a certain geometric shape formed on the weldment by the molten electrode metal and the partially molte...
Introduction
As the vehicle body is the carrier of other parts of the vehicle, its manufacturing technology directly determines the overall manufacturing quality of the vehicle. Welding is an impor...
Harmful factors of welding materials
(1) The main research object of welding labor hygiene is fusion welding, and among them, the labor hygiene problems of open arc welding are the biggest, and th...
Electrode arc welding is the most widely used welding method in industrial production. The metal to be welded is one pole, and the electrode is the other pole. When the two poles are close to each ...
The welding electrode is a metal rod that is melted and filled at the joint of the welding work-piece during gas welding or electric welding. The material of the electrode is usually the same as th...
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...
