Ship and Marine Building
There are many types of welding rods used in shipbuilding, which are determined by the various systems of the ship itself. Welding rods that may be used include stainless steel welding rods (for stainless steel facilities) and others, as follows: Nickel and nickel alloy welding materials are widely used in offshore drilling platforms, land-based or ship-borne gas turbines, high-temperature combustion chambers of various aerospace and aerospace engines, and nuclear power plants. , related equipment for thermal power plants, new automobile exhaust systems, military weapons and equipment, petroleum refining and various chemical equipment, etc.
Manual welding rod
Downward vertical welding electrode: Compared with vertical upward welding, the efficiency is increased by 1 to 2 times Iron powder welding rod: The deposition efficiency can be increased by 130%~240%, and the production efficiency can be increased by more than 50%.
Gas shielded solid welding wire
There are too few varieties of gas shielded solid welding wires in my country (E49-1, ER70S-6). We should vigorously expand varieties in the future. At the same time, the process performance of solid welding wire is further improved, spatter is reduced, and the shape is beautiful. For example, the developed active solid welding wire has been surface-activated and has anti-rust and lubrication functions.
Gas-shielded flux-cored welding wire
From the perspective of development trends, flux-cored welding wire will be the main welding material for shipbuilding enterprises in the 21st century, and the current application rate has reached more than 60%. It is characterized by beautiful weld bead formation, stable arc, small welding spatter, good all-position welding process performance, fast welding deposition speed, and high production efficiency.
