Welding Wire China  effect refers to the solder layer hardness, wear-resistant and heat-resistant properties, the performance level of the following factors:
1. Welding Rod  current size, the length of the arc. The current is large, the length of the arc, alloying elements easy burnout, Conversely, the beneficial alloying elements transition.
2. Preheat temperature, slow cooling conditions to determine the quality of the surfacing layer.
Some surfacing metal with different heat treatment methods can be different hardness.
Hardness and chemical composition of the surfacing layer refers to the surfacing metal surfacing of more than three.

What type stainless There are basic coated stainless steel electrode and Aluminum Flux Core Welding Wire acidic drug skin two categories. Basic coated stainless steel electrode with a type of stomatal sensitivity to small , stable alloy composition Fixed and excellent mechanical properties and welding performance characteristics ; acidic Drug skin type stainless steel electrode with drug-resistant skin redness and excellent mechanical properties and welding performance. ( 1 ) stainless steel electrode model based GB/T983-1995 " stainless steel electrode " requirement , stainless steel electrodes deposited metal model based on the chemicalChemical composition , drug skin type , welding position and the welding current category from Points. Its model preparation method is: the first letter "E" indicates electrode , "E" behind the numbers indicate the chemical composition of deposited metal classification code , such asThere are special requirements for chemical composition, the chemical composition of elemental symbol table Shown , on the back of digital ; dash " - " followed by two numbers indicate the drug skin type , welding position and the welding current category.
