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.
