Size: diameter 4.0 mm, length 400 mm, weight 1 kg. Low sodium hydrogen welding electrode with carbon steel core Model: D999 High hardness ≥85, abrasion and shock resistant. Dual use AC and DC With tungsten carbide and a low hydrogen sodium coating as the main ingredients. Can be used in AC and CC and can be used for coating and welding all carbon steel base materials. The sweat layer has an extremely high hardness and resistance to external impacts. Efficiency to resist strong friction of mud. and stone. Application for welding mechanical parts with high wear resistance such as lighters (new stapler, stirrer, counter cylinder, coal cutting, hammer), cement (life plate, grinding plate), yes, stone grinder, mining machines, concrete mixing blades, bulldozers and pump blades, draping, nurses high-speed sand xage, etc. › See more product details; Product description Precautions: 1. Before welding, it is necessary to remove impurities such as rust and welding oil. Such heavy welding parts must be heated and stored. 2. How to avoid burning: try using short circuit and arc sweat to avoid burns of alloy elements. 3. Multi-layer coating: the metal content of the coating is extremely high. It may be a multi-layer coating, usually 1 to 3 layers of coating. 4. IMPROVE SHOCK RESISTANT: multi-layer surfing, heat can be soldered once, preferably with hot limescale, and its wear resistance remains unchanged, which improves impact resistance. 5. How to avoid the case of the case: it can first be soldered at the place where the original welding layer is sanded, and it is better to solder the welded piece gradually to prevent the original welding layer from heating quickly. Excretion by rapid cooling. 6. How to avoid the formation of air holes: when the welding rod is damp, the welding layer will have local pores to allow the electrode to dry, we recommend using at 500°C for 1-2 hours.; Product description Precautions: 1.
