Description: A102 is a titanium calcium type coating Cr19Ni10 stainless steel electrode. Deposited metal has good mechanical properties and resistance to intergranular corrosion. Has excellent welding performance and anti-hole performance, drug-resistant skin redness, resistance to cracking. AC and DC. Uses: 0Cr19Ni9 for welding temperature below 300 ℃ corrosion resistant stainless steel construction and 0Cr19Ni11Ti of. Mechanical properties of the deposited metal pilot project Rm (MPa) ≥550 A (%) ≥35 reference current (AC, DC +) electrode diameter (mm) φ2.0 φ2.5 φ3.2 φ4.0 φ5.0 Welding current (A ) 40 to 80 50 to 10 070 to 130 100 to 160 140 to 200 stainless steel welded note 1, usually stainless steel electrode with titanium calcium type and low hydrogen type two. Welding current DC power supply as much as possible, help to overcome redness and melting depth electrodes. Titanium calcium type of electrode is not suitable for all position welding, suitable only for peaceful fillet weld flat; low hydrogen type coating electrodes do all position welding. 2, stainless steel welding rod should be used in the dry. To prevent cracks, pits, holes and other defects, before welding titanium calcium type by 150-250 ℃ drying 1h, before the low hydrogen type welding by 200-300 ℃ drying 1h. Not repeated drying, otherwise drug skin shedding. 3, weld clean while preventing electrode coated with oil and other dirt, to avoid increasing the carbon content of the weld and affect the quality of welding. 4, in order to prevent heating and intergranular corrosion, welding current is not too large, generally should be lower than about 20% carbon steel electrode, the arc is not too long, fast cooling between layers to narrow channel bonding is appropriate. 5, when the arc note that not arc in the non-welded parts, weldments best selection and the same material arc plate arc. 6, should be adopted in short arc welding, arc generally 2-3mm, long prone to hot cracking arc. 7, transportation bar: with short, quick arc welding, generally does not allow lateral oscillation, which aims to reduce the heat and the heat-affected zone width, improve inter-weld resistance to intergranular corrosion and reduce the tendency of hot cracking. 8, welding dissimilar steel welding rod should be carefully selected to prevent the improper selection of hot cracking welding or heat after heat treatment causes precipitation of σ phase, the metal embrittlement.
