SUREWELD SW-75
Sureweld SW-75 es un electrodo E7010-A1 celulósico, revestido para soldadura fuera de posición que produce depósitos de soldadura que conttttttienen 0.5% Mo.
Features
Sureweld SW-75 es un electrodo celulósico, revestido y multi - posiconal que produce un arco altamente penetrante. El depósito es capaz de producir uniones de soldadura de calidad rayos "x". La adición de molibdeno pemite su uso en acero altamente flexibles y de baja aleación. Los electrodos SW-75 son usados en tuberías cromo-moli o fundicion donde una gran fuerza tensora y resistencia al arrastre a alatas temperaturas y altas presiones son deseadas. Así mismo, algunas aplicaciones comunes han incluido dientes de engranes, dados forjados, reparación de ejes, boilers, bastidores de pozo petroléro y acoplamientos de cadena de aleación.

Extra Info
Procedure
- Horizontal and downhand welding require a medium to short arc with the electrode tilted 5° to 15° in the direction of travel. A slight oscillating motion is recommended for flat and horizontal position. Use a short whipping motion on vertical and overhead welds, allowing only enough time out of the crater for the metal to set up. Clean thoroughly between passes. When using in the vertical-down position, a stringer or weave technique should be incorporated. Amperages for vertical-down welding are similar to that of flat position welding
