Features

Sureweld SW-75 is an all-position cellulosic coated electrode which provides a highly penetrating arc. The deposit is capable of producing X-ray quality welds. The addition of molybdenum allows for its use on high tensile, low alloy steels. SW-75 electrodes are used on chrome-moly piping or casting where high tensile strength and creep resistance at high temperatures and high pressures are desired. In addition, some common applications have included shaft build-up and repair, gear teeth, boilers, oil well casting, forging dies, and alloy chain links.

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
