NOTES
| Note |
|---|
| Remove all damaged and foreign material by the air-carbon arc gouging process and grinding. Ensure all defective metal is removed. |
| In the event hairline cracks remain at flangeway depth, use a 1/8 in diameter E308 stainless electrode, to tie up these cracks and avoid hot cracking during the buildup process. |
| Use only light amounts and do not build-up with E308 stainless. It is for use in emergency situations where no other alternative is available to repair flangeway cracks. |
| As with all austenitic manganese welding products, interpass temperatures should be limited to 260°C (500°F) maximum. |
| A stringer bead, or at most, a slight weave is recommended to limit heat build-up. Excessive heat build-up causes manganese carbide precipitation that damages the toughness of austenitic manganese. |
