Welding Procedure EPI-11-WP6 Rev. 1
Page 2 of 3
6. PREHEATING, INTERPASS TEMPERATURE & CONTROLLED COOLING
a) A minimum preheat temperature of 120°C (250°F) shall be applied to an area of at least 150 mm (6 in.) from any point to the area to be repaired. Note: The entire girth weld will be preheated to 38°C (100°F) prior to grinding repair and maintained once welding starts until repair completion.
If the interpass temperature falls below the minimum preheat temperature, the entire weld joint shall be heated to the minimum preheat temperature prior to starting the next weld pass.
The maximum interpass temperature shall not exceed 204°C (400°F).
Preheating may be applied by oxy-fuel torch, propane torch, electrical induction coils or any other method approved by Enbridge.
Preheat temperature shall be checked using temperature indicating crayons, thermocouple pyrometers or other suitable method approved by Enbridge to determine that the required preheat temperature is obtained prior to, and maintained during the welding operation.
Where applicable, precautions shall be taken through the use of insulating covers or other means to control the cooling rate of the weld after any pass.
7. POST WELD HEAT TREATMENT
Welds prepared in accordance with this specification shall not be subjected to post-weld heat treatment.
8. ELECTRICAL CHARACTERISTICS
a) Current Type: Direct Current, Reverse Polarity (DCRP) b) Amperage, Voltage and Travel Speed: See TABLE # 1 c) Heat Input: See TABLE # 1
9. TECHNIQUE
a) Minimum number of root & hot pass welders: One b) Stringer or Weave Bead:
Root & Hot Pass: String; Fill & Cap Pass: String or Weave
• Number of Weld Layers: Four weld layers minimum.
c) Cleaning methods: Hand or power tools may be used. Each pass shall be thoroughly cleaned and free of slag and scale prior to depositing the next weld layer. The completed weld shall be brushed and free of spatter.
d) Filler and Finish Beads and Finish to be Achieved: Weld repairs shall be completed in a full operation without stopping. The completed welds shall have a substantially uniform cross-section for it’s entire circumference. The crown of the weld shall not be below the surface of the adjacent base material.
10. REMOVAL AND REPAIR OF DEFECTS
Repairable defects shall be removed by grinding. The minimum length of any repair shall be 50.8 mm (2.0 in.). Welding shall be performed following the details outlines in this specification.
