Is ASTM A234 WP1 The Same Material As WPB?
No, Different Alloy Family
WPB is a plain carbon steel; WP1 carries a deliberate molybdenum addition
Higher Temperature Ceiling
Molybdenum resists graphitisation, letting WP1 run hotter than WPB safely
Lower Tensile Floor
WP1 tensile minimum sits lower than WPB, trading raw strength for stability

Welding Precautions For SA234 WP1 Lap Joint Stub Ends
Preheat The Joint
Apply controlled preheat to reduce hydrogen-cracking risk in thicker sections.
Use Matching Filler
Select a Cr-Mo compatible electrode or wire for the WP1 chemistry.
Control Interpass Temperature
Keep interpass within the qualified WPS band throughout the weld.
Plan For PWHT
Schedule post-weld heat treatment where the code or thickness requires it.
Protect The Lap Face
Keep the stub end’s flange-contact face free of weld spatter.
Inspect Before Closure
Run visual and dye-penetrant checks ahead of the final hydrotest.
Not Sure Which Fitting Type Fits Your Line?Share pressure, temperature & end preparation – we’ll recommend the type.
