What information is typically listed in the weld passes table of a WPS?

• A. Technique (weave or string), electrode size, amperage, voltage, and travel speed
• B. Shielding gas type only
• C. Base metal chemical composition
• D. Post weld heat treatment temperatures

Answer: (A)

The weld passes table captures the per-pass welding parameters that control how each pass in a multi-pass weld is executed. This is where the specific settings that directly determine heat input and bead characteristics for every pass live. The technique, such as weave or string, tells the welder how the arc is moved to shape the bead and ensure proper coverage and fusion. Electrode size affects the current-carrying capacity and how wide or thick the deposit will be, so it belongs in the per-pass specification. Amperage and voltage set the arc heat and stability, influencing penetration, fusion, and bead appearance, so each pass can have its own target values. Travel speed controls how quickly the weld is laid down, which directly alters heat input and deposition rate for that pass. Together, these details ensure each pass contributes correctly to the joint design and overall weld quality. Other options don’t fit because shielding gas type alone doesn’t define per-pass behavior, base metal chemistry sets material properties but isn’t a per-pass deposition setting, and post-weld heat treatment temperatures are applied after welding rather than describing how each pass is performed.
