When discussing WPS (Welding Procedure Specification) for handrails, it typically refers

to the standardized procedures for welding metal handrails to ensure they are structurally
sound and meet safety standards.

A Welding Procedure Specification (WPS) includes several components, such as:

1. Base Materials:
o Handrails can be made of different metals like stainless steel, mild steel, or
aluminum, and the WPS will specify the material type, grade, and thickness.
2. Welding Process:
o Common welding processes used for handrails include MIG (Metal Inert
Gas), TIG (Tungsten Inert Gas), and Stick welding. The procedure will
indicate which method is used based on the material and desired finish.
3. Electrode or Filler Material:
o The WPS will specify the electrode type, such as E7018, for steel welding, or
ER308L for stainless steel. The electrode is chosen based on the base material
being welded.
4. Preheat and Post-weld Heat Treatment:
o The WPS will define any necessary preheating or post-weld heat treatment
required to avoid cracking, distortion, or weakness in the welded areas,
especially if you're working with materials prone to stress.
5. Welding Parameters:
o The WPS will provide critical parameters, including:
 Voltage and amperage settings.
 Travel speed for welding.
 Shielding gas type (e.g., argon, CO2) and flow rate.
 Weld position (e.g., flat, horizontal, vertical, or overhead).
6. Joint Design:
o The WPS will describe the joint design for the handrail welding, such as butt
joints, fillet welds, or corner joints. The strength of the weld is largely
determined by the type of joint and the welding process.
7. Inspection and Testing:
o A WPS should include procedures for weld inspection, whether it's visual
inspection or more detailed techniques like X-ray, ultrasonic testing, or
magnetic particle testing to ensure weld integrity.
o Handrails often require compliance with safety standards such as OSHA or
local building codes.
8. Safety Precautions:
o Proper ventilation, protective gear (like gloves, face shields, etc.), and
adherence to safety protocols while welding will be outlined in the procedure.

If you're looking for a WPS specifically designed for handrail welding, it might be best to
consult with a professional welder or a welding engineer who can tailor the procedure to your
materials and needs.

Would you need more specifics on any of these aspects for your project?
