Welding Materials and Equipment in Kenya: What You Need to Know
Introduction
Welding is an essential trade in Kenya’s construction and fabrication sectors. From steel gate and grille fabrication to structural steel connections, roofing ridge welding, and metalwork repairs, welding is part of everyday construction and manufacturing activity.
Whether you’re a professional welder running a fabrication workshop, a contractor needing to weld structural connections on site, or a property owner commissioning security gates and grilles, understanding welding materials and equipment will help you make informed purchasing decisions.
Pioneer Hardware in Ruaka stocks a range of welding hardware items and equipment. This guide covers the essentials.
Common Welding Processes in Kenya
Arc Welding (SMAW — Shielded Metal Arc Welding)
By far the most common welding process in Kenya. Also known as “stick welding,” it uses a consumable electrode coated in flux. The flux creates a shielding gas during welding and forms a protective slag over the weld bead.
Advantages: – Simple equipment — just an arc welder, cables, and electrodes – Works on site, in the field, or in the workshop – Suitable for most mild steel construction applications – Equipment is affordable and widely available
Typical applications in Kenya: – Gate and grille fabrication – Structural steel connections – Steel frame construction – Pipeline welding (sewer and drain pipe joins) – General metalwork repairs
MIG/MAG Welding (GMAW — Gas Metal Arc Welding)
Uses a continuous wire electrode fed through a gun, with a shielding gas (CO2 or argon/CO2 mix). Produces clean, high-quality welds at high speed.
Advantages: – Fast and productive – Clean welds with less spatter – Can be used on thin materials
Limitations in Kenya: – Requires bottled gas (CO2 or argon mix) — less convenient on remote sites – Equipment more expensive than arc welders
TIG Welding (GTAW — Gas Tungsten Arc Welding)
Precision welding using a non-consumable tungsten electrode with argon shielding gas. Used for high-quality, precise welds on thin or sensitive materials.
Applications: Stainless steel and aluminium fabrication, decorative metalwork, precision engineering

Arc Welding Machines
Pioneer Hardware stocks arc welders suitable for various applications:
- Inverter arc welders (IGBT technology): Lightweight, energy-efficient, and suitable for most site and workshop use. Available in various output ranges from 100A to 250A+.
- Transformer arc welders: Traditional heavy-duty machines. More affordable but heavier and less energy-efficient.
Choosing the right amperage: – Up to 3mm thick steel: 80-120A – 3-6mm thick steel: 100-160A – 6-10mm thick steel: 150-200A+
Welding Cables and Connectors
– Electrode holder (stinger) — holds the welding rod
– Earth clamp — connects the work piece to the welding circuit
– Welding cables (4mm², 16mm², 25mm², 35mm²)
– Quick-connect/Dinse connectors
Welding Electrodes (Rods)
The welding electrode is the consumable that melts to form the weld metal. Common types:
E6013 (General Purpose)
The most widely used electrode in Kenya. Suitable for mild steel welding in all positions. Easy to strike and maintain arc, suitable for beginners.
– Applications: General fabrication, light structural work, gate and grille making
– Available sizes: 2.5mm (for thin material), 3.2mm (general use), 4.0mm (heavier sections)
E7018 (Low-Hydrogen)
Higher strength electrode for structural and pressure vessel applications. Requires dry storage conditions.
– Applications: Structural steel connections, high-strength joints
– Note: Must be stored in a rod oven to prevent moisture absorption
E6011 (All-Position)
Versatile electrode that can weld through rust and scale. Useful for repair work and outdoor applications.
Stainless Steel Electrodes
For welding stainless steel and dissimilar metals. More expensive but essential for food-grade and corrosion-resistant applications.
Welding Safety Equipment
Welding produces intense UV radiation, heat, sparks, and toxic fumes. Proper safety gear is non-negotiable:
Welding Mask/Helmet
– Fixed shade: Simple, affordable, shade 10-12 lens for arc welding
– Auto-darkening helmet: Automatically darkens when arc is struck — more convenient and safer for the welder
Welding Gloves
Thick leather gauntlet gloves that protect hands and forearms from heat, sparks, and UV radiation.
Welding Jacket or Apron
Leather or flame-resistant fabric jacket/apron to protect the body from spatter and heat.
Safety Boots
Steel-toed boots to protect feet from falling metal and sparks.
Welding Goggles
For grinding operations adjacent to welding — clear lens with side shields.
Welding Screen
Portable screen to protect bystanders from UV arc flash. Important in shared workshop or site environments.

Respirator / Fume Extraction
Welding fumes are hazardous. In enclosed spaces, use a welding respirator or provide forced ventilation/fume extraction.
Angle Grinders: The Welder’s Essential Tool
Every welder needs an angle grinder for:
- Cutting steel: Cutting wheels (1mm or 1.6mm thick)
- Grinding welds: Grinding wheels (6mm thick)
- Cleaning and surface preparation: Flap discs and wire cup brushes
- Deburring and chamfering: For preparing weld joints
Available at Pioneer Hardware: – 115mm (4½”) angle grinders — for light cutting and grinding – 230mm (9″) angle grinders — for heavier cutting on site – Cutting discs (metal and stone) – Grinding wheels – Flap discs (various grits) – Wire cup and disc brushes
Steel Materials for Fabrication
Welding requires steel — here are the common steel sections available at Pioneer Hardware:
Mild Steel Square Hollow Sections (SHS)
Used for gate frames, grilles, furniture frames, and structural columns:
– 20×20mm, 25×25mm, 40×40mm, 50×50mm, 75×75mm
Mild Steel Rectangular Hollow Sections (RHS)
For gate frames, beams, and structural applications:
– 25×50mm, 40×80mm, 50×100mm, 60×120mm
Mild Steel Round Hollow Sections (CHS)
For railings, handrails, and decorative work.
Mild Steel Flat Bar
For bracing, brackets, and decorative metalwork.
