What Is Beam Welding in London?
Beam welding is the process of joining steel beams and structural components using high-temperature welding techniques. This creates strong, permanent joints that allow beams to carry structural loads safely and transfer forces through a building frame.
Our beam welding service in London focuses on on-site welding of RSJs, universal beams, channels, columns, cleats, end plates and stiffeners. We follow engineer drawings and welding symbols, preparing the steel correctly before welding to ensure good penetration, alignment and finish on every weld.

Why Beam Welding Is Important for Structural Safety
Structural steel beams are often responsible for carrying major loads in a property. Poor or incomplete welding can compromise the integrity of the structure, causing deflection, cracking or even failure. Professional beam welding ensures that beams and steelwork perform as intended by the structural engineer.
Our beam welding London service focuses on delivering strong, consistent welds that align with drawings and specifications. Correct preparation, welding technique and inspection are essential to maintain the long-term safety and performance of your building, whether it’s a small extension or a large commercial project.
Correctly welded beams help ensure that openings, floors, roofs and frames stay stable and compliant with building regulations.
High-quality welding done right first time avoids costly re-work, delays and disputes with inspectors or building control later on.
Working with experienced beam welders gives builders, engineers and property owners confidence that the steelwork is safe and robust.
