Our system uses welded frames + bolted connections for optimal performance
Welding provides a stronger and more integrated structure, while bolted connections offer flexibility, easy assembly, and replaceability. The best choice depends on whether the system requires permanent strength or modular adaptability.
In aluminum systems like:
scaffolding
truss
stage platforms
connections are not a detail.
They define the structure itself.
Two systems using the same material can perform completely differently depending on:
welding quality
connection method
structural design
A welded connection joins metal parts permanently using heat.
Characteristics:
no movable joints
continuous structure
high rigidity
Used in:
aluminum truss systems
stage frames
scaffolding frames
Welding quality explanation:
Welding Quality Guide for Aluminum Structures
A bolted connection uses mechanical fasteners to join parts.
Characteristics:
removable joints
adjustable structure
modular assembly
Used in:
scaffold assembly
truss connection systems
modular stage platforms
Factor | Welding | Bolted Connection |
|---|---|---|
Strength | High (continuous structure) | Medium–High (depends on design) |
Flexibility | Low | High |
Assembly | Permanent | Removable |
Maintenance | Difficult | Easy |
Transport | Fixed shape | Easy to disassemble |
Application | Structural frame | Modular systems |
Welding creates a continuous load path.
This means:
better force distribution
fewer weak points
higher rigidity
However:
heat affects material strength
poor welding can weaken structure
See material effect:
6061-T6 vs 6082-T6 Aluminum
Bolted systems are designed for:
repeated assembly
transportation
adjustable configuration
This is critical in systems like:
aluminum scaffolding
modular stage platforms
Selection reference:
How to Choose Aluminum Scaffolding
requires factory production
not adjustable on site
strong but fixed
easy to assemble
requires basic tools
faster for on-site work
Installation logic:
Installation Methodology for Modular Systems
Both systems can be safe if designed correctly.
But risks differ:
poor weld quality
hidden cracks
heat-affected weakness
loose bolts
incorrect installation
wear over time
Safety reference:
Safety Standards and Engineering Constraints
frames → welded
connections → bolted
This combination provides:
structural strength
modular flexibility
main structure → welded
connection nodes → bolted (spigot or bolt system)

What is Lighting Truss?
frame → welded
platform connection → bolted
Load logic:
Stage Platform Load Calculation
Use welding when:
permanent structure is required
high rigidity is needed
minimal movement expected
Use bolted connection when:
system must be modular
frequent assembly/disassembly is needed
transportation is required
In real engineering:
The best solution is not choosing one
It is combining both
Typical structure:
welded frames (strength)
bolted connections (flexibility)
This is the standard in:
scaffolding
truss systems
stage platforms
Yes, in terms of structural continuity, but only if welding quality is high.
Yes, when properly installed and maintained.
To balance strength and flexibility in modular systems.
A combination of welded frames and bolted connections.
Welding and bolted connections are not competitors.
They serve different purposes.
Welding provides strength
Bolting provides flexibility
The best systems combine both to achieve:
safety
efficiency
adaptability
