Welding
Welding joins metal parts by melting and fusing them, with or without filler metal, to make strong permanent joints. We arrange TIG, MIG, arc and spot welding for steel, stainless steel and aluminium, from small precision assemblies to heavy structures.
What it is
The welding process is chosen by material, thickness, joint and quality needed: TIG for thin and critical stainless or aluminium joints, MIG for productive welding of thicker steel, manual metal arc (stick) for site and heavy work, and resistance spot welding for sheet overlap joints.
Good welding depends on joint preparation, fit-up, correct parameters and skilled welders, followed by inspection appropriate to the application.
Typical applications
- Fabricated frames and assemblies
- Stainless steel food and pharma equipment
- Aluminium structures and tanks
- Pressure parts and pipework (qualified procedures)
- Repair welding
Suitable materials
- Mild and structural steel
- Stainless steel
- Aluminium
- Alloy steels (with procedures)
Points to consider
- Show weld symbols with type, size and length on drawings.
- Specify inspection level and any procedure/welder qualification needs.
- Stainless welds may need pickling and passivation afterwards.
- Distortion is controlled by sequence and fixturing; allow machining after welding for precision.
Frequently asked questions
Which welding process is best?
TIG for thin or high-quality stainless and aluminium joints, MIG for fast welding of thicker steel, stick for heavy and site work, and spot welding for sheet overlaps.
Can you weld aluminium?
Yes, typically by TIG or MIG with suitable filler and skilled welders.
Do welded parts need testing?
It depends on use. Visual inspection is standard; DP, MPI, UT or radiography are arranged for critical joints when specified.
