Certified Welding for Every Application
Alliance Metal Solutions provides professional welding services across three core processes: MIG (GMAW), TIG (GTAW) and fibre laser welding. Our qualified welders and modern equipment handle everything from heavy structural connections to fine cosmetic joins on visible surfaces, delivering the strength and appearance your project demands.
All structural welding at our Somersby facility is performed in accordance with AS/NZS 1554, the Australian standard for structural steel welding. Our welders hold current qualifications and work to documented weld procedure specifications (WPS) that define every parameter, from wire type and shielding gas to travel speed and interpass temperature. This disciplined approach ensures consistent, compliant welds across every job.
For applications where weld appearance matters, such as architectural metalwork, furniture, shopfittings and consumer products, our TIG welding capability delivers clean, precise beads with minimal spatter and discolouration. We TIG weld stainless steel, aluminium and mild steel to a high cosmetic standard, reducing the need for post-weld grinding and finishing.

Welding Processes and Expertise
MIG welding is our workhorse process for general fabrication, offering high deposition rates and strong, reliable welds on mild steel and stainless steel assemblies. It is well suited to structural steelwork, frames, brackets, tanks and general weldments where speed and penetration are priorities. Our MIG welding stations are equipped with synergic power sources that automatically optimise wire feed speed and voltage for the selected material and thickness.
TIG welding provides superior control for thin materials, dissimilar metal joints and applications where weld appearance is critical. We use TIG for stainless steel food-grade equipment, aluminium components, architectural features and any application where a smooth, oxide-free weld bead is required. Pulse TIG settings allow us to minimise heat input on thin sections, reducing distortion and maintaining material properties in the heat-affected zone.
Fibre laser welding is our newest capability, offering extremely focused heat input with minimal distortion. It is particularly effective for joining thin-gauge materials and for applications that demand a narrow, consistent weld seam. The reduced heat-affected zone preserves the parent material properties and produces a weld that often requires no post-processing at all.
Regardless of the process used, every welded assembly undergoes visual inspection as standard. For critical applications, we arrange non-destructive testing (NDT) including dye penetrant, magnetic particle and ultrasonic inspection through accredited third-party providers. All inspection results are documented and supplied with the finished product.
Frequently Asked Questions
What welding certifications do your welders hold?
Our welders hold qualifications in accordance with AS/NZS 1554.1 (structural steel welding) and AS/NZS 1554.6 (stainless steel welding). Individual welder qualification records are maintained and renewed on schedule. We can provide copies of relevant qualifications as part of the project documentation package when required.
Can you weld aluminium and stainless steel?
Yes. We TIG and MIG weld aluminium alloys including 5052, 5083, 6061 and 6082, as well as stainless steel grades 304, 316 and duplex. Each material requires specific filler metals, shielding gases and technique, and our welders are trained and qualified for each combination we offer.
Do you offer weld inspection and testing?
Visual weld inspection is carried out on every job as standard practice. For projects that require formal non-destructive testing, we coordinate dye penetrant inspection (DPI), magnetic particle inspection (MPI) and ultrasonic testing (UT) through accredited third-party laboratories. Test reports and weld maps are supplied as part of the quality documentation.
