Commitment to Excellence in Welding Solutions
Solo collaborates with local New Zealand authorities, international civil construction companies, and communities across the Asia Pacific to enhance infrastructure in Pacific Island nations. Our site welding teams are dedicated to providing reliable and durable solutions that contribute to the growth and development of these regions.
Our welding processes adhere strictly to ASNZS 4645.3.2018 standards, ensuring the longevity and reliability of our work. We maintain the highest standards of welding excellence, including ISO 21307:2017, which specifically addresses the butt fusion jointing of polyethylene (PE) pipes and fittings. This international standard guarantees that our welding practices meet rigorous quality and integrity requirements.
By complying with both ISO 21307:2017 and ASNZS 4645.3.2018, the Australian/New Zealand standard for on-site butt welding of polyethylene pipes, we ensure that our procedures not only meet local regulatory standards but also align with international best practices. This commitment assures the durability and reliability of every project we undertake.
Butt Welding




Solo Fusion Welding's butt-welding teams specialize in welding PE pipes of up to 2 meters in diameter, whether in trench or above-ground installations.
With extensive experience in assisting with PE pipe installations across New Zealand and the Asia Pacific, our teams excel at addressing site-specific challenges encountered in real-world scenarios. Collaborating closely with major civil engineering contractors, we ensure that all projects are executed efficiently and on schedule.

Electrofusion Welding




Electrofusion (E/F) welding is deceptively challenging. While acquiring a qualification in E/F welding may seem straightforward, achieving clean and precise welds, particularly in large diameters and in compliance with the ASNZS 4645.3.2018 standard, requires significant expertise.
Solo Fusion Welding tackles large and intricate electrofusion welds almost daily. Entrusting such critical tasks to inexperienced alternatives is a risk not worth taking. Choose Solo’s electrofusion pipe welders for reliable results you can trust.
Electrofusion welding often complements our custom fabrication or butt-welding teams. Recognizing that every application is unique, Solo’s expertise ensures the selection of the most suitable welding process for each project.

PE Extrusion Welding



In the modern day, there are very few companies that can weld PE Plastic. There are even fewer companies that have the skill set and the equipment to conduct on-site extrusion welding of heavy gauge PE Piping for the Civil Construction sector.
Our PE welding is completed in line with DVS 2208: Welding of thermoplastics – Extrusion welding of thermoplastics. DVS 2207-11: Welding of thermoplastics – Welding extruded sheets and films of thermoplastics.
Solo Fusion Welding stands out as one of the select few companies in the Asia Pacific region with the expertise required for this specialized work.
Consequently, our services are in high demand. Our highly skilled team is relied upon by the broader civil sector to ensure that projects are executed to the most exacting standards.

Site Installation




Timely, efficient, and cost-effective site installation is essential for the success of any civil infrastructure project.
With decades of experience, Solo Fusion Welding has established itself as a trusted partner to all major players in the New Zealand civil infrastructure industry.
We have cultivated strong relationships with a wide spectrum of stakeholders, ranging from local government authorities to structural engineers and machinery operators. These partnerships enable us to provide comprehensive support throughout every stage of your site project, up to completion.

Onsite Modifications




Solo Fusion Welding's versatility shines through in our capability to perform onsite modifications. We excel at adapting standard items to suit unique circumstances, ensuring seamless integration into your project.
Utilizing a combination of off-site and on-site fabrication, gaskets, electrofusion welding, and innovative problem-solving, we expertly install PE and PVC pipe, and fittings tailored to the specific requirements of your location or needs.
A common request involves modifying or “fitting out” water or chemical tanks. Solo possesses the rare ability to execute this work efficiently, even in tight or challenging locations, delivering quick and effective solutions.
