From prototype to full-scale production, 3SI offers precision welding services to meet our customers’ exact specifications.
Through the use of state-of-the-art equipment, we offer precision arc and metal inert gas (MIG) welding services across a variety of industries, including agricultural, mining, aerospace, construction and Energy, among many others.
Each of our highly skilled personnel are AWS-certified to D1.1, D1.6, D9.1, and D10.9 standards, and our expertise includes a number of welding methods:
Our precision arc and MIG welding services are suitable for a vast array of metals, including carbon steel, stainless steel, Hardox wearplate, Strenx, as well as other alloys.
For high-precision and large-scale projects, we offer fully automated and CNC-controlled welding services, capable of handling virtually any customer specification while maintaining the tightest tolerances available in the industry.
In addition to welding, we offer a number of custom metal fabrication and secondary services, which thereby allows us to complete even the most complex projects under one roof. Our value-added services include machining, mechanical assembly, kitting, packaging, painting and galvanizing, among others. Our breadth of services allows us to provide customers with competitive prices, reduced lead times, and peace of mind that their project is in the right hands.
Additionally, customers can rest assured, knowing the quality is never a question with 3SI. As an ISO 9001/2015 certified manufacturer, we offer an array of inspection procedures and a number of testing processes, including die penetrant and non-destructive testing (NDT), along with dimensional inspections using calibrated measuring equipment.
