AWS & ASME Certified GTAW and GMAW Welding

The foundation for Northern's growth for the last 40 years is high quality welding. Our 50+ welders handle projects from 24GA sheet to 1" plate - and everything in between.

Our Welding Skill Set

Heat and Distortion Control

Heat and distortion are critically important due to aluminum's high thermal conductivity & coefficient of thermal expansion. Our team's experience allows us to hold extremely tight tolerances despite these challenges.

From Thin to Thick

It's rare that a project is outside of our comfort zone. Material thicknesses from 0.020" to 1", and various materials and alloys and tempers of Aluminum are all in our wheel house.

Cosmetic and Structural

Our certified welders don't just "pass code." Their welds must both be structurally sound and aesthetically pleasing.

AWS D1.2 and ASME Code Welding

Certified Welding Inspectors On Staff

A very large percentage of our projects now require AWS or ASME welding procedures (WPS). With two CWIs on staff, we design and control welding parameters to ensure a very high standard of weld quality and strength.

Advanced Welding Technology

Wire Feed TIG Welding

A cold wire feed TIG process provides fast deposit rates and lower filler metal costs. The mechanized process can improve weld quality in the hands of a skilled operator. Cold wire feed is often preferred over MIG welding on projects where high quality welds are required but for the speed and lower cost of GMAW welding.

Aluminum Welding Equipment

Northern has a substantial investment in welding equipment designed for Aluminum welding. For GMAW, push-pull guns address the wire feeding issues associated with aluminum, and give the operator precise control over the heat input to the part. For GTAW, new digital pulse TIG machines make welding aluminum almost as easy as carbon or stainless steel.
